The principle of conservation of momentum can be demonstrated using two trolleys that stick together on impact.Use a motion sensor linked to a computer or light gates linked to a data logger to record the velocity of the trolleys before impact and after impact.If the mass of the trolleys are known, the total initial momentum and the total final momentum can be calculated and compared.
