When a ball bounces it does not bounce all the way back up, why is this? When a ball drops, it will bounce back up, but not all the way back up, because energy is lost in heat, sound, gravity, and air resistance. Energy is lost in so many different ways that the ball does not have enough energy to bounce back up to its starting point. So if you drop a ball and let it bounce, it will never bounce up to its original point without external energy. The point of my experiment is to list and document the forces acting on a ball that is dropped from a certain height. There are so many forces acting on the ball it is impossible for it to bounce to its original height. The ball does not bounce as high because of air resistance and gravity pulling it …show more content…
When we drop the ball we measure the speed and height of the ball at the peak of the bounce and when it hits the ground. The point of the experiment is to find how many variables affect the ball when it bounces and when it hits the ground. When the ball hits the ground, it loses energy that becomes friction on collision with the ground, Creating heat and then again when you hear the noise of the ball hitting the ground that is more energy lost or transferred. Newton's third law states that every action has an equal and opposite reaction, The action is of the ball hitting the ground the opposite reaction is the ball bouncing back up when the equal reaction is the sound that you hear. Newton’s first law is an object in motion stays in motion unless acted on by an outside force, so when the ball hits the ground all that energy has to be converted into heat sound or inertia. When the ball hits the ground it rubs against the floor creating heat and friction and that is how some of the energy is lost, when the ball makes sound on contact with the floor it creates a sound and there is the more lost energy on top of gravity and air …show more content…
The part of the drop where the ball loses the most speed is when the ball hits the ground making heat and sound. Friction is when the ball rubs on the floor it is transferred into. heat the kinetic energy of the ball when falling is transferred into heat and sound when the air around the ball is displaced and that takes energy to do that and that is where the rest of the energy is transferred. Air resistance is friction because the ball is still displacing the air and using energy to do that as well as creating heat and sound so all the outside forces of the ball not counting friction is gravity and the act of dropping the ball. When we are holding the ball before dropping it has potential energy because if it drops it has all that energy to keep it falling down and has kinetic energy until it hits the ground and has potential energy. For instance the ball is touching the ground its velocity changes and starts moving up instead of down and then bounces back

Essay about Join: Nile and Great Ping Pong

Victoria, where the Nile starts, is the second largest fresh-water lake in the world. The only lake that is larger is Lake Superior, in between Canada and the United States. Now nobody knows for sure who first suggested the great ping pong ball experiment. It might have been dreamed up by some absent-minded, daydreaming inventor. Or, it could have been thought up by some great scientist. Or, it might have been thought up by a little kindergartener in Kalamazoo, Michigan. But the important thing…

Bright Spot Lab

This experiment successfully produced Fresnel’s bright spot using the procedure discussed earlier. Under these conditions a few things that could have done better and things that were odd compared to similar experiments were observed. A second experiment was attempted to test some of the observed results but was not successful. Variables tested To test the way Arago’s spot reacts to different factors variables were changed. The distances between objects was varied, and the size of the balls was changed…

Bouncing Ball Report Essay example

Bouncing Ball Report Aim the aim of this project is to find out which surface will the balls bounces the highest. Hypothesis I considered the concrete surface as the most reliable source for making the ball bounce higher for each one. Background Depending on this experiment, air temperature can make a big difference for a ball to bounce on different surfaces, as air temperature can affect the gas molecules inside the ball, by either expanding or contracting the molecules, making the ball bounce…

Ruler and Steel Ball Essay

craters of a steel ball on flour when dropped from a specific height. A steel ball is dropped at various heights over a bowl of flour. When the ball hits the flour, a crater is formed. What I am trying to investigate is the correlation between the height (x) at which the steel ball is dropped and the diameter (y) of the crater. Research Question How does the diameter of the crater depend on the height at which the ball is dropped at? Independent Variable: The height at which the steel ball is dropped at…

Best Conduit For Combustion Experiments

In this experiment our group decided to which type of chemical is the best conduit for combustion. We tested whether it had the best type of combustion of testing the amount of time the fire burned after stopping oxygen flow, what was the mass of the cotton ball after burning it with the respective chemical, and what was the color of the BTB after 5 minutes with the fire. We hypothesized that vaseline would have the best combustion since it is made out of petroleum. This meaning it has many high…

Mass and Time Essay

If we increase the mass of the balls dropped at the same height, then the time to fall will decrease, because gravity will have a larger effect on the larger mass. The hypothesis is incorrect because what was calculated from the experiment was not proven by the hypothesis. For example, a basketball weighs 518.2 grams took an average of 0.811 seconds to drop, versus the kickball that weighs 423.4 grams that took an average of 0.888 to drop. If the hypothesis was true, then the time it took for the…

Essay Energy Conservation Lab

Julian Yuliawan, Sean Kondas Energy: Conversion and Conservation Abstract The experiment performed was a test of the theory of conversion and conservation of energy for the elastic collisions of two steel balls. The apparatus used included two identical steel balls, a projectile launcher, and a pendulum. The distance traveled by a ball launched using potential energy stored in a spring was compared to the distance traveled by a ball launched using gravitational potential energy. Also, the ranges of the two launching methods were…

material of the soccer ball affect the speed of which it travels? Questions- What are soccer balls made of? What is speed? How do you measure speed? What is velocity? What is force? Hypothesis: If the material of the ball is TPU (Thermoplastic polyurethane) when kicked, then the soccer ball will travel the fastest. This is because the type of material reduces friction better than the other materials, polyurethane and synthetic leather. The speed of the balls are determined by the amount…
