The coefficient of restitution is the ratio of the final to initial speed between two bodies after the collision. 8. If you get more than one value, calculate and record the average. Based on your gathered information, make an educated guess about what types of things affect the system you are working with. h1will start at 2m and then move down in intervals of 10cm to 10cm. If you are using windows sound recorder program, you can view the recorded waves with an accuracy of 0.01 second. Controlled: - Same ball. When a player dribbles a basketball, as Kobe Bryant does here on the 2012 U.S. men's Olympic team, the ball actually transfers some of its energy on each The last stage is the point at which the ball has reached its maximum displacement, decelerates, and changes the direction of motion from upwards to downwards. In this project we will try to find out what factors affect the bounce of a dropped ball. Lerne mit deinen Freunden und bleibe auf dem richtigen Kurs mit deinen persnlichen Lernstatistiken. Controlling Variables Part 1 ( Video ) | Chemistry | CK-12 Foundation Air pressure will affect the balls fall slightly as the concentration of air particles per cubic meter varies with air pressure. WebThe scientific method consists of five steps: -Observation/research: The first step is to research and collect as much background information on your chosen question as you can. Several meter sticks for measuring the height of the bouncing ball or drawing a larger meter stick. Is the measurement method questionable or unreliable? 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. For a falling object the Coefficient to restitution (C, ) is equal to the velocity squared as the object is travelling at as it leaves the floor (v, ) divided by the velocity squared as it hits the floor (v, If a ball is dropped in a vacuum. These are parts of the experiment that you try to keep constant throughout an experiment so that they won't interfere with your test. The experiment was conducted as the method (below) states. It was decided that the first drop would start at 2m off the floor and then move down in intervals of 10cm to 10 cm off the floor.
