energy and as it bounces back upwards it has kinetic energy again. Energy is also lost through heat and sound. I decided to use one type of ball, so the weight was constant. And the height it was dropped from, therefore I dropped it from a range of different heights so as to get a wide variety of results. The range was from 200 centimetres to 20 centimetres, measured at 20 centimetre intervals. My hypothesis is that the higher the ball is dropped from the higher it'll bounce back, the height
independent variable that will be tested. The tennis ball is the constant variable factor (the variable that is kept the same, to make the investigation valid). The ball will dropped from increasing heights (cm-25, 50, 75,100,125,150,175,200) and the bounce of the ball will be measured. A sample size of 3 results will be taken from each height the ball is dropped. The same investigation will then be repeated, but one of the independent variables will be changed. This will be the surface material the
repetitive emails "SPAM". The name stuck, and to this day junk email is still called Spam. These annoying emails were originally intended as a marketing ploy, simply to get a company's message out to as many people as possible. Now they are so annoying, I can honestly say that Spam is the absolute worst way to get your message across; these junk emails are never read, only deleted.
fans as they watch the teams battle out the game. Up and down the court, the turnovers, rebounds, fast breaks, and most of all the baskets make the games exciting. But have you ever wondered how these things happen? What enables the basketball to bounce, how does Kobe Bryant fly through the air, and why does the ball rotate backwards as it leaves a shooter’s hand and approaches the basket? These are all interesting questions and believe it or not they can all be answered with a discussion on physics
Height a Squash Ball Bounce Aim: To investigate the effect of temperature on the height a squash ball bounces. Prediction: I think that the higher the temperature of the squash ball, the higher the squash ball will bounce. I think that as the temperature doubles so will the height of the bounce. I think that they will be directly proportional. Scientific Knowledge: If you drop a ball onto a hard floor. It will rebound, but even the bounciest ball will not bounce back to its starting
Investigating the Bounce of a Tennis Ball after It Has Been Dropped From Certain Height Aim To investigate how high a tennis ball will bounce back after it has been dropped from a certain height How a Tennis Ball Bounces As the ball is elevated the ball gains gravitational potential energy equal to the ball's weight multiplied by its change in height1. When the ball is dropped, the height decreases, and therefore so does the gravitational potential energy. At the same time, the velocity
Factors that Affect the Bounce of a Ball Introduction There are many factors which will affect the bounce of a ball: · The size and shape of the ball · The material the ball is made from · The surface it is bounced on · The weight of the ball For example, a ball dropped on sand would absorb more energy than a ball dropped on a concrete floor. Aim To investigate the bounce of a ball. Prediction I predict that when you decrease the height you release the ball from
Investigating the Bounce of a Squash Ball This investigation is associated with the bounce of a squash ball. I will be investigating 4 different types of squash balls, which have different, bounce properties and compare them to each other and relate them to why each different type of squash ball is used. The relationship will be associated with how different balls are used at different levels of proficiency in the game of squash i.e. the squash balls that don't bounce much will probably
at the elements of dribbling. Dribbling is all based on conservation of energy and the two different types of collisions, elastic and inelastic. The more air pressure a basketball has inside it, the less its surface will bend or deform during a bounce, and the more its original energy will be stored in the compressed air inside (Bill Willis, 2001). The reason for this is that the air inside of the ball can return the energy of the ball better than that of the material of the ball, which is usually
referred to as sound waves. An echo happens when the sound waves reach a surface, bounce off of it and travel in the opposite direction. For optimum echoes, the surface should be perpendicular to the waves, and as frictionless as possible. In places like the Grand Canyons, you can hear many echoes because the sound waves bounce off of surfaces, then others bounce off of other surfaces, and some will bounce back to you, but at different times. In echolocation, bats send out short pulses that
Investigating How the Height From Which a Table Tennis Ball is Dropped Affects Its Bounce When a table tennis ball is dropped onto a surface it bounces. The height of the bounce depends upon a number of factors; the pressure of the air in the ball, the height from which it is dropped, its material, mass and its temperature; the type of floor surface, its temperature and its angle; and the acceleration due to gravity, the temperature and the air resistance of the air that the ball will pass
by A Table Tennis Ball After Several Bounces Aim: To investigate the amount energy lost, between bounces of a table tennis ball. I will also look to see if the fraction of energy lost is constant at each bounce. Prediction: The difference between the observed heights will lessen as the initial height of drop decreases. I predict that the change between the average heights will be large to start with but decrease slower the more number of bounces I do. Energy Background: Energy is what
connect via a T' connector which allows the bus to continue to the end of the cable. Due to the nature of this design when the data reaches the end of the cable if it's not properly terminated (which kills the signal) then we can receive what's called bounce back. This ricocheting of the data could severely hinder the communication pathing of the bus. As I recall there is a general rule of thumb for a bus topology which is the rule of 5-4-3-2-1. This means that you can have 5 data segments of which
will bounce to after having a loss or gain of energy due to sound or movement of the ball as it hits a hard surface. I will drop the ball 3 times altogether, on the second bounce I will look specifically at the point it is likely to bounce to so the results will be more accurate. After doing this three times I will then take an average to make it more accurate. This will then even out any freak results, which occur. While completing the experiment I will be taking note of the bounce height
Both Democritus and Epicurus agreed that the “qualitative world of sense perception arises from the motion of qualitatively neutral atoms. They believe that the immense qualitative variety results from the ‘jostling' of atoms...as they collide and bounce apart, and so, constantly form new groupings” (Jones 84). They believe it to be a mechanical process occurring completely by chance. Furthermore, although new groupings are constantly being formed, only the few that can survive are considered the

Apparatus: * water from a kettle * kettle * ruler * clamp * clamp stand * beaker * squash ball * thermometer Diagram: Method: § Collect all the equipment needed for this investigation. § Set
my opinion communication does change us in a way like for example backthen we did not have smart phones like we do nowadays. Back then they would have to send letters with messengers and it will take the message awhile for it to get there. Now we can carry a phone in our pocket. We can send messages in seconds across the world and make phone calls as well. Communication changed the whole world.2. Provide an example of each poetic device from any of the assigned poems.

Temperature and Squash Balls Experiment Introduction I am going to do an experiment on how high a squash ball bounces at different temperatures from the same height. Theory When a squash ball hits the wall the air molecules inside the ball heat up and make the ball warm. When they move faster they hit the rubber wall harder therefore makes the ball hotter. The reason why the ball moves faster is that when the ball hits the wall it causes friction and the molecules move faster
