Unit 6: Impacts and linear momentum.
What do you get when you multiply mass times velocity? Momentum! Momentum can explain—or predict—what happens when objects with different masses and velocities collide with one another. Let's bump our way into this important and relevant concept.
Video transcript. - Let's solve a couple of problems on momentum changes. Here is the first one. A .5 kilograms ball of clay moving at 20 meters per second hits a wall and stops, sticks to it in .1 seconds. Find the change in it's momentum and the force exerted by the wall on it.

This article explains two-dimensional collisions in physics, covering key concepts and examples.
Momentum (P) is equal to mass (M) times velocity (v). But there are other ways to think about momentum! Force (F) is equal to the change in momentum (ΔP) over the change in time (Δt). And the change in momentum (ΔP) is also equal to the impulse (J). Impulse has the same units as momentum (kg*m/s or N*s).
