Choose one of the variables you listed in #4, and design an experiment to test it. Identify your study strength and weaknesses. Yes, as the ball is oscillating about the equilibrium position (in height) and goes back to its initial position after a period of time. You will then take your bounces and their respective time intervals to a spread sheet. 3. The third stage is the point at which the ball is momentarily deformed, and bounces off the ground in an upward direction until it reaches its maximum height. A bouncing ball follows a projectile motion which is moving near the surface of the earth in a curved path due to the effect of gravity. Following are some sample information that you may find: Everyone has played with balls that bounce, but few people truly understand the physics behind a bouncing ball. CoR = coefficient of restitution = (speed after collision)/(speed before collision). If the coefficient to restitution = 0.7, a ball dropping from h1in a vacuum would reach the height of 0.7 h1 after bouncing. Controlled: - Same ball. Is a bouncing ball a simple harmonic motion? This did not happen in my experiment however. Free Bouncing Ball Experiment Essays and Papers | 123 Help Me Without a control you cannot be sure that changing the variable causes your observations. WebPhysics Lab 1 - Bouncing Ball - Hardik December 2019 PDF Bookmark This document was uploaded by user and they confirmed that they have the permission to share it. A real-life bouncing ball example would experience an oscillatory motion which would gradually lose energy, causing the height of the bounce to reduce over time until eventually, the ball came to a stop. This will be repeated five times, possibly more (for accuracy), for each height and the top and bottom results will be discounted. WebRamp and ball, controlled study lab report. The force that causes a ball to bounce is the reaction force described by Newton's third law of motion. For example, we could have used a ruler on the top to help us read how high up the tennis ball bounced, and we could have made sure the partner taking measurements did so from a consistent height. Do you think e is constant for your ball? What purpose does a control serve? Physics Ia on Bouncing Ball WebThis experiment,is an investigation into the maximum height of the bounce of a ping pong ball when it is first released.This is because of the unpredictability of the bounce not always reaching the same height.This we can assume their are many factors effecting the bounce of the ping pong ball.The following experiment will determine how different This is impossible. 15 inches, and the golf ball bounced 26 inches. 8. tennis and baseball) includes the CoR test. ThatQuiz This means for the ball to reach terminal velocity the drag force has to be bigger and for the drag force to be bigger the ball has to fall faster (so that more air particles hit the ball every second). Height will be the variable that we will vary. will differ from the height that the ball would have reached had it been dropped in a vacuum. Type your answer here: The independent is the variable you change, The dependent variable is the variable you observe to determine the impact of the independent variable, and control variable is the constant, which is something that is assigned a value, and it will not change in the experiment. At this level, science becomes even more interesting and powerful.8. For the lower heights the flight time of the ball was extremely short and again it was difficult to move ones head over the distance from h1 to h2 in order to obtain accurate results. It was more reliable to use the middle three results as it automatically discounted any anomalies; assuming two similar anomalies were recorded for one height, if they were then they both would be discounted.
