Momentum and Collisions
Momentum has size and direction, the formula is:
momentum (kgm/s) = mass (kg) X velocity (m/s)
Momentum is conserved when no external forces act, the total momentum before is the same as the total momentum after
Force causes changes in momentum, the formula for this is:
Force acting (N) = change in momentum (kgm/s)/ time taken for change to happen (s)
A larger force…
