Work and power Flashcards
1
Q
work done equation?
A
work done = force x distance
W = F x d
2
Q
what does work done = ?
A
work done = energy transferred
3
Q
gravitational potential energy equation?
A
gravitational potential energy = mass x gravitational field strength x height
GPE = m x g x h
4
Q
kinetic energy equation?
A
kinetic energy = 1/2 x mass x velocity2
KE = 0.5 x m x v2
5
Q
Define power and what is the equation?
A
- The rate of energy transfer (or rate of doing work)
Power = work done
time taken
P = W
t
