1

Q

Power (Energy)

A

Power = Energy / time

2

Q

Power (Force)

A

Power = Force * Velocity

3

Q

4th equation for suvat not given

A

s = (u+v / 2) * t

4

Q

how to calculate speed if given time

A

speed = distance / time

5

Q

how to find force for rate of change of momentum

A

F = Δp / Δt

6

Q

how to calculate final kinetic energy

A

final kinetic energy = original kinetic energy + change in gravitational potential energy

7

Q

relationship between work done, force and distance acting in a line

A

work done = force * distance

8

Q

relationship between work done, force and distance acting at an angle

A

work done = force * distance * cos theta

F s cos(theta)
