Answer:
Gymnasts always perform on padded mats because
- The padded floor increase the time. The time changes because the padded floor extends the time of the collision. The force is reduced by this time change.
Explanation:
- The Impulse Momentum Theorem states that the change in momentum of an object is equal to the impulse applied on it.
J = Δ P ---- (1)
Where J is impulse and Δ P is change in momentum
We also know that impulse is the net force applied on a object which is represented by the following equation:
J = F ΔT
Putting this equation in equation (1), we get:
F ΔT = Δ P
So, this shows when the time is increases then the impulse decreases due to which the gymnasts always perform on padded mats.
