Description: In Kinematics course we described motion of an object along a straight line path in terms of its position , velocity  and acceleration . We also saw that motion is of two types uniform and non uniform. But we did not discuss what causes motion? Why does the speed of an object change with time ? Do all motion require cause ? If so then what is the nature of this cause? Answer to these critical questions we seek to answer through this course.Newton’s laws of motion, three statements describing the relations between the forces acting on a body and the motion of the body, first formulated by English physicist and mathematician Isaac Newton, which are the foundation of classical mechanics.Newton’s first law: the law of inertiaNewton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. In fact, in classical Newtonian mechanics, there is no important distinction between rest and uniform motion in a straight line; they may be regarded as the same state of motion seen by different observers, one moving at the same velocity as the particle and the other moving at constant velocity with respect to the particle. This postulate is known as the law of inertia.The law of inertia was first formulated by Galileo Galilei for horizontal motion on Earth and was later generalized by René Descartes. Although the principle of inertia is the starting point and the fundamental assumption of classical mechanics, it is less than intuitively obvious to the untrained eye. In Aristotelian mechanics and in ordinary experience, objects that are not being pushed tend to come to rest. The law of inertia was deduced by Galileo from his experiments with balls rolling down inclined planes.For Galileo, the principle of inertia was fundamental to his central scientific task: he had to explain how is it possible that if Earth
