Test Description: Energy Practice Questions
Instructions: Answer all questions to get your test result.
1) What is the difference between potential and kinetic energy?
A
Potential is the energy of an object due to an applied fore, while kinetic is energy stored after the applied force.
B
Potential is the energy stored after an applied fore, while kinetic is the energy used from the applied force.
C
Potential energy is the energy of an object due to its position, while kinetic energy is energy due to its motion.
D
Potential energy is the energy of an object due to its motion, while kinetic energy is energy due to its position.
