Momentum questions generally appear with general science and/or basic physics. Note that the final answer has the proper SI unit of momentum (kg x m/s) after it and it also mentions the direction of the movement.Ģ. A cannon ball weighing 35kg is shot from a cannon towards the east at 220mls, calculate the momentum of the cannon ball. Momentum must always have a direction and so the final answer must reflect the direction of the momentum or velocity.ġ. Find the momentum of a round stone weighing 12.05kg rolling down a hill at 8m/s. So therefore momentum = kg x m/s and SI unit for momentum is kg x m/s The car would have greater momentum, due to its larger mass. Where P = momentum, V = velocity and M = massīased on the above definition, it is clear that the momentum of a car and a bicycle both travelling at 20 m/s will not be the same, because although the velocity of the two objects are the same, their mass is different. The formula for calculating momentum is = This means that momentum measures the force produced by an object’s mass and velocity. Momentum can be described as the sum product of the mass of an object and its velocity.
