Work, energy and power Flashcards
1
Q
What is the definition of energy?
A
A measure of the capacity to do work
2
Q
What is the definition of work?
A
The energy transferred by a force (when a force moves through a distance)
3
Q
Work Done =
A
Force x distance moved
4
Q
Power =
A
Force x velocity
5
Q
What are the 3 types of energy in mechanics?
A
Kinetic energy
Potential energy
Strain energy
6
Q
Kinetic energy (KE) =
A
1/2 x m x V^2
7
Q
Potential energy (PE) =
A
force x distance (m x g x h)
8
Q
Power =
A
Energy / time
