Energy, work and power Flashcards
1
Q
Principle of conservation of energy
A
The total energy in a system remains constant and cannot be created or destroyed. It can only be converted from one form of energy to another without any loss in total energy.
2
Q
Formula for gravitational potential energy
A
GPE = mgh
3
Q
Formula for kinetic energy
A
KE = 1/2mv^2
4
Q
Formula for work done
A
W.D. = Force * distance
5
Q
