Mechanical Energy Flashcards
1
Q
Potential energy
A
Energy and object has due to its position or state
Ep =mgh
2
Q
Gravitational potential energy
A
Energy an object has due to its position in a gravitational field relative to some reference point
3
Q
Kinetic energy
A
Energy and object has due to its motion
Ek = 1/2mv^2
4
Q
Mechanical energy
A
Is the sum of the gravitational potential energy and the kinetic energy of a system
Emech = Ep + Ek
5
Q
Conservation of mechanical energy
A
Energy cannot be created or destroyed but is merely changed from one form into another
