- 2In terms of u and t s=ut+ 1/2 at^2
- 3In terms of v, a and t s=vt- 1/2 at^2
- 4In terms of u,v and t s=1/2 (u+v)t
- 5In terms of u, a and t v=u+ at
- 6In terms of v, a and s u^2=v^2 -2as
- 7In terms of u, a and s v^2=u^2 +2as
- 8s= u= v= a= t=Displacement / Distance
Initial Velocity
Final / Second Velocity
Acceleration
Time - 9The Moment of a Force about a point is....the magnitude of the force multiplied by the perpendicular distance from the point to the force or the line of action of the force
- 10A anticlockwise moment is A Clockwise moment isPositive
Negative - 11Moment of a Force=Force * Perpendicular Force
- 12Distance from Point to Centre of Mass in x or y direction=(Sum of (Mass*Distance from point))/
Sum of Masses - 13If a body if suspended the centre of mass will beDirectly below the point of suspension
- 14Kinetic Energy =1/2 m v^2
- 15Work Done =Force * Distance cosθ
- 16Gravitational Potential Energy=Mass * Gravity * Height
mgh - 17λ= l= x=Modulus of Elasticity
Natural Length
Extension of string/spring - 18T=λx / l
- 19Elastic Potential Energy=λ e^2 /2l
- 20Power =Work Done / Time Taken
- 21Work done by a variable force =∫F(x)dx
- 22v =dx/dt
- 23a =dv / dt
- 24v =∫a dt
- 25s =∫v dt
- 26r =xi + yj + zk
- 271 rpm =2π / 60 rad s^-1
- 28v =rω
- 29a =rω^2
- 30a =v^2 / r
