same mass, same inertia, but different rotational inertias. see, if you're sittin' next to someone who knows which one is gonna roll faster, when i release them both at the same time? okay gang, how about i say this, "i ain't gonna show you." i will show you after the exam next month, fair enough? how many say you know what i kinda would feel a little more secure if you showed me? i have thought it out, don't get me wrong, i am not one of these types that you're talking about sometimes, i have thought it out. but i still like to kinda confirm my hypothesis, please, please do it, please show me. show your hands. no, nobody need to see. all right no problem, all right. i ain't gonna show you. i will tell you what, 5 cents each, 5 cents each. give me a nickel each and i'll show you. get your nickels out, come on. this is probably the least part of your educational expense. come on, everyone get a nickel out. and those that don't pay have to go in the other room. go join the couch potatoes, we're going to turn the tv camera on. how about you guys

inertia. no force. we don't know why it keeps going. but we call that ignorance inertia. get the idea? nobody knows why it keeps going. we just know that it does and so we call that inertia. any forces acting on this ball, by the way, on this cylinder? any forces acting on it, right now? - yeah. - yeah. force of gravity. and force of gravity is pulling it straight down. isn't that true? okay. if the force of gravity is pulling it straight down, why doesn't it go straight down? by the way, is that accelerating right now? no, it's not. and if it's not accelerating, what does newton say about the forces that act on it? theory of equilibrium. zero. zero net force. in fact, that's the idea of the law of inertia. if you see anything that's not accelerating, then all the forces that may enact on it, all balanced out. let me show you how this thing looks. here's a cylinder like that. now there's no force this way, no force this way. but there is a force down and that's the force of gravity. and that force of gravity acting straight down right toward the center of the world, okay,

the amount of inertia. the amount of inertia you have-- you're pushing against, huh? so it turns out the relationship is that. let me write it down here because i got my chalkboard. let's put it up a little bit. in chapter two, we said this is what acceleration is. acceleration is a change in velocity with respect to time. that's what it is. acceleration is change. it's change how you move. now, we're saying how you get it, how you produce it. and we're saying now, you produce an acceleration by pushing on something, by applying some net force. but how much acceleration depends upon the amount of matter. this idea is newton's second law of motion. it's powerful. it's probably one of-- it's certainly one of the most important equations in physics. powerful. it took a powerful mind to figure that out. let me give you an example. it was galileo who dropped objects and showed that when you dropped them, they will fall together. let's do it right here. you've seen this before. i drop them. they fall together. galileo discovered that. and he found out they had the same acce

so momentum really involves not only inertia but how fast the inertia is moving, inertia and motion. you have that kind of idea. that's what we're gonna talk about today. and today's stuff is all common sense, and it's an outgrowth of newton's laws. if that roller skate is running down the hill and that mack truck is running down the hill and you gotta stop them. you gotta step up in front, put your hand there and force them to a stop. there's gonna be a difference, isn't there? it's gonna be a lot harder to stop the mack truck. why? because you're gonna have to decelerate it. you're gonna have to decelerate it. and it takes not only a lot of force to-- i mean, how much force are gonna take to decelerate the mack truck compared to the roller skate? a lot or a little. a lot. why? 'cause the mack truck has a lot of mass. so i need to decelerate that, gonna take a lot of force. remember we talked about acceleration. acceleration, what? the amount of force applied upon a particular mass will yield a particular acceleration. are we getting now so we can read equations? okay? that's newton

and so we said impulse is a change in the quantity, inertia in motion, moving inertia. we call that what? that oomph, what do we call it? begin with m. momentum. okay, don't be shy. and that's what we talked about, right? and we said for big changes in momentum, you'll have what kind of impulses? begin with b. big. for small changes in momentum, you'll have what kind of impulse. begin with s. small, all right? now, what happens when-- what happens to the change in momentum when bouncing occurs? larger or the same as if bouncing does not occur? begin with a l. larger. and we can show that with this device here. here's a dart. it's like a dart and i have a sharp nail in there. and what i'm gonna do is i'm gonna lift the dart up, and i'm gonna allow it to swing against that wall. it's gonna make a collision. watch this. the block did not tip. i'll try it again. the block did not tip. this time, i'm going to remove the point. and now, i have just rubber here. this time, when i swing it, it's going to... bounce. and when it bounces, more impact or less? more. wow, hands down

and ultimately, it is easier to have inertia in washington than to have courage. >> you know, ali, it seems like recently you've been trying to give some good news lately about where things were headed. and now we talk about a 2% cut to medicare specifically over the next eight years. you have talked a lot about this. but what is the impact on jobs? i heard 66,000 physicians, hundreds of thousands of other health care people. >> yep. >> what are you hearing specifically? >> a number of the associations, the lobby groups, national medical association, national hospital association, the national nurses' association, have come up with some numbers. and they're saying over the course of these forced budget cuts, it could end up being three quarters of 1 million jobs. and this is in an area, health care, which has been growing, one of the bright spots, one of the things people train into in so many different levels. it's a ladder profession. so it would be devastating to see that degree of cuts, not just in the services that we're not going to get that you so effectively described. but in

my bottom line on that is, quickly, that the question here is whether you have institutional inertia of, particularly in a collective bargaining context that cannot get to some of the bigger issues of principle but have been enunciated here today. the parents want to do it, kids are responding. the problem is, at the present time, at least in my context, the statewide contract has not yet been able to be achieved. we achieved at the negotiating level, but we have not been able to get the board of the union to get it to the membership. if push comes to shove and we have to continue to impose the contract we will take it up but the point. with all the things i just mentioned and those that have been covered here today, i have a few quick points i would like us to consider. this is what i'm finding. we have not spent much time talking about class differentiation. what about compensation. i was a probation officer and i got paid the same whether i was dealing with traffic tickets or murder. it's the start getting into compensation differentiation, you get on a slippery slope very quickly

it has to do with the idea we call inertia. when something is moving, it's gonna keep on moving unless something messes with it. and so that when that rolls off, if there's nothing pushing it this way, then it would just keep going at the same speed. like when this ball is rolling along and now i push it. when i push it, it gains speed. but if i don't push it, it will just keep rolling steady, steady, steady with no change. and, furthermore, there's nothing this way obstructing it. now, there is some air drag, but very, very little compared to the tendency of that ball to just keep crashing through. so the ball goes steady, steady, steady. and rolling off the tabletop, if there's no gravity, would continue steady, steady, steady. but it doesn't continue like that, because there is gravity. and gravity pulls it down. what gravity is gonna do is like this. the ball we just hear it dropping, if i let it go, it falls here maybe. then falls in here, then falls in here, and then maybe fall down to here, okay? and then i'll have like

let's give people the advantage of saving more and put the power of inertia to work for them. number two is maximizing savings through the automated programs. recognizing and inertia and the need to save there are programs for the future of the to protection act that increase the contribution levels. the annual increase programs are the primary way workers are increasing their contributions. our data shows that close to one-third of all contribution increases last year were attributed to an increase program. unfortunately they are underutilized only 11% of employers are offering them. it may feel a bit onerous but when aligned with an annual salary increase, these programs can increase savings while minimizing the impact to take home pay. number three, and critically important as education and guidance. more than ever workers are responsible for saving and planning for their retirement. they need help understanding a range of financial topics from the most basic information about how to enroll and how much they should save to the more complex topics such as proper asset alloca

there is an institutional inertia in the united states the only way we deal with people who are resentful or dislike us is by trying to kill them all so there's none of them left. the real problem is the more attacks we wage and more bombs and drops we drop, the more people there are who want to attack the united states, we're exacerbating the problem of terrorism rather than solving it. >> john: brennan was also asked if the c.i.a. and white house believed it was possible for the agency to kill a suspected american terrorist in the u.s. as well as overseas. he evaded that artfully. but is that power inherent in the documents you've seen? does the executive claim the right to kill a u.s. terrorist suspect in this country without due process? >> it is a really critical question. the white paper that was just leaked to michael at nbc news where the justice department purported to tell congress about the rationale about why they can kill without due process said they're only the answering the question as to whether or not the president has power in places where capturing accused terrorists i

we're starting 2013 with a fair amount of inertia in the housing market. home sales are up about 9%. housing starts up at about 25% and house price indexes have turned around. they bottomed out in 2012 and we've had positive inertia and i think that will continue into 2013. what i will touch on today is what is driving the housing market right now. i think a lot of it is based on low mortgage rates. i will talk about that. i'm going to talk about the trends we've seen, house prices are up about 5% to 6% over the last year. i think we're going to see another 3% to 4% increase in 2013. i will share some notes about what we see for the mortgage market. let's start with housing demand. as i mentioned, we've seen it pick up in sales and construction activity. i think in part, this is driven by the affordability that we've seen in the marketplace. the national association home buyer affordability and the higher it is the easier it is for a typical family to buy a home. when they reduce this affordability, they incorporate three key ingredients. those three are,
