12. An example of an action-reaction pair is the action force when you jump down onto a trampoline; your weight pushes down the surface and the reaction force when the trampoline pushes back up on you with a force . 13. Which has greater momentum: a small pick-up truck traveling at 55 km/h or a full-sized bus traveling at the same speed? 14. In space, which would accelerate at a faster rate: the space station or an astronaut? 15. State Newton’s first law. 16. During the Bill Nye Video, Bill used a rubber ball to demonstrate momentum. One of the balls was placed in liquid Nitrogen, and it was “flat”. Explain why it was flat. 17. Using Newton’s first law of motion in your answer, explain why a baby is better off riding in a car when it is placed in a special car seat that faces backward rather than forward. 18. Explain how a skyrocket works using one of Newton’s laws of motion. 19. What was the point of the music video “The Faster You Push Me” in Bill Nye? momentum mass; acceleration inertial less living on land

freefall center of Earth distance forward motion; freefall in the opposite direction second equal to your weight The full-sized bus has greater momentum. Both accelerate at the same rate. An object at rest will remain at rest and an object in motion will continue moving at a constant velocity until an unbalanced force acts on it. Gas laws state that as temperature decreases, the volume of gas decreases. If the car the baby is on experiences an unbalanced force (brakes or car crash), it won’t go flying off. Instead, the baby’s momentum will go towards the car seat and balance without causing the baby an injury. The skyrocket’s acceleration will depend on the force applied to it and its mass (Newton’s 2 nd law: ) It demonstrates how an unbalanced force adds distance, speed, and velocity on an object at rest.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
