Mechanical Energy Flashcards
1
Q
Gravitational potential energy
A
The energy an object possesses due to its position relative to
a reference point.
2
Q
Kinetic energy
A
The energy an object has as a result of the object’s motion.
3
Q
Mechanical energy
A
The sum of gravitational potential and kinetic energy at a point.
4
Q
The law of conservation of energy
A
The total energy in a system cannot be created nor
destroyed; only transferred from one form to another.
5
Q
The principle of conservation of mechanical energy
A
In the absence of air resistance or any
external forces, the mechanical energy of an object is constant.
