Question

Derivation of Elastic collision in 1 dimension.

Answer 1

An elastic collision is one that also conserves internal kinetic energy. Internal kinetic energy is the sum of the kinetic energies of the objects in the system. Figure 1 illustrates an elastic collision in which internal kinetic energy and momentum are conserved.

Truly elastic collisions can only be achieved with subatomic particles, such as electrons striking nuclei. Macroscopic collisions can be very nearly, but not quite, elastic—some kinetic energy is always converted into other forms of energy such as heat transfer due to friction and sound. One macroscopic collision that is nearly elastic is that of two steel blocks on ice. Another nearly elastic collision is that between two carts with spring bumpers on an air track. Icy surfaces and air tracks are nearly frictionless, more readily allowing nearly elastic collisions on them.

In this lesson, you'll learn how to solve one-dimensional elastic collision problems. You'll find that understanding the conservation of momentum and conservation of kinetic energy is essential to solving these types of problems.

Elastic Collisions

When you think about a collision, what normally comes to mind? For many people, it will recall two vehicles crashing into each other. Whether watching a TV show of cars crashing while in a race or seeing the aftermath of an accident on the road, you've probably had some first-hand experience in seeing a type of collision.

A couple of different things can happen when two cars collide. They can bounce off each other, or they can stick together. We call these two categories of collisions elastic and inelastic collisions respectively, and these categories apply to more than just car crashes. Any collision where two things bounce off one another, like a bowling ball hitting pins, is called an elastic collision. Similarly, any collision where two things stick together, like one football player tackling another, is considered an inelastic collision. In this lesson, we'll focus on the former and dive into learning about the physics that occur in a one-dimensional elastic collision.
