Impulse of a force measures the effect of the force. It is the product of force `(F)` and time `(t)` for which the force acts. Mathematically, impulse `=Fxxt`. It is equal to change in linear momentum of the body.
For a given change in linear momentum, `Fxxt=constant`. If `t` increases, `F` decreases and vice-versa. For example, a player lowers his hands while catching a cricket ball. This would be increase `t` the time of catch. Therefore, `F` would reduce, i.e., his hands will not get hurt badly.
Read the above passage and answer the following questions:
(i)Why is crockery wrapped in straw or papers etc.?
(ii) Why are vehicles like scooter, car, bus, trucks provided with shockers?
(iii)What message does this paragraph give you for your day to day life?

(i) Crockery is wrapped in straw or paper to avoid breakage. In case of mishandling, the impact takes longer time to travel to crockery through straw//papers. As `t` increases, `F` decreases,i.e., impact on crockery reduces, preventing the chance of breakage.
(ii)The vehicles like scooter, car,bus, trucks are provided with shockers. When they move over an uneven road, impulsive forces are exerted by road. The function of shokers is to increase the time of impact. This would reduce the force//jerk experienced by the rider of the vehicle.
(iii)The message conveyed by the paragraph is that to achieve any goal in life, you have to put in your sincere efforts. More intense are the efforts, lesser will be the time required in achieving the goal. One has to plug all the top holes in the process so that efforts are not wasted.
