Exploring Work, Kinetic Energy, and Potential Energy

What does mass refer to?

• The speed of an object

• The amount of matter in an object

• The energy of an object

• The force of gravity on an object

How does weight differ from mass?

• Weight is constant, mass varies

• Weight is the force of gravity on an object, mass is the amount of matter

• Weight and mass are the same

• Weight is the amount of matter, mass is the force of gravity
