Work Practice

Front

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.

Front

What is the formula for calculating work?

Back

Work (W) = Force (F) × Distance (d) × cos(θ), where θ is the angle between the force and the direction of movement.

Front

What is the unit of measurement for work?

Back

The unit of measurement for work is Joules (J).

Front

True or False: Work is done only when the force applied is in the same direction as the movement of the object.

Back

True.

Front

If a force of 20 N is applied to move an object 3 meters, how much work is done?

Back

60 Joules.

Front

What two conditions must be met for work to be done?

Back

A force must be applied, and there must be movement in the direction of the force.

Front

What is the relationship between work and energy?

Back

Work done on an object results in a change in energy of that object.

Front

If no movement occurs, is work done?

Back

No, if there is no movement, then no work is done.

Front

What is the work done when a force of 5 N moves an object 4 meters?

Back

20 Joules.

Front

What happens to the work done if the distance is doubled while the force remains constant?

Back

The work done is also doubled.
