Newton’s Law Of Motion
Newton’s law of motion comprises of three physical laws which form the basis of classical mechanics. The laws are used to determine the distance moved by objects as a result of forces which act on it in relation to its size. According to these laws, bodies cannot move unless some forced is applied on them. (Cohen, and Whitman, 1999)The first law of motion states that if the sum forces resulting which are applied to an object are zero, then the velocity of that object will be constant. Therefore, an object which is not in motion will continue resting until unbalanced forces are applied on it similarly, an object which is moving will not change it velocity unless an unbalanced forces are exerted on it.
Objects which are moving in a straight line at a constant velocity therefore require external forces to be exerted on them so that they may continue moving otherwise the probability of stopping is very high (Cohen, 1999).Newton’s second law of motion states that objects change their momentum relative to the amount of force applied and in the direction of the force. Therefore, the motion of an object is dependent on the amount of force applied as well as the direction of the force such that the time rate of change is dependent on nature of force (Cohen, 1999).The third law of motion states that for any force which is felt by a body, another equal force is produced although in the opposite direction. According to this law, any force exerted on a body is faced with equal force acting against it which reduces any form of motion (Cohen, 1999)..
