Front

What are the two factors that determine work?

Back

Size of the force and distance.

Front

Back

20 J

Front

Define 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 = Force x Distance.

Front

What is the relationship between work and energy?

Back

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

Front

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

Back

The work done is also doubled.

Front

If no movement occurs, is work done?

Back

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