Energy (gravitational, Kinetic, Mechanical, Conservation Of Mass) Flashcards
1
Q
Potential energy
A
The energy an object has due to its position or rate
2
Q
Gravitational potential energy
A
The energy an object has due to its position in a gravitational field relative to some reference point Ep =mgh
3
Q
Kinetic energy
A
The energy an object has due to its motion. Ek = 1/2 mv^2
4
Q
Mechanical energy (Emech)
A
The sum of the gravitational potential energy and the kinetic energy of a system. Emech = Ep + Ek
5
Q
Law of conservation of mechanical energy
A
The total amount of mechanical energy, in a closed system in the absence of dissipating forces, remains constant.
