200
The ability to do work
What is energy?
200
Formula for kinetic energy
What is KE = 1/2mv2?
200
The rate at which energy is transferred
What is Power?
200
Transfer of thermal energy through moving particles through currents
What is convection?
200
This quantity tells how much easier a machine makes doing work
What is mechanical advantage?
300
The energy of motion
What is kinetic energy?
300
This tells us that the amount of energy at the beginning and end of any interaction must always stay the same

300
All six simple machines
What are lever, pulley, wheel and axel, screw, wedge, and inclined plane?
400
Stored energy
What is potential energy?
400
The addition of potential and kinetic energies
What is mechanical energy?
400
The unit of Power
What is a Watt (W)?
400
Definition of temperature
What is the average kinetic energy of particles in an area or object?
400
Nothing is 100% efficient, so some energy is always lost as this type of energy
What is thermal energy?
500
Einstein's equation that helped us to equate mass and energy
What is E = mc2?
500
The potential and kinetic energy at the maximum height of a ball thrown straight up with 1,000 J of energy
What is KE = 0 J and PE = 1,000 J?
500
The amount of work done when a book is lifted from the ground
