The effect of temperature on the time between the first and second bounce of the ballRESEARCH QUESTIONHow the temperature of the ball affects the time between the first and the second bounce when a ball falls from a fixed height? INTRODUCTION In this experiment, the effect of temperature on the 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 duration between the first two bounces changes depending on the temperature as the ball falls from a fixed height. BACKGROUND According to the law of conservation of energy, energy can neither be 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 falls from a fixed height of h1. It then bounces upward after touching the ground to a maximum height of h2 and moves downward to touch the ground again for time t, as shown in Figure 1. Figure 1. Ball bouncing from a height. Before the ball is released, the ball is lifted. of its resting surface. When the ball is lifted, potential energy (PE) is gained by the ball when it is raised to height h1 above the ground. When h1 h2 t BallAmeerah Syed, the ball is released, it falls towards the ground and its potential energy is transformed. in kinetic energy (KE) due to its movement. 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 is transformed into other forms of energy. When it touches the surface, part of the energy transforms into sound energy and part transforms into thermal energy from...... middle of paper ...... doing your experiment is is that at the beginning I decided to use a thermometer to measure the temperature; however, this would not be possible with a bouncy ball and so I used an infrared temperature gun. To further improve the accuracy of the experiment, I will use a sound recorder with an accuracy of better than 0.01 s and an infrared temperature laser. gun more accurate than 2%. Finally, the experiment conducted in this report clearly shows that when a ball falls 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 temperature as a function of time difference between the first and second bounce had an absolute error in the slope of only 0.0007 s/°C and an absolute error in the intercept of only 0.0291 sec.
