Work and Power

Front

What is the formula for calculating work?

Back

Work = Force x Distance (W = F x d)

Front

If no distance is moved, how much work is done?

Back

0 joules (J)

Back

True

Front

What is the relationship between work and energy?

Back

Work is a transfer of energy.

Front

If a force of 5 N moves an object 3 m, how much work is done?

Back

15 joules (J) (W = F x d = 5 N x 3 m)

Front

What is power in terms of work?

Back

Power is the rate at which work is done (P = W/t).
