Work, Energy and Power Flashcards
1
Q
Work done
A
Work done by a force is the product of the force and the displacement in the direction of the force
2
Q
Work done by gas
A
W=p (change in V)
3
Q
Power
A
work done per unit time
4
Q
kinetic energy
A
the energy possessed by a mass due to its speed/motion
5
Q
gravitational potential energy
A
the energy possessed by a mass due to its position in a gravitational field
6
Q
Elastic potential energy
A
the ability to do work by the object when it is deformed
7
Q
principle of conservation of energy
A
- energy cannot be created or destroyed
- it can only be converted from one form to another
- total energy of an isolated system remain constant
