Multiple Choice

Which of the following best describes the difference between potential energy and kinetic energy?

Potential energy is stored energy due to position, while kinetic energy is the energy of motion.

Both potential and kinetic energy are forms of energy that depend on an object's temperature.

Potential energy is the energy of motion, while kinetic energy is stored energy.

Potential energy and kinetic energy are both types of thermal energy.

Verified step by step guidance

Begin by understanding the definitions of potential energy and kinetic energy. Potential energy is the energy stored in an object due to its position or configuration. Kinetic energy is the energy an object possesses due to its motion.

Consider examples of potential energy, such as gravitational potential energy, which is the energy stored in an object as it is held at a height above the ground. Another example is elastic potential energy, stored in a compressed or stretched spring.

Examine examples of kinetic energy, such as a moving car or a flowing river. The faster an object moves, the more kinetic energy it has.

Clarify the misconception that potential and kinetic energy are related to temperature. Temperature is a measure of thermal energy, which is different from potential and kinetic energy.

Conclude by identifying the correct statement: Potential energy is stored energy due to position, while kinetic energy is the energy of motion. This distinction is fundamental in understanding energy types in physics.
