Flashcards in Work and Power Deck (8):
1

What is energy?

Energy is the ability to do work

2

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

3

What is work done equal to?

To energy transferred

4

How do you work out GPE?

mass x g x height
mgh

5

How do you work out kinetic energy?

1/2 x mass x speed squared
1/2mvsquared

6

What is power?

The rate of transfer of energy or the rate of doing work

7

How do you work out power?

power = work done / time taken
P= W/t

8

How does the conservation of energy produce a link between GPE and KE and Work?

KE gained = GPE lost
