Rotating wheels of vehicles throw out mud, mudguards fitted over the wheels prevent this mud from spreading. When a straight running car turns sharply, the person sitting inside feels a force radially outwards. The tendency of an object to oppose any change (unbalanced force) in its direction of motion and continue to stay in direction is called inertia of direction. When a bus or train stops suddenly, the passengers sitting lean forward.Ī person who jumps out of a moving train may fall in the forward direction.Ī bowler runs the ball before throwing it so that this speed of running gets added to the speed of the ball at the time of the throw.Īn athlete runs through a certain distance before taking a long jump because the velocity acquired during the running gets added to the velocity of an athlete at the time of the jump, and hence he can jump over a longer distance.Ī ball is thrown in the upward direction by a passenger sitting inside a moving train.īack to the hands of the passenger, if the train is moving with constant velocity.Īhead of the passenger, if the train is retarding (slowing down).īehind the passenger, if the train is accelerating (speeding up).Ī body cannot change its direction of motion by itself. Now, if the cardboard is removed with a sudden jerk, the coin falls into the tumbler.Ī body cannot change its state of uniform motion by itself. The dust particles in a blanket fall off when it is beaten with a stick.Ī coin is placed on cardboard, and this cardboard is placed over a tumbler, such that the coin is above the mouth of the tumbler. When a horse starts suddenly, the rider falls backwards. When a bus or train starts suddenly, the passengers sitting inside tend to fall backward. When we shake a branch of a mango tree, the mangoes fall. Larger the inertia of a body, the more will be its mass.Ī body cannot change its state of rest by itself. Mass of a body is a quantitative or numerical measure of a body's inertia. In simple words, inertia is a measure of the tendency of an object at rest to stay at rest or of an object in motion to stay in motion. It is difficult to change the state of rest or uniform motion of a body of heavier mass and vice-versa. The mass of a body is the measure of its inertia of translational motion. Inertia is the property of a body due to which it opposes any change in its state. Thus, Newton explains his first law of motion based on the inertia of rest, the inertia of motion, and the inertia of direction. The law defines the force and states it as a factor, which can change the state of the object. A body continues to be in its state of rest or uniform motion in a straight line unless compelled by an external force to change its state. Newton's First Law of Motion is also known as Galileo's law of inertia. To be specific, the first law of motion defines the force qualitatively, the second law of motion gives a quantitative measure of the force, and the third law of motion states that a single isolated force doesn't exist. The three laws of motion describe the relationship between a body and the forces acting upon it, along with the body's motion corresponding to those forces. The three laws of motion proposed by Newton are three physical laws, which together form the basis of classical mechanics. While there are many theories on motion given by scholars and ancient scientists, Newton's Laws of Motion are the most popular. According to him, resistance (inertia) or friction affects a body in motion or at rest. Galileo Galilei takes a different angle to explain the laws of motion. It is called Aristotle's Fallacy, and Newton's Laws come under Aristotle's Fallacy. According to Aristotle, a constant continuous force is required to keep a body in uniform motion which is not actually true.
