Ball Bounces Lab Report

1007 Words5 Pages

TASK:
When a ball is dropped from a height, it loses some of its energy and each bounce gets shorter. Your investigation will determine the effect of original drop height on bounce height. From this, energy loss can be calculated between bounces. As different groups will be using different balls, you will be able to compare energy loss with different balls. You are required to present your findings in a lab report format, which has been detailed below. The lab report must be typed.

The task to understand the reasoning for the ball drop and/or bounce. The force of the ball hitting the ground puts a force back onto the ball, causing it to bounce. Balls are made of an elastic material like rubber which rubber was designed to bounce or reflect pressure. Because the ball is …show more content…

Analysis & Discussion
Answer the following questions:
• Why did these results occur?
• Analyse the data. Are there any patterns or trends in the data?
• What is the relationship between the variables being investigated?
• Is the hypothesis supported by the data?
• Use science concepts to explain the patterns, trends or relationships identified in the data.
• Compare the results to another group: are the results of the other group the same or different? If there are differences, suggest why?

These results occurred lower than the original ball drop because the gravitational force pulled it towards the ground which leaves the first bounce lower than the drop and every bounce it gets lower until it is at a still motion on the ground because of the gravitational force. The patterns in the data is, that if there is less mass the ball will bounce higher because the gravitational potential energy is lower which allows the balls elastic energy to be used to its maximum. The hypothesis is supported by the data because when the ball was increased in height the bounce was higher. 9. Conclusion
Answer the following questions:
• Was the outcome different from the prediction?

    If no, t my results could possibly be an out lier if we were to graph and look at the class data as a whole. One factor that could effect results would be the environment. Meaning the other people (students) around you during your trials. If one student was walking extremely fast in comparison to your normal pace you might start to walk faster subconsciously and be influenced by them. Another factor that could influence the results is not throwing the ball properly in condition four and just passing it to the other hand instead.

    The experiment overall was nicely conducted, and results were found through the information gathered. The dependent variable was established very quickly; furthermore, we can find the dependent variable was whether the athletes played a contact sport or a sport like baseball, where most concussions come from being hit by the ball. The independent variable is the number of concussions the test subjects obtained. Ultimately they could not control how many concussions each individual obtained but they controlled which individuals were chosen and what test were ran. The results that ran throughout the whole experiment was an overall success, the results show that multiple compared to single occurring concussions do not have an effect on P3 suppression.

    PACE TECHNICAL PAPER ROUGH DRAFT This experiment was conducted in an attempt to have wooden baseball bats brought back to NCAA and high school and children’s leagues, too. The experiment idea was to set up a pendulum where the bat swung down and hit the ball in the same spot every time. Then I measured where the ball hit the ground.

    How does temperature affect the bounce of a tennis ball My science fair project is about tennis balls and temperature. I chose this topic because I am interested in how temperature affects how high a tennis ball bounces. When the ball hits the floor it expands and when it comes up then it comes back up it contrasts. My question that is going to be answered is,how does temperature affect the bounce of a tennis ball?

  • The Role Of Concussions In Sports

    As has been discussed previously, the role of concussive injuries in sport is currently controversial and subject to much discussion. It is notable that there are specific sports related attitudes to concussion as well as more general mechanistic approaches. The following section will seek to address these points in more detail utilising published literature. The tern concussion, also known as a mild traumatic brain injury, is derived from the Latin concussus which means to shake violently (Cantu, 1996).

  • How Do Different Surfaces Affect How High A Basketball Bounces

    964 Words  | 4 Pages

    Yes height does affect how high a basketball will bounce. For example if you drop a basketball from 4 feet it will bounce higher than if you bounce it from 1 foot. This happens because of acceleration. When you bounce a ball from somewhere high it gets more acceleration and speed and therefore makes it bounce higher than if it was from a lower height. This is because as the ball is falling it is picking up speed which gives it more kinetic energy.

    On January 18, 2015, the New England Patriots and the Indianapolis Colts played in the AFC Championship game in a chilly temperature of 51°F. The Patriots were accused of cheating when, at half time, 11 of their 12 game balls were found to be two pounds psi less than the regulation size of 12.5 to 13.5 psi. Although the balls are gauged 2 hours and 15 minutes prior to the game, they are returned to the teams before the game started. Based on extensive research and data, the Patriots’ balls were tampered with prior to the game. Objects with gaseous interiors have a tendency to decrease in pressure when exposed to cold temperatures but the decrease will only be minor.

    Future Experimenters might test throwing the ball at different speeds through the football passing machine. This may show something that could not be seen in the data from this experiment. In addition to receiving different data and statistics, experimenters may find outliers and anomalies that were not found in this set of data. Only testing at the one speed on the football passing machine may have hid statistical curves that could only be seen by changing the speed of the machine. By testing different speeds, it may show that normal regulation football will not actually travel the farthest.

    My project is about how temperature and air pressure affect the distance a football can be thrown. When the air is warmer the molecules move faster and spread apart, therefore making the air pressure lower and making the ball lighter. But when the air is cooler the molecules move slower and move closer together, making the air pressure higher making the ball

    As the marble slides down the first drop it will lose much of its potential energy corresponding to the loss of height. The marble subsequently gains kinetic energy – kinetic energy is contingent to the mass and the velocity of an object. The marble speeds up as it loses height, consequently, their potential energy is transformed into kinetic energy. Newton’s Second Law states that an object’s net external force is equal to its mass times its acceleration; simply, the acceleration is proportional to the force applied and also the mass of the object.

    In this science fair project, I tested if the difference in gender or age has a strong effect on the stroop test in order to understand the stroop effect more in depth. The results shown that adults understood the stroop effect better than other groups of people. I hypothesised that the difference in gender and age had a strong effect on the stroop test and that Kids would understand the stroop test better than adults. The difference in age and gender did affect the outcome of this experiment, however it was the adults that understood the stroop effect the best because of sharp eyesight. In this activity, the amount of time it took for each person to complete the stroop test was in relation to the people I chose to participate in the stroop
