Physics 601 – Momentum VO Why does a gun kick when it`s fired
... Look at these two darts. One has a nail embedded in its tip, while the other has a rubber tip. We’ll pull the nail-tipped dart back so that it is released from a certain height. Watch what happens when it collides with a wooden block. You can see that a force is exerted on the block, but not enough ...

... down to the earth. If you pick up an object and drop it, it accelerates toward the center of the earth. By accelerate, you know that the object starts out slow and gets faster and faster as it moves down. The gravitational force acts between any two masses. The mass of the earth provides the gravity ...

The Law of Conservation of Momentum
... Elastic collisions conserve both momentum and kinetic energy. This is a slight change on the conservation of energy we had in the last section where energy could have different initial and final forms. Even inelastic collisions conserve energy; the energy gets converted into forms other than kinetic ...
