Question

2 what causes a change from potential to kinetic energy? a. mass is increased b. a force is applied c. an decrease in temperature

Explanation:

Potential energy is stored energy, and kinetic energy is the energy of motion. When a force is applied to an object, it can cause the object to move. For example, if you push a book that is at rest (has potential energy due to its position), the force you apply makes it move (now has kinetic energy). Mass being increased affects the amount of potential or kinetic energy (as \(PE = mgh\) and \(KE=\frac{1}{2}mv^{2}\)), but it doesn't cause the conversion from potential to kinetic. A decrease in temperature is related to thermal energy changes, not the conversion between potential and kinetic energy.

Answer:

B. a force is applied
