(4 cards)
1
Q
Gravitational potential energy
A
The stored potential energy of an object due to position in a gravitational field, associated with the weight of a body at a given vertical height above the Earth’s surface
2
Q
Kinetic energy
A
The energy of a body due to its motion
3
Q
Conservation of energy
A
The total energy of a closed system remain constant: energy cannot be created or destroyed
4
Q
Work-Energy principle
A
The total work done by all the forces acting on a body is equal to the change in kinetic energy of the body
