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
energy: 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 princple of conservation of mechanical energy
A
In the absense of air resistance or any other external forces the mechanical energy of an object is remains constant
6
Q
potential energy
A
Potential energy is the energy an object has due to its position or state.
