$\frac{F}{d}$

$Fd$

$\frac{1}{2}Fd^2$

$Fd^2$

the total momentum of the body

the power developed by the force

the change in kinetic energy

$\frac{1}{2}Fv$

$Fv^2$

$Fv$

$T = \frac{\lambda x}{l}$

$T = \lambda x$

$T = \frac{\lambda l}{x}$

speed

momentum

force

speed of approach over speed of separation

momentum after over momentum before

the mass ratio

speed of separation over speed of approach

the change in momentum

the change in kinetic energy

force times distance

mass times acceleration

$\frac{v}{r}$

$\frac{v^2}{r}$

$vr$

$\frac{r}{v^2}$

a new fundamental force that acts only in circular motion

always the force of gravity acting on the particle alone

the resultant of the real forces towards the centre

an extra force directed away from the centre of the circle

$v^2 = 0$

$v^2 = 2gr$

$v = gr$

$v^2 = gr$
