Question

Which statements describe kinetic and potential energy? Check all that apply.

Energy can be stored in the position of an object.
Energy is not present in a moving object.
Energy can be stored in the position of the particles that make up a substance.
Energy exists as movement of the particles of a substance.
Energy is greater in faster-moving particles than in slower-moving particles.
Energy is lower in objects with greater mass than in objects with less mass.

Answer 1

Correct answers:
- Energy can be stored in the position of an object. (True — describes potential energy.)
- Energy can be stored in the position of the particles that make up a substance. (True — microscopic/chemical potential energy.)
- Energy exists as movement of the particles of a substance. (True — microscopic kinetic energy, e.g., thermal energy.)
- Energy is greater in faster-moving particles than in slower-moving particles. (True — kinetic energy increases with speed, KE = 1/2 mv^2.)

Incorrect:
- Energy is not present in a moving object. (False — moving objects have kinetic energy.)
- Energy is lower in objects with greater mass than in objects with less mass. (False — mass often increases energy for a given speed or position; energy is not generally lower for larger mass.)
