Flashcards in Work and Power Deck (8):
What is energy?
Energy is the ability to do work
What is the equation for work done?
Work done (W) = force applied (F) x distance through which it is applied (d)
J = N x m
What is work done equal to?
To energy transferred
How do you work out GPE?
mass x g x height
How do you work out kinetic energy?
1/2 x mass x speed squared
What is power?
The rate of transfer of energy or the rate of doing work
How do you work out power?
power = work done / time taken
