The coefficient of restitution is the ratio of speeds of a falling object, from when it hits a given surface to when it leaves the surface. In laymans terms, the coefficient of restitution is a measure of bounciness. It basically is a property of collisions and depends upon the materials that are colliding. In this experiment, the coefficient of restitution between two balls, (a glass marble and a steel ball bearing) and the apparatus it is colliding with will be determined. AIMS To determine the coefficient of restitution between two balls, (a glass marble and steel ball bearing) and the apparatus it is colliding with. THEORY When two bodies collide, equal and opposite forces act on each body and will cause a motion. If there is no external force exerted to the system, then momentum will be conserved. Momentum is defined as (keg. M/s) and is a vector in the direction of v. (Newtons Second Law) equation (1) Impulse is defined I dot as which has useful applications in solving problems for forces when very short times are involved, such as during collisions. By taking the equation (1 ) for an integration, it shows that the impulse due to a Orca over a given time period is equal to the change in momentum as shown in equation (2). Equation (2) Figure 1 Consider the collision of the bodies in figure 1, there are equal and opposite forces (Newtons Third Law) acting on each body for the same amount of time during the collision. This condition can be represented mathematically as in equation (3). . Equation (3) Conservation of momentum tells that GIG + GO = 0 during a collision.
