If you push on a door that says pull is work being done of the door? Why or why not?
No because work is the use of force to move an object. You exerted a force but did not move the object.

what is the work energy theorem?
state the formula

What two variables influence an objects kinetic energy and how?
Mass and speed
More mass = more kinetic energy
More speed = more kinetic energy

State the law of conservation of energy
Energy can neither be created nor destroyed. Instead, all forms of energy can be converted or transformed into other forms.

What is mechanical energy and what is the equation for calculating total mechanical energy?
Mechanical energy is the energy that an object has because of its motion or position/condition. (combined potential and kinetic energy)
Mechanical energy = KE + PE

According to the law of conservation of energy, in theory, a roller coaster should never stop moving. However, we know that it eventually stops. Where does the energy go?
some is converted into thermal energy due to friction
