Work and Power

Front

What is Work?

Back

Work is done when a force is exerted on an object and it moves in the direction of the force.

Front

What is the formula for calculating Work?

Back

Work (W) = Force (F) × Distance (d) where Work is measured in Joules.

Front

What units are used to measure Work?

Back

Work is measured in Joules (J).

Front

What is Power?

Back

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

Front

What is the formula for calculating Power?

Back

Power (P) = Work (W) / Time (t) where Power is measured in Watts (W).

Front

What units are used to measure Power?

Back

Power is measured in Watts (W).

Front

If a force of 50 N moves an object 2 m, how much work is done?

Back

Work = 50 N × 2 m = 100 J.

Front

How is Power related to Work and Time?

Back

Power is the amount of work done per unit of time.

Front

What is the relationship between Work and Distance?

Back

Work increases with greater distance if the force remains constant.

Front

What is an example of Work being done?

Back

Pushing a shopping cart across a store is an example of work being done.
