What is the definition of work in physics?

Back

Work is done when a force causes an object to move in the direction of the force. It is calculated as Work = Force x Distance.

Front

What is the formula to calculate power?

Back

Power = Work / Time.

Front

What is the standard unit of work?

Back

The standard unit of work is the Joule (J).

Front

What is the standard unit of power?

Back

The standard unit of power is the Watt (W).

If a force of 10 N moves an object 3 m, how much work is done?

Back

30 J (Work = Force x Distance = 10 N x 3 m).

Front

In which scenario is work being done?

Back

When lifting a book, work is done because the book is moved against gravity.

Front

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

Back

250 W (Power = Work / Time = 3750 J / 15 s).

Front

What is the relationship between work, force, and distance?

Back

Work is the product of the force applied to an object and the distance the object moves in the direction of the force.

Front

If you push a cart with a force of 60 N for 2 m, how much work have you done?

Back

120 J (Work = Force x Distance = 60 N x 2 m).

Front

What happens to the work done if the distance is doubled while applying the same force?

Back

The work done is doubled because Work = Force x Distance.
