Momentum: Students learn to define, give the MKS units for, and calculate momentum and to use the impulse equation to explain situations involving impulse and change in momentum.

Since momentum is conserved, and momentum is mass times velocity, the white ball's mass-times-velocity before the collision has to be equal to its mass-times-velocity, plus the red ball's mass ...

Learn how to understand and model collisions including explosions in terms of momentum, velocities and the forces involved for Higher Physics.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Learn about momentum and the forces that can cause it to change, and about what happens to momentum in an explosion or collision.
