> a make sure you understand the meaning of each of the symbols including this one Δ which is called delta

> b make sure you are able to rearrange all of these equations so that any one of the symbols are made the subject.

v =u + at
x= ut +1/2at²
v²=u² + 2ax

Moment of F about O= F x( perpendicular distance from F to O)
Sum of anticlockwise moments about any point=Sum of clockwise moments about that point

F= mΔv/Δt=Δp/Δt
Impulse=FxΔt=Δp

Power P=F x ν

Activity A=λN
