The force being very large he (the fielder) will feel severe pain, particularly in the bare hands. If the same ball is to be stopped in the same interval Δt by a fielder he must apply the same average impulsive force of figure (a). When a cricket ball is hit by a bat, it exerts an impulsive force on the ball and the impulse of the force on the balls is so great that it moves in the opposite direction with tremendous speed. At the instant t the elementary impulse is F.dt. Nylon ropes stretch considerably under tension and are favored by mountain climbers because the ropes. So if it takes more time to hit something then it would hurt less based on force being less. The total impulse of the force during the interval for which it acts is given by the summation of the impulse from instant to instant. In terms of impulse, FTP, the more F the less time, since they're inverse. It rebounds losing 75 percent of its total mechanical energy. Solved Example : A ball of mass 50 gm is dropped from a height h 10 m. The impact force or impulsive force F is much greater than the external forces like weight (mg) and frictional force, in general. The plot of an impulsive force is a curve which is zero in the beginning and the end of the interval showing a peak value at some intermediate instant. This impact force is known as impulsive force. In fact an impulsive force is variable force. In other words, the greater your impulse the less force you need to stop a moving object. Impulse: Impulse is the time needed to stop and object’s momentum over a given distance and time. Momentum can also be thought of how much force is backing a moving object. Thus the impulse of an impulsive force = change in momentum = vector FΔt. The more Momentum, the more force an object needs to stop your kick. The impulse of an impulsive force is the great change in momentum produced by it. Where vector F is the average force during the short interval Δt and vector a is the average acceleration produced. The force experienced by the coil of a moving coil galvanometer due to sudden flow of current is an impulsive force. When we kick a ball, the force on the ball is an impulsive force. A great force acting for a very short interval of time on a body is called an impulsive force.There are numerous examples of impulsive forces.
