Maxfli Softfli. 5), Requirements are the limits to designing or making a product or system. Tennis balls bounce about 53% of their dropped height, Super Balls about 85 or 90 % of their dropped height. (Grade
But since the rebound height depends on the drop height, the rebound height is called the dependent variable. Grades: Preschool and K-2 Length of Lesson: Approximately 45 minutes Related Video: "The Hawk Factor" episode Learning Goals: For example, if a ball of mass m is dropped from a height h1 onto a surface and it rebounds to a height h2, then the loss of energy is mg(h12h2). The excercise ball bounced the highest. 2), Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. . At the drop height, the tennis ball has gravitational potential energy, which is then changed into kinetic energy as it tumbles to the ground (Kajiyama, 2019). We could have used a video camera to look at the exact peak for each bounce. Repeat experiment 2 more times to produce accurate results 9. Research states that a basketball can bounce up to about 25 inches, and a tennis ball can bounce up to about 53 inches. Leave the tennis balls . What are all the different sports that are played with balls? Description of different graph types (line, scatter, bar, pie). Found inside – Page 91Science Experiment. BONUS. Bounce. Away! How much height does a ball lose with each bounce? Energy is the ability to do work. Potential energy is the energy that an object has because of its position. The energy of an object in motion ... Dropped ball from 12 inches above surface 3. recorded height of bounce. It is likely, however, that the true maximum bounce height … When the ball bounced up of the table we had to just guess and say the nearest bounce height of the ball. The differences in bounce height depend on the style of construction as well as the material the balls are made of. As a ball bounces, it warms. Could you play basketball with a superball? After running both tests on that ball, have the groups switch balls (rotate) and test a new ball until all balls have been tested by each group. Tape the butcher paper along the floor and up the wall so that when the ball bounces the paint will stay on the wall at the spot where the ball hits. What kind of surface? (Grades
The text has been developed to meet the scope and sequence of most university physics courses and provides a foundation for a career in mathematics, science, or engineering.

Elevating the ball to a certain height will cause it to gain gravitational potential energy that is equal to the amount given by the equation E = mass x gravity x height. The first test is the bouncing test off concrete garage floor. A. Once the "bounciness" of the ball has been determined, the ratio gives a bounciness index. Possible suggestions are to have the same student drop the ball and start the watch, or have the two students count down from five. I think that the _____ surface will help the ball bounce the highest. (Grade
Measure the height the ball reaches after the first bounce and record. Drop a ball from 1 foot off of the floor, slightly in front of a yardstick. Subject Areas:
5), Compare, contrast, and classify collected information in order to identify patterns. 3), Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. The first time you drop the ball do not take a measurement, just watch where the ball goes so the next time the observer knows where to look. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units— whole numbers, halves, or quarters. The bounce height of the ball is a function of the intrinsic qualities of the ball. Students will be able to feel the paint. Measure from the bottom of the ball. Controlled: - Same ball. I did an expieriment dropping a golf ball on cement and it bounced an average of 5.454545... does that mean that that would be the fraction of energy lost, or does it need to be tested on a designated surface? 1. is located 11 mm above the piezo. Easy Experiment. to the drop height) and the minimum being no elasticity (i.e. The best I have seen is called a Super Ball. Baseballs have less bounce than tennis balls or golf balls.
