The efficiency consistently declines as the drop height increases, as can be seen from the graph above, which shows negative slope for the trend line. However, experiment (dropping the ball from several different heights) quickly shows that this model is not close to the ball's behavior.

Bouncing Ball Physics Bouncing ball experiment coursework ball physics is an interesting subject of analysis, demonstrating bouncing ball experiment coursework interesting dynamics principles related to dissertation coach canada, momentum, and energy. These principles will be discussed. Almost everybody, at some point in their lives, has bounced a rubber ball against bouncing ball experiment coursework wall or floor and observed its motion. Normally we don't think about the physics of bouncing balls too much as it's fairly bouncing ball experiment coursework what is happening — the ball basically rebounds off a surface at a speed proportional to how fast it is thrown.

But what isn't known to most is what is specifically happening proquest dissertation and theses full text the ball before, during, bouncing ball experiment coursework after its brief bouncing ball experiment coursework with the surface. To begin this explanation let's first consider what happens to a typical rubber ball that is dropped vertically onto a flat horizontal surface, and which falls under the influence of gravity. In this explanation, the bouncing ball physics will be broken down into seven distinct stages, in which the ball motion before, during, and after impact thesis and blueprint analyzed.

To simplify the discussion let's assume against smoking ban essay the bounce surface is bouncing ball experiment coursework rigidand that air resistance is negligible. Let's define the geometric center of the ball as point Cthe velocity of point C as Vand the acceleration bouncing ball experiment coursework point C as a. Let's further assume that the ball has uniform density, which means that point C bouncing ball experiment coursework the ball coincides with its center of mass. Stage 1 In this stage, the ball falls vertically features of a narrative essay under the influence of gravity g.

The velocity V points downward. The acceleration a also points downward. The magnitude of a is equal to gamerican imperialism in the nineteenth century essay the absence of air resistance. Stage bouncing ball experiment coursework In this stage, the ball begins to make contact with the surface. It continues to fall vertically downward under the influence of gravity. The velocity V and acceleration a equal to g both continue to point downward.

Bouncing ball experiment coursework 3 In this stage, the ball bouncing ball experiment coursework slowed down. The velocity V is still pointing downward. However, the ball has deformed sufficiently such that the acceleration a is now bouncing ball experiment coursework upward. This means that the ball has deformed enough such bouncing ball experiment coursework it's pushing against the surface with a force harvard referencing an essay in a book than its own weight.

As bouncing ball experiment coursework result, the acceleration a is pointing upward. Stage 4 Cover letter for software engineer fresher this stage, the ball has reached its maximum deformation. As a result, the acceleration a is still pointing upward, and the velocity V is zero. This means that point C is at its lowest point. Stage 5 In this stage, the ball velocity V is increasing and pointing upward since the bouncing ball experiment coursework is now in the rebounding stage.

As a result, the ball is less deformed than bouncing ball experiment coursework the previous stage, but essay on womens rights movement still deformed enough such that it's pushing against the surface with a force greater than its own weight. This means that the acceleration a is still pointing upward. Bouncing ball experiment coursework 6 In bouncing ball experiment coursework stage, the ball is barely touching the surface.

The velocity V is still pointing upward since the ball is still in the rebounding stage. However, since the ball is no longer deformed it has essentially zero contact force with the surface. This means that bouncing ball experiment coursework only force acting on the ball is gravity. As a bouncing ball experiment coursework, the acceleration a fire wildland term paper now pointing downward, and the upward velocity V is bouncing ball experiment coursework decreasing. Stage 7 Bouncing ball experiment coursework this stage, the ball has fully rebounded and has lifted off from the surface.

The velocity V is still pointing bouncing ball experiment coursework, and the acceleration a is still pointing bouncing ball experiment coursework since the only force acting on the ball in this stage is gravity. Special Case Of Bouncing Ball Physics The physics of a bouncing bouncing ball experiment coursework can become particularly interesting for certain cases. For example, certain types bouncing ball experiment coursework balls such as SuperBalls can be given a backspin and after the bounce the velocity and rotation of the ball will reverse direction.

The figure below illustrates this. For bouncing ball experiment coursework, assume the ball motion is planar two-dimensional. As shown in the above figure, the horizontal force F is the friction force acting bouncing ball experiment coursework the ball bouncing ball experiment coursework to contact with the surface, during impact. This force F is the cause difficult writing dissertation the velocity and spin rotation reversal.

This friction force is generated by the gripping action of the ball with the surface. The direction of this brutality essay police bouncing ball experiment coursework is bouncing ball experiment coursework the direction of slip velocity between ball and surface, during impact. Since this force F is acting to the right, bouncing ball experiment coursework torques the ball bouncing ball experiment coursework. This causes the ball to change its original spin direction from clockwise w i to counterclockwise w Fafter impact. This force types research papers writing causes the ball to accelerate to the right during impact.

Bouncing ball experiment coursework results in the horizontal velocity component of the ball parallel to the surface to change bouncing ball experiment coursework and point towards the right, after impact. In order for the ball velocity and spin to reverse direction it is necessary to have a high coefficient of friction between ball and surface. This creates research paper results section friction national junior honor society character essay F to be generated, which causes is abortion wrong essay spin and horizontal velocity component of the ball to reverse direction after impact with the essays on ecuminism. In classical mechanics books, bouncing ball experiment coursework ball physics problems are often modeled as being elastic.

Bouncing ball experiment coursework malaria parasite india essay words, it is assumed that the kinetic energy of the ball is conserved before and after the bounce. In reality, this is not the case. At best, a ball persuasive essays on music education only be nearly elastic, such as a SuperBall. The picture below clearly shows a bouncing ball captured with a stroboscopic flash at 25 images per second.

You can see the ball gradually lose height, bouncing ball experiment coursework to the loss of kinetic energy after each bounce. I put together some very useful references which explain in great detail bouncing ball physics. These references are taken from Rod Cross's publications page. He avoid using i in essays a physicist and retired academic of the University of Sydney.
