Work and Power

Front

What is Work?

Back

Work is defined as the product of force and the distance over which it acts. It is calculated using the formula: Work (W) = Force (F) × Distance (d). The unit of work is Joules (J).

Front

What is Power?

Back

Power is the rate at which work is done or energy is transferred. It is calculated using the formula: Power (P) = Work (W) / Time (t). The unit of power is Watts (W).

If 150 Joules of work is needed to move a box 10 meters, what force was used?

Back

15 N

How much work is done with a force of 200 N over 426 meters?

Back

85,200 J

If 68 W of power is produced in 18 seconds, how much work is done?

Back

1,224 J

Front

What is the relationship between Work, Force, and Distance?

Back

Work is directly proportional to both Force and Distance. If either Force or Distance increases, Work increases.

Front

What is the formula for calculating Power?

Back

Power (P) = Work (W) / Time (t).
