What is the formula for work?

Back

Work = Force x Distance.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is power?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.
