Chapter 1
Introduction Bouncing ball physics is an interesting subject of analysis, demonstrating several interesting dynamics principle related to acceleration. Almost everybody, at some point in their lives, has bounced a rubber ball against the wall or floor and observed its motion. Normally we don`t think about the details of bouncing balls physics too much as it`s fairly obvious 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 happening …show more content…
Kovalcin, 2004. The ability of a surface to rebound a ball is determined both by nature of the surface and the nature of the ball. Maximum height will occur upon rebound when energy is not dissipated into some other form such as heat, sound or a permanent change in shape. A steel ball bouncing on a steel plate will bounce almost to the same height from which it was dropped.
Basic concepts behind bouncing balls include kinetic energy. Kinetic energy describes the energy on an object has while in motion. Balls often bounce higher when dropped from greater heights. This occurs because of the additional kinetic energy built up with the additional falling distance. Part of the kinetic energy dissipates when the ball contacts with the floor and uses the remaining kinetic energy to bounce back up. Thus, higher heights mean more kinetic energy to bounce back. …show more content…
Adair, a ball bounced of a hard surface losses a specific fraction of its mechanical energy with each bounce.
CHAPTER 3
METHODOLOGY
Materials:
Balls (different sizes)
Measuring tape/ Meter stick
Ground
Timer/Stopwatch
General Procedure:
Preparation for the experiment area
Set all the materials that will be needed in the experiment. Attach the measuring tool on the wall, the other end on the floor and the other end on the wall. Zero must be placed on the floor area. Ensure the conditions of the ball.
Experiment
Hold one ball at a time, level the height of your hand with the ball on the end of the meter stick (*make sure that every ball has the same starting height). Drop the ball from the starting height, start the timer, count each balls’ bounce, measure each balls’ bounce height.
CHAPTER 4
RESULTS AND DISCUSSION
This chapter presents the data gathered and observations obtained from the experimentation. Furthermore, it shows the discussion that supports the underlying problems under investigation.
