• the four-person sled has more KE
• the four-person sled has less KE

The Law of Conservation of Energy states that

• energy cannot be created nor destroyed, only transformed or transferred
• energy can be destroyed but not created
• energy can be created but not destroyed

What two factors affect an object's kinetic energy?

• area and volume

• mass and weight

• weight and height

• mass and speed
