What force causes a roller coaster cart to slow down the most?
friction
weight
gravity
air resistance
What is the formula for Kinetic Energy?
KE = mass x velocity
KE= 1/2 x mass x velocity 2
KE = mass x gravity x height
KE = mass x velocity / 2
Whenever a moving object experiences friction, some of its kinetic energy is transformed into __________ energy.
thermal
electrical
nuclear
mechanical
The Law of Conservation of Energy states:
Energy can created or destroyed but not transformed
Energy cannot be created or destroyed, it can only transformed
Energy can't be created, destroyed or transformed
Energy cannot be created or destroyed.
