Instructions: Answer all questions to get your test result.
1) If a red ball is dropped from a height of 3 feet and a green ball is dropped from a height of 6 feet, which ball has the greater potential energy?
A
red because it is up higher off the ground
B
green because it is closer to the ground
C
green because it is up higher off the ground
