What is the difference between potential and kinetic energy?
a) Potential energy is the energy of an object due to its position, while kinetic energy is energy due to its motion.
b) Potential energy is the energy of an object due to its motion, while kinetic energy is energy due to its position.
c) Potential is the energy of an object due to an applied fore, while kinetic is energy stored after the applied force.
d) Potential is the energy stored after an applied fore, while kinetic is the energy used from the applied force.
