This worksheet helps students work with elastic collisions. First, the student is asked to distinguish between elastic and inelastic collisions. Then, the student is asked to draw a "before" picture and an "after" picture of an elastic collision and to solve the problem numerically. Finally, the student examines a basic two-dimensional elastic collision.
This is appropriate for a high school physics course. I usually use it as either an in-class activity or as homework soon after I complete the "elastic collision" lab involving two carts on a track. It could also be used as a review of the concept of elastic collisions for an AP Physics course.
This homework is included in the complete lesson on Elastic Collisions
