Mechanical Energy Flashcards
1
Q
Potential energy
A
The energy an object has due to its position or state
2
Q
Gravitational energy
A
The energy an object has due to its position in a gravitational field relative to its reference point
Ep= mgh
3
Q
Kinetic energy
A
The energy an object has due to its motion
Ek=1/2m.v^2
4
Q
Mechanical energy
A
The sum of the gravitational potential energy and the kinetic energy
5
Q
Law of conservation of energy
A
Energy cannot be created or destroyed but merely change from one form into another
6
Q
Principle of conservation of mechanical energy
A
Emech at top = Emech at bottom
The energy remains constant
