Presentation transcript:

Types of Collisions Elastic collisions-Two objects collide, temporarily misshape, and spring away from each other… KE and momentum are conserved. Inelastic collisions conserve momentum but not KE…some energy is lost to non-conservative forces such as thermal energy/friction. Perfectly inelastic collisions require that the 2 objects are combined as a unit after the collision.

7-7 Collisions in 2 or 3 dimensions In these problems, you must use trig functions and the Pythagorean Theorem to solve for components. See sample Example 7-10
