Question

1. from \kinetic energy\...kinetic energy is ______ potential energy (6 points)

○ not related to

○ the same as

○ the opposite of

○ all of the above

1. from \kinetic energy\...kinetic energy ________ speed. (6 points)

○ decreses with

○ increases with

○ is the same as

○ is unrelated to

Explanation:

For question 8: Kinetic energy is energy of motion, potential energy is stored energy. They can convert between each other but are not the same, nor direct opposites, so they are not unrelated.
For question 9: The formula for kinetic energy is $KE=\frac{1}{2}mv^2$, which shows kinetic energy rises as speed increases.

Answer:

1. the opposite of
2. increases with
