Depending on your view of things, this may be the most violent of our tutorials. Things will crash and collide. We'll learn about momentum and how it is transferred. Whether you're playing pool (or "billiards") or deciding whether you want to get tackled by the 300lb. guy, this tutorial is of key importance.
What momentum is. A simple problem involving momentum.
In this video, David shows how to solve for the impulse and force applied during a dodgeball collision using the impulse momentum relationship.
Learn what momentum and impulse are, as well as how they are related to force.
Learn what conservation of momentum means and how to use it.
In this video, David shows how to use conservation of momentum for a situation where two objects bounce off of each other.
A simple conservation of momentum problem involving an ice skater and a ball
An example of conservation of momentum in two dimensions.
We finish the 2-dimensional momentum problem
Learn how to handle collisions in 2 dimensions...and get better at playing billiards.
In this video, David explains how to use a force vs. time graph to find impulse and solves an example problem to find the final velocity of a spaceship.
