WebForce Laws of Motion of Class 9 Consider a ball kept on a table, we can move it by pulling or pushing. We can increase its speed by pushing it in the direction of motion. If we push it opposite to the direction of motion its speed will decrease. If the ball is in motion towards east, we push it towards north, the direction of will change. WebNewton’s first law gives the qualitative definition of force according to which force is that external cause which tends to change or actually changes the state of rest or motion of a body. Newton’s first law of motion is the same as law of inertia given by Galileo.
