100
You multiply force by this in order to get work done.
What is distance?
100
We use these to do work on objects and to reduce the force needed to move objects.
What are machines?
100
m*g*h

What is what energy cannot be?
300
The amount of work done over time
What is Power?
300
Useful work output divided by total work input
What is efficiency?
300
potential energy
What is stored energy?
300
what an object needs to be doing in order to have kinetic energy
What is moving?
300
The only thing we can do with energy.
What is tranform it to another form?
400
In order to do work against gravity, we must do this to an object.
What is raise it to a greater height?
400
mechanical advantage
What is the ratio of output force to input force for a machine?
400
energy stored in the deformation of matter
What is elastic potential energy?
400
Work done
What is the change in kinetic energy of an object?
400
What happens to "lost" energy in a certain situation.
What is turned to heat?
500
Watt
What is the unit of power?
500
ratio of actual mechanical advantage to theoretical machanical advantage
What is efficiency?
500
the energy stored in molecular bonds
What is chemical potential energy?
500
This is what happens to the kinetic energy when you double the object's velocity
What is quadruples?
500
What happens to the total energy of a closed system
What is does not change?
