Newton’s 3rd Law is easy to say, but tough to apply. The problem is usually that many people know the catchy phrase, but don’t actually know the meaning of the words in the phrase. (1:23) We explore the gravitational force between you and the Earth. (2:11) But, how does the 3rd law apply to running on a track (2:44) or a wagon being pulled by a tractor? (4:18) We look at all of these scenarios and still had time to discuss what makes a rocket capable of getting into orbit and beyond. (5:26)The Question of the Day asks: (6:59)How does the force that the Earth pulls on the International Space Station compare to the amount of force exerted on the Earth by the space station?Thank you for listening to The APsolute RecAP: Physics 1 Edition!(AP is a registered trademark of the College Board and is not affiliated with The APsolute RecAP.

In Episode 24 we are headed to a carnival to hop on rides that will have your head spinning and your stomach doing flips. (1:01) Each rotational quantity has an analogous linear quantity that we encountered at some point throughout the year. The name of the game in rotational kinematics is to quickly learn the names of each variable and the units used to measure it. (1:54) The rotational kinematic equations are introduced, and should seem familiar. (4:03) Finally, we determine how far the door of our spinning amusement ride has traveled as it speeds up to top speed. (6:11)The Question of the Day asks: (7:17)What does the Greek letter that looks like the fishy thing represent and what is its actual name?Thank you for listening to The APsolute RecAP: Physics 1 Edition!(AP is a registered trademark of the College Board and is not affiliated with The APsolute RecAP.
