Work, Energy and Power Flashcards
1
Q
Work Done
A
Energy Transfer
2
Q
Equation for work done (Force and distance in the SAME direction)
A
Work Done = force x distance
3
Q
Equation for work done (Force and distance in the DIFFERENT directions)
A
Work Done = ForcexCos(angle) x distance
4
Q
Power
A
How fast work is done
5
Q
Kinetic Energy
A
Energy something has because of its motion
6
Q
Kinetic Energy Equation
A
Ek = 1/2 x m x v2
7
Q
Potential Energy
A
Energy something has because it is stored due to an objects position, state or shape
8
Q
Potential Energy Equation
A
Ep = mgh
9
Q
Principle of conservation of energy
A
Energy can be transferred from one form to another, but it cannot be created or destroyed. The total amount of energy will always stay the same.
