EEI Ball Bouncing
Introduction
Gravity is a force that pulls all objects on Earth to its surface at a rate of 9.8m/sec. Gravity is an acceleration of a free falling object (Encyclopedia Britannica, 2014). Gravitational potential energy (Egp) is a concept from the law of gravity. As an object is positioned with a gravitational field, the object can store energy which is called gravitational potential energy (Physicsclassroom.com, 2014). As the object begins movement or work the energy transfers into kinetic energy. Kinetic energy (Ekr) is an expression of energy in motion. When an object is in the act of work or movement the energy becomes active and transfers from potential into kinetic (Hyperphysics.phy-astr.gsu.edu, 2014). Velocity (V) is a vector and is a measurement of speed. Speed is the distance travelled over the time it took to reach its destination. Velocity is the displacement of an object over the time taken (Burrows, 2007). The coefficient of restitution is the measurement of elasticity between two objects (Racquetresearch.com, 2014). In this extended experimental investigation the coefficient of restitution will be measured between a ball and the ground.
Throughout this extended experimental investigation the theory of whether or not different changing different variables can change the rate in which a ball can fall at and the height in which it bounces at. The motion of a bouncing ball can be analyzed into the motion of before, during and after impact of the ball contacting the surface. This investigation will analyse and break down the motions of a ball being bounced, into seven dynamic stages. The geometric center of the ball will be defined as C, the velocity of the ball will be represented as V and the acceleration of C will be shown as a. To create a fair test between trials it will be assumed that the surface on which the ball is being bounced is flat, smooth and hard along with the ignorance of air resistance.
