Back

Front

Calculate the kinetic energy of a 2 kg object moving at 3 m/s.

Front

What best describes kinetic energy?

Back

Energy of motion

Front

What increases the gravitational potential energy of an object?

Back

Raising the object higher

Front

Define work in physics.

Back

Work is done when a force causes an object to move in the direction of the force.

Front

What is the unit of power?

Back

Watt (W), which is equivalent to Joules per second (J/s).

What is the formula for gravitational potential energy?

Back

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with mass; doubling the mass doubles the kinetic energy if velocity remains constant.

Front

What is the relationship between work and energy?

Back

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