formula: Momentum (kg m/s) = Mass (kg) x Velocity (m/s) Momentum is a vector quantity that describes the motion of a moving object and indicates how much force is required to stop an object. The Law of Conservation of Momentum states that The total momentum before an event is equal to the total momentum after an event.
1) Attach the piece of A4 paper to the bench top with masking tape. Rule two parallel lines on the paper, 20 cm apart.
3) Pull the trolleys apart and hold them with their front ends on the two lines.
Release the trolleys. The trolleys will accelerate towards each other and collide at the same time. How far the trolleys travel travel in a given time is proportional to their relative velocities.
4) Determine where the trolleys collide and mark the collision point on the paper.
5) Measure the distance from one line to the collision point, and the same for the other one. Because the trollies collide at the same time, there is no need to measure the time because distances are proportional to the collisions.
6) Add various masses to one (or both) of the trollies and repeat the experiment. Test five different weight combinations
