Energy Basics

Front

What happens to kinetic energy if you double the velocity of an object?

Back

Kinetic energy is quadrupled (multiplied by 4).

Front

What happens to kinetic energy if mass is doubled?

Back

Kinetic energy is doubled.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

How do you calculate power?

Back

Power is calculated as work done (force x distance) divided by time.

Front

What happens to gravitational potential energy if height is doubled?

Back

Gravitational potential energy doubles.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground.

Front

What is the formula for gravitational potential energy?

Back

Gravitational potential energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.
