Which statement best compares potential and kinetic energy? A. Objects always have more potential energy than kinetic energy.

B. Only kinetic energy increases when the velocity of an object increases.

C. Only potential energy decreases when an object's height increases.

D. Objects always have more kinetic energy than potential energy.

Which of the following correctly describes the early view of catastrophism?

How is zig zagging a form of acceleration?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
