Here's the breakdown:
* Momentum: 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: A measure of the change in momentum of an object. It's calculated by multiplying the force (F) acting on the object by the time interval (Δt) over which the force acts: Impulse (J) = F * Δt
The key relationship:
Change in momentum = Impulse
Δp = J
This means that if you apply a force to an object for a certain time, you will change its momentum by an amount equal to the impulse.
Example: Imagine hitting a baseball with a bat. The force of the bat hitting the ball over a short time interval creates an impulse, which changes the ball's momentum from being at rest to moving at a high speed.
