Physics equations

1. distance travelled = average speed x time

2. acceleration = change in velocity / time taken

3. force = mass x acceleration

4. weight = mass x gravitational field strength

5. momentum = mass x velocity

6. wave speed = frequency x wave length

7. density = mass / volume

8. work done = force x distance

9. wave speed = distance / time

10. density = mass / volume

11. power = work done / time taken

12. charge = current x time

13. potential difference = current x resistance

14. power = energy transferred / time taken

15. force on a spring = spring constant x extension

16. electrical power = current^2 x resistance
