What is Potential energy?
When a pendulum swings back and forth, what energy transformations occur?
What is potential energy to kinetic energy and back to potential energy?
According to the law of conservation of energy, what happens to the total energy in a closed system?

In a flashlight, what energy transformations occur to produce light?
What is electrical energy to light energy?
In a roller coaster ride, how does the total mechanical energy change as the coaster moves along the track?
What is it remains constant if air resistance is negligible; otherwise, some mechanical energy is converted into thermal energy due to friction?
Newton-meters
What are Joules (units for Work)?
The opposite direction of the motion of the object.
What is the direction of friction?
