In reality, as the roller coaster moves along the track, some energy would be "lost". Where does the "lost" energy go? **CHOOSE TWO (2)**

• It disappears completely and never comes back

• It is transformed into thermal energy by friction

• It is transformed into sound energy

• It turns into matter

The law of conservation of energy states

• Every action has an equal and opposite reaction

• Energy cannot be created or destroyed, it can only transform from one form to another

• Force = Mass x Acceleration

• Objects in motion remain in motion until a force acts upon. Objects at rest stay at rest until a force acts upon it.
