Determine the KINETIC energy of the cart at position "A"

Determine the POTENTIAL energy of the cart at position "B"

Determine the POTENTIAL energy of the cart at position "C"

Determine the TOTAL MECHANICAL energy of the cart at position "D"

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.

Which of the following are the two types of mechanical energy:

• Potential

• Kinetic

• Thermal

• Electrical

• Nuclear

What happens to the to the KINETIC energy as the ball falls from point A to point C?

• It decreases

• It increases

• It doesn't change

What happens to the to the TOTAL MECHANICAL energy as the ball falls from point A to point C?

• It decreases

• It increases

• It doesn't change

What happens to the to the POTENTIAL energy as the ball falls from point A to point C?

• It decreases

• It increases

• It doesn't change
