As an object falls...

1. What happens to the potential energy?

2. What happens to the kinetic energy?

3. What happens to the total energy?

Potential energy decreases, kinetic energy increases, total energy stays the same (conservation of energy!!!)

A 6 kg bowling ball is thrown at 7 m/s up a 3 meter tall ramp. Does the bowling ball make it to the top of the ramp?

No, it only makes it up 2.5 m

500

A bowling ball and a tennis ball are dropped off the side of a 100 m building. Which one will get to the ground first, and why?

They'll get there at the same time because their starting point, starting velocity, and acceleration are the same.
