Scientific Report Science Assessment Task Number 2 Tori Duckett – Year 10 How does temperature affect the bounciness of a bouncy ball? Written by Tori Duckett Abstract Temperature affects the bounciness on bouncy balls. The height of bouncy ball determines its bounce which link with the temperature and molecules inside of the balls. This investigation explores whether temperature affects the bounciness of a bouncy ball and its given height for each trial in the results. From this we are therefore determining whether room temperature, boiling water or freezing temperature affects this following experiment. To test this idea 3 bouncy balls were heated, frozen or kept a room temperature over the range of -18C to 100C. Heating was achieved by …show more content…
Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance. From this we can determine the heated molecules inside of a bouncy ball giving us its great effect on its given height when dropped at its designated height. A lower temperature will lead to a lower pressure. As the temperature decreases, gas molecules contract and move around more slowly with less energy. Thus, lower pressure leads to a lower bounce of the ball. This then lead onto room temperature, the molecules inside of the bouncy ball remain the same, as there has not been any temperature used to affect the bouncy ball. At impact, most of the kinetic energy is transferred to elastic energy in the ball and not to the floor. Some energy is also converted to other forms like temperature. These other forms of energy, are mostly losses and they are not recovered thus making the ball bounce back to a lower height. While the context of this investigation may be of primary interest to peers or of human activity, the investigation relates to the field of material science, where the question of temperature effect of bounciness on bouncy balls may be of high importance of other context, such as temperature in other forms of objects, physics etc. Aim To determine how temperature affects the bounciness of a bouncy …show more content…
From the graph we can see an existing relationship between both the factors. As the temperature increases the height that the ball bounces increases. From the best-fit line, we can see that the height of the ball bouncing will keep dropping as the temperature decreases. From the graph above, and the data analysis it can be concluded that my hypothesis was correct. It was earlier predicted that as the temperature would increase the height would also have a change in increase of the bounce of the bouncy ball. There is a confirmed relationship between the two variables and there is sufficient evidence to support the investigation. As the ball is kept in cold temperature, the particles inside the object come close together and thus become harder. When the ball is kept in hot temperatures, the particles inside the ball matter start to move faster and move apart from each other. This therefore makes the ball bounce a greater
As the temperature increases, the movements of molecules also increase. This is the kinetic theory. When the temperature is increased the particles gain more energy and therefore move around faster. This gives the particles more of a chance with other particles and with more force.
A characteristic property can help identify a substance. A characteristic property will never change even when the volume of a substance is varied. A characteristic property also does not change when a substance changes state in matter. A physical property cannot identify a substance. A physical property will change when the volume of a substance is varied. It can also change when the substance changes state in matter. For example, if the volume and mass of a substance changes then the physical appearance will also change. However, the density, which is a characteristic property, will not change at all. The boiling point of a substance is the temperature that a substance changes from a liquid to a gas. The boiling point of a substance is a characteristic property because the boiling point of a substance will never change even when the volume and mass changes. The only thing that will change is the time that it takes to reach that temperature. If the mass and volume of the substance is small, then it will take a small amount of time for the substance to reach the temperature. However if the mass and volume of the substance is larger, then it will take a longer time to reach the temperature. The purpose of this lab was to see if when the volume of a substance changes so does the boiling point.
I decided to use one type of ball, so the weight was constant. And the
The Physics of the Curve Ball Dad said that one of these days I would figure it out, but to this day I am still clueless. I have always been able to throw a decent curve ball; you don’t just throw 6 one hit games in your high school career without one. I have always wondered why and how the ball curves through the air, and it wasn’t until now that I have really had the chance to research a topic that has puzzled me for so long. I would bet that even pitchers in the “Big show” don’t know how or why, but they obviously have the talent and ability. I don’t know when the first curveball was thrown or who threw it, but there is a lot of controversy out there about whether or not the curveball really exists.

it means the force of the collision has excited waves or vibrations called modes. When the ball is hit at
Bouncing Ball Investigation This is an experiment to investigate bouncing balls and how they behave in different situations. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. The first independent variable that will be tested.
The data which was collected in Procedure A was able to produce a relatively straight line. Even though this did have few straying points, there was a positive correlation. This lab was able to support Newton’s Law of Heating and Cooling.

...ns. This is related to Gay –Lussac’s Law. This is because temperature is the same thing as kinetic energy, and as the energy rises, the particles within the substance start to rapidly collide with one another, and they exert increased pressure. This law is written out as: .
This warming and expansion helps to lower the density of the air. Temperature ranges can also affect how a player grips a baseball, depending on how sweaty their hands are or if their fingers and cold and numb. Warmer air can also hold more water vapor. But at the same temperature, air with a higher relative humidity will be less dense. This is because as the temperature increases, water vapor displaces the heavier gases in the troposphere and the density per unit volume decreases.
How does the air pressure inside a ball influence the bounce height/vertical motion of that ball?
Also, when we put the insulation cans in warn water the water heated up the can. And lastly, in the insulated can experiments, both cooling and heating, when the cans temperature was changed it in turn changed the air temperature
• An increase in the temperature of the system will increase the rate of reaction. Again, using the Maxwell-Boltzmann distribution diagram, we can see how the temperature affects the reaction rate by seeing that an increase in temperature increases the average amount of energy of the reacting particles, thus giving more particles sufficient energy to react.
Heat energy is transferred through three ways- conduction, convection and radiation. All three are able to transfer heat from one place to another based off of different principles however, are all three are connected by the physics of heat. Let’s start with heat- what exactly is heat? We can understand heat by knowing that “heat is a thermal energy that flows from the warmer areas to the cooler areas, and the thermal energy is the total of all kinetic energies within a given system.” (Soffar, 2015) Now, we can explore the means to which heat is transferred and how each of them occurs. Heat is transferred through conduction at the molecular level and in simple terms, the transfers occurs through physical contact. In conduction, “the substance
