Different pieces of mass (500 g; 1 kg and 1.5 kg) were dropped onto a moving cart and learners observed the speed of the cart before the pieces of mass were dropped on the cart and the speed after the falling pieces of mass. The speeds were then compared. Momentum: Momentum is defined as the product of mass and velocity over a body. It is a vector quantity measured in kg.ms-1 (M.Mann, 2013). The law of conservation of momentum states that the total linear momentum of an isolated system remains constant. This means that the momentum of two bodies before the collision will be equal to the momentum of the two bodies after they collide and explode. This will only happen if the collision takes place in a closed system (no other forces act on the objects) (M.Mann, 2013). An example of this is Newton's Cradle. It is a row of five metal balls suspended by a wire on a frame. When the ball at the end (ball 1) is pulled and then released to collide with the ball next to it (ball 2), the momentum from ball 1 will not be lost but will be transferred from the third ball to the fourth until until it reaches the last ball which will rise to a height almost identical to the height to which the first ball rose. The fifth ball will then fall back and collide with the middle of the paper......ect for the weights of 1kg and 1.5kg, because the momentum before the collision was not equal to the momentum after the collision. . This is due to an experimental error which prevented the experiment from being an isolated system and therefore the law of conservation of momentum could not be executed.Report and declaration of plagiarism:Bibliography:1.
