Introduction

Introduction: Definition of Momentum

Momentum as a vector quantity

Momentum and Newton's Second Law

In this video we apply the previous equations to a collision between a tennis ball and a basketball. We assume that the collision is perfectly elastic and that the mass of the basketball is much greater than the tennis ball.

The conceptual and short problems are located in the pdf attachment of this video. Try the problems on your own then watch the video solutions. Good luck!

This is a problem often found in momentum chapters of physics textbooks. I consider a projectile that explodes once it reaching the maximum height. I consider the case where the initial projectile has a mass 2m and it explodes into 2 fragments, each of mass m. One of the fragments stops and falls immediately below the explosion point. The other segment travels farther. This problem can be solved using projectile motion or position of the center of mass. Both approaches are presented.

In this problem i review the ballistic pendulum. I use conservation of momentum to find the velocity of the Block and bullet system immediately after the collision. I also use convervation of energy after the collision to relate the maximum height of the block+bullet to the initial kinetic energy of the bullet. This is a standard problem found in most physics textbooks.
