Bouncy Temperature Experiment

Conservation of Energy Lab: Poppers Part 1. The problem addressed in this lab is that of whether conservation of energy can be applied to “real-world” trials to calculate predictions. My group approached the popper lab by testing the height of a steel ball when launched from the popper and using those observations to calculate predictions for the heights of other balls of different masses. The values we chose to collect were the initial height, initial velocity, height at its peak, velocity at its peak, and the “change in length” of the popper (really, the height of the popper). We assumed there was no air resistance or other frictional forces on the ball.

Hold one ball beside the top of the meter stick so it does not touch. Drop the ball. Have your partner record the height of the first bounce.

So the higher the ruler is the more potential energy it would be. As the marble rolled down the ruler, its kinetic energy (553334.91 J) was also increasing. The reason is because velocity and mass are part of what makes kinetic Energy. The faster the speed and the heavier mass caused more kinetic energy to be present. The potential energy of the marble when it was on the ramp was converted to kinetic energy as it rolled down.

In the first experiment, “ How does mass affect your game?” it shows that the data on “Ball- Mass 3” that the 10 pound bowling ball had the highest kinetic energy of 27(J), the greatest velocity (m/s) of 3.42, and in average it produced 4 bowling points. According to the data, on “ Ball- Mass 1” the 11 pound ball got an average velocity (m/s) of 3.14, the kinetic energy of 24 (J), and the average bowling points of 3. On the other hand, the evidence shows that the 12 pound bowling ball in “ Ball- Mass 2” has the velocity (m/s) of 3.12, the kinetic energy of 23 (J), and the average bowling points of 4 . Concluding that in my Game 1 the velocity of the masses of the bowling balls decreased when the bowling balls were heavier and that the kinetic energy was lower as the mass increased in the bowling balls.

2. The ball contains kinetic energy while in motion near the bottom of its path.

Problem statement: As a mother of two sons that are constantly bouncing a basketball around the house, I wonder if the basketball is bouncy on different surfaces. If the ball is dropped at the same height and same way on different types of surfaces, how many times will it bounce? Literature Review: There are different types of balls and different studies done about their use. For this experiment, we will focus on a basketball and how many times it will bounce on different kinds of surfaces.

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

Our egg drop was designed with many strategies in mind. One of them was to build our design with as many triangles as possible due to the triangle being the strongest geometric shape due to their ability to distribute force evenly to all three sides. This would spread the force off the impact on the floor throughout the structure making it when it fell no one point would get the full blow of the impact. Another tactic used when building our structure was trying to make it symmetrical. So that if it rolled while falling there would be no weak points for the structure to fall onto. Another tactic used when building the design was building out around the egg so that when dropped the structure would bounce and the force

The weight of the marble in the container will cause the elevated side of the seesaw to lower, and the other side to be lighter and elevate, which is mechanical energy. The mechanical energy is in its potential form when the seesaw isn’t moving, and when it is moving then it is in its kinetic form. The other side of the seesaw has an object, which when elevated will hit a platform, which has a marble placed on top of it. When the platform receives enough force to be raised, then the marble will roll down the slanted platform, which is gravitational energy. The gravitational energy is in its potential form when the marble is on the platform, and when the marble is rolling down the slanted platform, then it is in its kinetic form. The rolling marble will hit a domino and this will cause the domino to fall and hit another domino, which is gravitational energy, and this chain reaction will stop when the last domino has fallen. The gravitational energy is in its potential form when the dominoes are standing, and when the dominoes are falling,

The ball uses this kinetic energy to move up the usually 6 to 7 degree incline to the top of the playing field. The kinetic

The aim of this report is to analyse my overhand volleyball serve from a biomechanical perspective and compare it to an elite athlete’s overhand volleyball serve. Biomechanics is the sport science field that applies the laws of mechanics and physics to human performance, in order to gain a greater understanding of performance in athletic events through modelling, simulation and measurement. It is also necessary to have a good understanding of the application of physics to sport. In volleyball the applications of summation of forces, projectile motion and balance and stability have a major influence on the success and accuracy of an overhead serve.

This then makes contact with the ball and some momentum is being transferred into the ball where it begins its flight path. - Stability and Balance - The front foot takes a step towards the target which then increases the size of the base support. So as you execute the shot, the center of gravity still remains within the base of support keeping you stable and balanced with the execution phase. -

(2) Any lesser height, not less than eight inches, resulting in a drop contact velocity equal to the greatest probable sinking speed likely to occur at ground contact in normal power­off landings.

Physics of Soccer, 1). Therefore, a massive object will need more force to attain the same

Depending on the height from which the bowler drops the bowling ball, the ball will have a certain amount of potential energy. If the bowler bowls with a straight ball, the potential energy of the ball will not affect their game very much. It will, however, draw attention to the bowler when
