Physics Of A Ping Pong Ball Drops From And The Height Effect On Independent And Dependent Variables

methods (as explained above), such as quickly rolling the ball around the edges, to be sure of no

For example a tennis ball will bounce higher than a soccer ball because it has more air pressure and it is harder.

Using a measuring tape on the wall each member of the lab group separately stood with either side against the tape and extended the arm beside the wall as high as possible. This height was recorded in centimeters. Next each lab member separately applied chalk to their fingertips, crouched down beside the tape on the wall, and jumped as high as they could while hitting the measuring tape at their highest point. This measurement was again recorded in centimeters. Then the height the lab member’s arm extended while standing was subtracted from the height when they jumped. This number denoted the vertical height jumped. For the jump height measurements a scatter plot was constructed. In order to do this, the data was again entered into excel, highlighted, insert chart and the first scatter plot choice was chosen. It was then that it was necessary to edit our axes and other parts of the graph. The x-axis was right-clicked and format axis was selected and fixed was selected and 20.0 was entered into the blank. Following this, a trend line was added to the graph by right clicking on a data point. A drop down popped up, and from there add trend line was selected from the choices.

The group first measured the masses of the four bouncy balls and then measured how high the ball bounced, being dropped at 20 inches, in room temperature and recorded the data. Then heated up water in a 250mL beaker using a hot plate to about 85-90 degrees Celsius, put the bouncy ball in a smaller beaker and held it in the water for five minutes, making sure not to get the ball wet, repeat this procedure for all four bouncy balls. After the five minutes were up, the masses of the balls were measured and then tested the ball to see if when the ball was heated, it might affect the height of the bounce. The results were recorded. Next, a 250mL beaker was filled up with water about half way and then put ice in the water to make it cool down to 5-10 degrees Celsius. A bouncy ball was then put in a smaller beaker and held the small beaker with the ball inside the ice water for five minutes, doing this for all four bouncy balls. After the time was up, the group again measured the mass and tested the height of the bounce and recorded the results. When dropping the ball to measure the height of the bounce, the ball was dropped from 20 inches for each trial in all three

On day one, butcher paper was put on the wall to record the measurements. A mark was put on the butcher paper at a maximum height of 86 inches. On day two the ball was measured at room temperature. Before the temperature was measured an air pressure gauge was used for the basketball to check the air pressure inside. On the third, fourth, and fifth days the steps were repeated. After all the trails were all finished the data was recorded visually and on paper.

A factor that affects the energy needed to bounce a basketball is what type of surface the bounced on.

The ball will sink to the bottom giving a number. You then subtract that number from the water (20ml) and that will give the actual volume of the ball.

For example, our group obtained a mass of 45.52 grams or 45,520 milligrams for the ball in station six. However, another group obtained a mass of 43.50 grams or 43,500 milligrams. This difference most likely occurred due to the fact that students did not fully wait to see if the two lines on the triple beam balance were exactly matched up. Through our eyes, it may seem like they are lined up perfectly, but in reality, there could be the slightest difference that we do not notice. While we measured the width of the table at station three, we noticed a difference in the measurement.

The purpose of this lab was to find out how the amount of time that has elapsed affect the position of the car away from the point of origin. Our hypothesis was if the time elapsed is longer, then the car is going to be further away from the point of origin. In this lab the independent variable-what you are changing is time. The dependent variable-what you are measuring is how far the car is from the point of origin after a certain amount of time (3 seconds, 6 seconds, and 9 seconds). The controls-things that stay the same throughout the whole lab is the car we used, the meter stick that we measured in centimeters with, and the 40 centimeters of tape that we used to mark the position of the car. Materials we used was a car, 40 centimeters of

After a bit of thinking, we realized that shapes that were a scale factor of another have the same number of bounces, so for this to work, you need to reduce the numbers as if they were a fraction. 9/6 would be reduced to 3/2. Using this, we were able to create a formula that works for everything as long as they are reduced. Here it is: N + X - 2.This works for all reduced

Basketball is a very high paced and a physical game. It is a sport where if a player makes a mistake it could be very costly or not a lot. There are a lot of different surfaces that could possibly affect the bounce of a basketball. (Ohman, Kyle) If basketball is played inside a gym the surface is most likely a hardwood floor. (Ohman, Kyle) Hardwood floors after time they age and get something called wet spots, and if you bounce the ball on that spot the bounce of the ball will die. There are hardwood, concrete, asphalt, concrete, multi purpose flooring, and sports tiles , but it is hard to know which is the best for playing a game of basketball. This experiment will prove which surface produces the highest bounce.

Measure the heights listed in the chart using a meter stick positioned with one end on the splatter paper and the other end measuring dropper height.

Will different gloves with different amounts of friction have an affect on the amount of times a football is caught? If more friction is used, the amount of passes caught will increase, and the amount of passes dropped will decrease when the catch rate is the function of the gloves being used. The independent variable of this experiment is the amount of friction of different gloves. The dependent variable will be the amount of times the football is caught after being thrown. The experimental control will be using no gloves to add friction, and measuring the amount of passes caught.

So we used a cup to count the number of the pennies. The independent variable in this experiment is the spaghetti strands whereas the dependent variable would be the number of pennies being added in the cup. The things that are held constant is the same cup, the same type of pennies, the type of spaghetti that is being used in this experiment, the placement of where the spaghettis should be placed, and the initial setup meaning the same table. First we started with one strand of spaghetti, and placed the cup with the string in the center of the spaghetti, and with that we constantly added pennies into the cup until the spaghetti strands breaks. We continued with this process by adding another strand each time.Everyone would not get the same exact results, but everyone should have gotten roughly the same pattern of proportionality. Not all of our bridges were constructed in the same manner, so our results would differ. The design of the bridge can largely affect the outcome of the data in this particular lab.Three important vocabulary words pertinent to this experiment are independent variable, dependent variable, and controlled variable.Then let me know these three words is very important for this lab.Then the design of the bridge was different in each group.Maybe my group have a little deviation.But it's ok, you still learn something from it! Nice

The more and more I look around I begin to see how physics are integrated into practically everything that we do. These things would surely go unnoticed without making a conscious effort to notice them. For example simple things like riding a bike, or driving a car, or playing catch with a son or daughter. Just as these activities are loaded with elements of physics, sports are also, especially basketball. Physics play a part in every aspect of the game, from dribbling, passing, and shooting, to things as simple as setting a screen. First we should take a look at the elements of dribbling.
