Speed

Velocity

Distance

Mass

$s = ut + \frac{1}{2}at^2$

$v^2 = u^2 + 2as$

$v = u + at$

$s = \frac{1}{2}(u + v)t$

acceleration

speed

force

displacement

zero

maximum

equal to $g$

equal to $u$

every action has an equal and opposite reaction

resultant force equals mass times acceleration

a body stays at rest unless acted on

weight equals mass times gravity

$mg$

$mg\cos\theta$

$mg\sin\theta$

$mg\tan\theta$

$\mu mg$ always

$R$

$\mu / R$

$\mu R$

constant

decreasing at rate $g$

zero at the top

equal to the vertical component

$u$

$u\sin\theta$

$u\cos\theta$

$u\tan\theta$

force divided by the perpendicular distance

force times the time of application

force times perpendicular distance

mass times the acceleration of the body

at one end

at the pivot

at the heavier end

at its midpoint

the other support

the centre of the beam

the point of the load

any point not on the beam
