In padding helmets we have pads or cushions on it which will move inwards when ball hits the helmets
Now due to this the collision time will increase and ball is not immediately rebound with the helmets
so as we know the Newton's law
[tex]F = \frac{\Delta P}{\Delta t}[/tex]
so here if collision time is increased then we will have less force
so the impact of collision will be less
So the correct answer will be
A) It extends the time of the collision
On the application of padding, the time of the collision (or the reaction time) increases. Hence, option (A) is correct.
The average force acting on any object for a very small interval of time is called Impulse. As per the impulse-momentum theorem, "The product of average force and time interval is equal to the change in momentum.
The mathematical expression for the impulse-momentum theorem is,
[tex]F \times t = \Delta p\\\\F = \dfrac{\Delta p }{t}[/tex]
Here,
[tex]\Delta p[/tex] is the change in momentum.
t is the time interval or the reaction time.
F is the average force.
Clearly, the average force is inversely proportional to the reaction time. Due to padding, the reaction time increases, and the magnitude of average force decreases. This reduces head injury.
Thus, we can conclude that on the application of padding, the time of the collision (or the reaction time) increases. Hence, option (A) is correct.
