Equations

Distance = Speed x Time

(m)             (m/s)       (s)

Momentum = Mass x Velocity

(Kg m/s)         (Kg)       (m/s)

Change of momentum = Force x Time

 (Kg m/s)                         (N)        (s)

Work =     Force x Distance

(Joules)     (N)         (m)

Kinetic Energy = 1/2 x Mass x Velocity2

(Joules)                       (Kg)      (m/s)

1 of 2

Gravitational Potential Energy (GPE) = Weight x Height

(Joules)                                                 (N)            (m)
