![]() This means every object opposes the forces that try to change it state. In fact, every object resists any change in its state. This means that a body cannot change its state of rest or state of motion on its own. To turn a car moving along a straight road, we have to apply force on the wheels of the car. A body moving along a straight line will continue to move along the same straight line unless an external force is applied on the body to change its direction of motion.A body in uniform motion continues to move uniformly unless an external force is applied to change its speed.A body at rest continues to remain at rest until an external force is applied on the body to move it.Let’s discuss Newton’s First Law of MotionĪccording to Newton’s first law of motion:- ‘A body continues to be in a state of rest or in a state of uniform motion along a straight line, until and unless an external force is applied on the body to change the state.’ These three laws are known as Newton’s Laws of motion Newton further investigated the ideas put forth by Galileo regarding the motion of objects and formulated three fundamental laws that govern the motion of objects. In this blog, we will discuss Newton’s First Law of Motion.Īfter performing lots of experiments, Galileo concluded that an unbalanced external force is what is required to initiate the movement from the state of rest, and the object moves with a constant speed along a straight line when no force acts on it. This belief persisted till Galileo Galilee and Sir Issac Newton gave their theories about motion. People believe that this is because the state of rest is the natural state of an object and the state of motion is the acquired state and not the natural state of the object. ![]() You must have observed that a moving ball comes to rest after moving some distance. ![]()
