The effect of temperature on the duration of time between the first and second bounce of the ball RESEARCH QUESTION How does the temperature of the ball influence the duration of time between the first and second bounce when a ball is dropped from a fixed height? INTRODUCTION In this experiment, the effect of temperature on the duration of time between the first and second bounce of a bouncing ball is tested. In this experiment, the bouncing ball is stored at different temperatures and then tested on how the length of time between the first two bounces changes with temperature when the ball is dropped from a fixed height. BACKGROUND According to the Law of Conservation of Energy, energy is neither created nor destroyed, but can be transformed from one form to another, although the amount of energy remains the same. In this ball dropping experiment, a ball is dropped from a fixed height of h1. It then bounces upward after hitting the ground to a maximum height of h2 and travels downward to hit the ground again during time t, as shown in Figure 1. Figure 1. Bouncing the ball from a height . Before the ball is dropped, the ball is lifted upwards from its supporting surface. When the ball is lifted, potential energy (PE) is acquired by the ball as it is raised to the heighth1 above the ground. As h1 h2 t BallAmeerah Syed the ball is dropped, it falls towards the ground and its potential energy transforms into kinetic energy (KE) due to its motion. The ball's kinetic energy continues to increase as the ball gains momentum, until it finally hits the surface. When the ball collides, the kinetic energy transforms into other forms of energy. When it hits the surface, some of the energy is transformed into sound energy and another part is transformed into thermal energy by the... middle of the paper... doing his experiment was that at first I decided to use a thermometer to measure temperature; however, this wouldn't be possible with a bouncing ball so I used an infrared heat gun. To further improve the accuracy of the experiment, I will use a sound recorder with an accuracy better than 0.01 s and an infrared thermal laser gun more accurate than 2%. Finally, the experiment conducted in this report clearly shows that when a ball is dropped from a fixed height at different temperatures, the time difference between the first and second bounce increases with increasing temperature, and the equation obtained through the experiment for the temperature versus time difference between the first and second bounce had an absolute error in the slope of only 0.0007 s/°C and the absolute error in the intercept of only 0.0291 s.
