1.	Impulse of a force is a measure of total effect of the force It is given by the product of everage force and the time for which the force acts on the body . Impulse of a force is measured by the total change in linear momentum produed during impact Impulse ` vec(I) = vec(F)_("avg") xxt = vec (p_(2)) - vec(p_(1)) ` A given change in linear momentum can be produced by applying a larger force for a shorter time or by applying a smaller force for a longer time Read the above passage and answer the following questions (i) What is the function of shockers in autos (ii) What values of life do you learn from this study ?
Answer» (i) When autos ply over an uneven road , impulsive forces are exerted by the road The funcation of shockers is to increase the time of impact As `F xx t` = constant , therefore when `t` increases `F` decreases the force/jerk experienced by the rider of the vehicle raduces (ii) In day life the relation `F xx t ` = change in linear momentum = constant implies that to achieve any goal or to affect any change the product of force and time shall be constant when your efforts are weak you require longer time to achieve the goal .
