Physics Fast Facts: Work and Energy

Front

What is energy stored in a gravitational field?

Back

Gravitational potential energy.

Front

What is energy stored by a spring?

Back

Elastic potential energy.

Front

What type of force converts potential energy to other forms of mechanical energy when it does work?

Back

A conservative force.

Front

When is work done in relation to the direction of the net force?

Back

When an object moves parallel to the direction of the net force.

Front

What is done when a force acts on something that moves a distance parallel to that force?

Back

Work.

Front

What is the formula for calculating work?

Back

Work = Force × Distance × cos(θ), where θ is the angle between the force and the direction of motion.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy = 1/2 × mass × velocity².

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is power in the context of work and energy?

Back

Power is the rate at which work is done or energy is transferred.
