I used this clip when teaching about free-fall and projectile motion. Students forget that at the top of the parabola for a projectile a is still -9.8 m/s/s; the common answer is "0 m/s/s." This clip helped in the discussion of why that "0" isn't correct. and that really it's v that is 0 m/s. If v and a were both 0, then what happened to Peter would take place.
The crew is trying to reach the shuttle that already landed on the asteroid. While traveling to it, the crew members come across a giant ravine in the asteroid and have no way to cross it. Since there is less gravity on the asteroid, they try to jump over the ravine. They successfully jump over it, and their trajectory leads them away from the asteroid, but they manage to turn the engines back on in time to return to the asteroid.
Newton presents his findings on gravity to a group of scientists. Among the attendees are Sir Robert Hooke. During his explanation of the inverse-square law, Newton notices that Hooke appears to be stealing his work, so he abruptly ends his presentation.
Annie is driving a bus and sees a gap in the freeway ahead. She speeds up and successfully jumps across the gap. This clip illustrates a misconception about motion: the horizontal speed of an object does not influence how quickly it falls.
