Here's why:
* Momentum: Momentum is a measure of an object's mass in motion. It's calculated by multiplying an object's mass (m) by its velocity (v): Momentum (p) = m * v
* Impulse: Impulse is the change in momentum of an object. It's calculated by multiplying the force applied (F) by the time the force acts (Δt): Impulse (Δp) = F * Δt
The Key Relationship: Impulse is equal to the change in momentum. Therefore, a larger impulse results in a larger change in momentum.
Conclusion: A large force acting for a short time creates a bigger impulse than a small force acting for a longer time, leading to a greater change in momentum.
Example:
* Scenario 1: A baseball bat hitting a ball with a large force for a short time. This creates a large impulse, resulting in a significant change in the ball's momentum.
* Scenario 2: A gentle breeze pushing a feather. This creates a small force over a longer time, resulting in a smaller impulse and a less significant change in the feather's momentum.
