Work and Power Practice

Front

What is the formula for calculating work?

Back

Work = force x distance

Front

How much work is done when a force of 500 Newtons pushes a car 4 meters?

Back

2000 J

Front

What two factors does gravitational potential energy depend on?

Back

Height and mass

Front

What is the formula for calculating power?

Back

Power = Work / Time

Front

If a kitchen blender performs 3,750 Joules of work in 15 seconds, what is its power?

Back

250 W

Front

Define work in the context of physics.

Back

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

Front

What unit is work measured in?

Back

Joules (J)

Front

What is the relationship between work and energy?

Back

Work is a transfer of energy; when work is done, energy is transferred from one system to another.

Front

What is the unit of power?

Back

Watts (W)

Front

How do you calculate the gravitational potential energy of an object?

Back

Gravitational potential energy = mass x height x gravitational acceleration (g).
