The second law of motion is based on the amount of energy needed to move an object. The law states that whenever a force acts on a particular object, the object will accelerate based on the direction of the force. The law goes on to state that as long as the mass of an object is constant, increasing the force exerted onto it will also increase its acceleration. On the other hand, if the force remains constant, then the increase of the mass of the object will cause acceleration to decrease.
Applications of Newton
In a cricket match a fielder moves his arms back while trying to catch a cricket ball because if he tries to stop the fast moving ball suddenly then the speed decreases to zero in a very short time. Therefore the retardation of the ball will be very large. As a result the fielder has to apply a larger force to stop the ball. Thus, if he tries to stop a fast moving cricket ball the fielder may get hurt as the ball exerts a great pressure on the hands but if he tries to stop it gradually by moving his arms back then the velocity decreases gradually in a longer interval of time and hence retardation decreases. Thus the force exerted by ball on the hand decreases and the fielder does not get hurt.
2, A Fielder Moving his Hands Backward WhileTrying to Catch a Ball
3, An athlete before jumping runs some distance because this forward momentum may help him to jump high.
