Mo9-L1b: How are Energy and Work Related?

The student does work on the box when he lifts it.
Mo9-L1b How are Energy and Work Related? Once the box is in place, no work is being done.

KEY CONCEPTS:
1. How are energy and work related?

Vocabulary A-Z

Let us learn some vocabulary

work
The student does work on the box as he lifts it.
is the transfer of energy that occurs when a force The box’s kinetic energy and gravitational potential
makes an object move in the direction of the force energy increase.
while the force acts on the object.
The student is longer doing work on the box because
the box is not moving in the direction of the applied
force.

Key Concept
How are Energy and Work Related?

If you do work on an object, how will its energy
change?

Let’s Begin

Energy and Work

Work is the transfer of energy that occurs when a
force makes an object move in the direction of the
force while the force acts on the object.
Forces are pushes or pulls.

To do work on an object, an object must move in the
direction of the force.

Work is one only while the force is moving the object.
