Energy Concepts and Types

Front

Conservation of Energy

Back

Energy cannot be created or destroyed.

Front

Work

Back

When an object or living thing does work on another object, there is a transfer of some energy.

Front

Velocity

Back

Speed with direction; it’s a vector.

Front

Measurement for energy and work

Back

Energy and work are measured in joules (J).

Front

Power

Back

The rate at which energy is transferred.

Front

Equation for power

Back

Power = Energy transferred/time; watts = J/s.

Front

Kinetic Energy (KE) Definition

Back

Energy based on movement.

Front

Kinetic Energy (KE) Equation

Back

KE = ½ x mass x velocity².

Front

Factor influencing Kinetic Energy

Back

Velocity has the greatest impact on KE because it is squared in the equation.

Front

Source of Kinetic Energy

Back

It is transferred to the object; more velocity means more energy transferred.
