1) u=F(mg sin¤)/R(mg cos¤)

2) limiting frictional force (F)=UR

3) F(total)= F + mg sin¤ ...i.e force required to move a load up the plane

4) angular velocity (w)=¤/t..........where ¤=angle....T=TIME measured in rad.s-1

5) period of a motion... T=2#/w......where # =pie..and w=angular velocity

6) linear velocity.. V=WR....where W=angular velocity R=radius

7) Force F =ma...where m=mass....a=acceleration

8)centripetal force F = MV^2/R......where M=mass...V=velocity ..R=radius

9)centripetal force = mv^2/r

10) centripetal acceleration = v^2/r

11) Newtons law of motion ....
v = u + at.......1
s= ut + 1/2at^2.......2
v^2 =u^2 + 2as.........3
