![]() Implications of this work are a potential use of similar passive damping systems in sports technology and marine engineering. While the characteristics of the fluid (i.e., density, viscosity, etc.) affect the fluid motion (i.e., type and size of jet formation), the rebound characteristics remain similar for a given fluid volume independent of fluid type. We then used movie-maker to conclude the height at a certain time(s). At first, we dropped the filters from the grand staircase(5.4 meters) and then we did the same from 70 cm. (Make sure the bottom of the rule is on the floor.) 2. Place the meter rule flat up against the flat wall. Each time we changed the height from which the filters were dropped. Aim: To determine if initial height interferes or affects the rebound height Apparatus: A tennis ball, A meter rule, a flat wall and floor/surface, pencil, and paper Diagram: Method: 1. We had a racquetball so ours had a pretty high rebound height. To do this we dropped a ball at predetermined heights on a meter stick, and took a video to measure the rebound height of the ball. Drop the ball alongside a wall with a ruler or other tape measure fixed on the wall. The first lab we did in AP physics was to examine the relationship between the drop height and rebound height of a ball. ![]() Hypothesis: If I release a ball from a greater height then the rebound distance will be greater. Design an experiment to determine if this suggestion is true or not. The experimental results are analyzed in terms of acceleration, momentum and an energy method suggesting an optimal fill volume in the neighborhood of 30%. We used the same mount of coffee filter each time which made that variable constant. 1 Answer Sorted by: 2 As for measuring the rebound height, I would suggest you use a camera (make sure the camera is fixed, not hand held). A student suggests that there is a proportional relationship between the height from which a ball is dropped and its rebound height. Finally, we need to multiply the distance found by 2, as one bounce of the ball includes both a rise and fall. Images gathered through experimentation show that the fluid reacts more quickly to the impact than the sphere, which decouples the two masses (fluid and sphere), imparts energy to the fluid, and removes rebound energy from the sphere. Using the geometric sequence formula, the sum of the terms which are the heights of the ball after each bound: S n ( 1 r n) 1 r 6 m ( 1 0.38 5) 1 0.38 9.6 m. Surprisingly, this occurs on the second rebound or when the free surface is initially perturbed. Unlike an empty sphere, the internal fluid mitigates some of the rebound through an impulse driven exchange of energy wherein the fluid forms a jet inside the sphere. ap-calculus-bc/bc-series-new/bc-10-2/v/bouncing-ball-distance WebMay 13. This study investigates the impact dynamics of hollow elastic spheres partially filled with fluid. You decide to conduct an experiment on how drop height and bounce are related. ![]()
