This unit is about momentum. Momentum is defined as inertia in motion. The units of momentum is kilograms meter per second. This can be represented as P. the law of conservation of momentum states that momentum cannot be created nor destroyed, it can only change forms. The equation for this is Pin= Pout. Meaning momentum in equals momentum out. Impulse is the change in momentum. When to objects collide there are two types of collision elastic and inelastic. Elastic equations are bouncy and inelastic collisions are non bouncy or sticky. In class we did a lab for this with toy cars. We had a collision with velcro and a collision without velcro. From that we found that momentum was not lost in the collision. It was just transferred from one equation to another. Force is found by the change in momentum divided by the change in time.
