Kinetic Energy Review

The energy of motion

• Kinetic Energy

• Potential Energy

As mass increases, kinetic energy

• Increases

• Decreases

• Stays the same

• 12

• 12 J

Kinetic energy is ___ proportional to the mass of an object.

• indirectly

• directly

The faster an object moves, the ________ kinetic energy it has. 

• more
• less
• none of the above
• all of the above
