Momentum (11 of 16) Elastic Collisions, Example 1

Worked example for momentum and elastic collisions. Shows how to determine the final velocity of both masses after the collision. In this conceptual qualitative example mass one (m1) is in motion and mass two (m2) is at rest.

This problem uses conservation of momentum and kinetic energy to determine the final velocity of both masses.

In an inelastic collision the objects stick together. Due to deformation of the objects, the release of heat and increased vibrational energy, kinetic energy is not conserved. Momentum is conserved. In a perfectly elastic collision the objects do not stick together, therefore kinetic energy and momentum are both conserved.

Great stuff. Gotta watch this one again a couple of times haha. However, that is pretty much what I do with all your videos.
These videos are an integral part in my mission to be an expert in physics by the end of the year. Not just to know physics, but to actually understand it on a fundamental level and knowing how to apply it to everything I do.
Understand physics and you understand life just a bit more.

Thank you!!! We are doing this in our physics class this week... very helpful
