What are the units of work?

Back

Joules

Front

How does the size of the force affect the amount of work done?

Back

The bigger the force, the more work is done.

Front

What are the two conditions that must be met for work to be considered done?

Back

Force and movement.

Front

In which situation is work not done?

Back

Holding a 20-pound box above the floor.

Front

What is the formula for calculating work?

Back

Work = force × distance.

Front

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

Back

Work is the product of the force applied and the distance over which it is applied.

Front

Can work be done if there is no movement?

Back

No, work requires both force and movement.

Front

What is the significance of the direction of force in work?

Back

Work is only done when the force has a component in the direction of the movement.

Front

If a person lifts a box straight up, what type of work is being done?

Back

Positive work, as the force and movement are in the same direction.

Front

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

Back

The work done is doubled.
