Formulas

Speed(m/s) = Distance(m)/time(s)

v=s/t

Acceleration(m/s2)= change in speed(m/s)/time taken(s)

a=v-u/t

v2 = u2 + 2as

Force(N) = Mass(kg) x acceleration(m/s2)

F = MA

Weight(N) = Mass(kg) x Gravitational field strength(N/kg)

W=mg

Momentum(kgm/s) = Mass(kg) x velocity(m/s)

p = mv

Force(N) = Change in momentum(kgm/s)/Time(s)

Orbital speed(m/s) = [2{pi} x orbital radius]/time period

v=2{pi}r/T
