Work Practice Problems

Front

What is Work in physics?

Back

Work is defined as the product of force and the distance over which that force is applied. It is calculated using the formula W = F × d, where W is work, F is force, and d is distance.

Front

What is the formula for calculating Work?

Back

W = F × d

Front

If a force of 350N moves an object 40m, how much work is done?

Back

14,000J

Front

How much work is done when a force of 200N moves an object 20m?

Back

4,000J

Front

What is the unit of Work?

Back

The unit of Work is Joules (J).

Front

If no movement occurs, what is the work done?

Back

0J, because work requires both force and movement.

Front

What does it mean if work is done at an angle?

Back

When work is done at an angle, only the component of the force in the direction of the movement does work. The formula becomes W = F × d × cos(θ), where θ is the angle between the force and the direction of movement.

Front

What is the relationship between Work and Energy?

Back

Work is a transfer of energy. When work is done on an object, energy is transferred to that object.

Front

What is the difference between Work and Power?

Back

Work is the total energy transferred, while Power is the rate at which work is done. Power is calculated as P = W/t, where P is power, W is work, and t is time.

Front

How much work is done if a force of 20N is applied over a distance of 10m?

Back

200N*m or 200J.
