We have given that It feels better to catch a hard ball while wearing a padded glove than to catch it bare handed

We need to find that the ideas of this chapter to explain why

The force with a short time when an object receives a force is called the impulse, so it is the area under the curve of the force-versus-time graph and it is the same as momentum. The impulse is the quantity $J_x$and it is given as

$impulse=J_x=F_x∆t$ $\left(1\right)$

From equation $\left(1\right)$for $F_x$

$F_x=\frac{J_x}{∆t}=\frac{∆p}{∆t}$ $\left(2\right)$

The force is inversely proportional to the time $∆t$as mentioned above. To reduce the force the time must increases. The padded glove increases the time of the contact between the ball and the hands, so less force is exerted. When the hands are bare, the time of contact decreases, so the force increases causes.
