Physics and Energy Concepts

Front

Collision

Back

A crash in which two or more objects (things or people) hit each other.

Front

Conservation of Energy

Back

A principle stating that energy cannot be created or destroyed, but can be altered (converted or transformed) from one form to another.

Front

Energy

Back

The ability to do work. Objects possess more motion energy when moving faster (NYSED).

Front

Energy Conversion

Back

The conversion of one form of energy into another (e.g., from moving objects or by sound, light, heat, or electric currents).

Front

Energy Transfer

Back

Energy of the same form (e.g., energy of motion, heat energy) can be transferred from one object to another through a collision or direct or indirect contact (e.g., conduction or convection).

Front

Force

Back

An interaction that causes an affected object to be pushed or pulled in a certain direction.

Front

Motion Energy

Back

(Kinetic) energy that an object possesses by virtue of being in motion.

Front

Non-renewable Resource

Back

A resource that forms at a rate much slower than the rate at which it is consumed.

Front

Renewable Resource

Back

A resource that can be replaced at the same rate at which it is consumed.

Front

Stored Energy

Back

The energy possessed by an object by virtue of its position relative to others, stresses within itself, electric charge, and other factors. Includes gravitational, chemical, and elastic potential energies.
