During the bounce test, the ball may have been released from different points. Although it was supposed to be released from its bottom, human error may have compromised the precision of this measurement. To improve the design of the bounce test, the ball’s bottom point should be marked, and the ball should always be released from there. During the ramp test, the ball may also have been released from different points. Although the ball was supposed to be placed on the ramp so that it would be released from the front, human error may also have compromised the precision of this measurement. In addition, human error may have caused unintentional and unnecessary force applied to the ball. To solve these design issues, a door should be made that holds the ball at a certain position for a fixed amount of time before the experimenter released the ball. During the catapult test, the ball may have been held back for an excessive amount of time. To resolve this experimental design issue, a fixed time to hold the ball back should be

Objective: Using a marble launcher, launch marbles from different angles with different forces to find the maximum height and the velocity as it leaves the launcher. Using different variables and results to determine how the different angles and amounts of force effect the variables. With this data show the effect the forces cause in 1-D and 2-D motion, as well as in the X and Y directions. This is done through kinematic equations and calculations.

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

9. The total energy is constant for most of the time until the ball is released and caught up and down in free fall, because extra force of the person actions changes the energy. The energy should remain constant because the kinetic and potential ratio energy

Our Rube Goldberg machine starts with a ball at the top of a ramp with gravitational potential energy. As it rolls down the ramp, its gravitational potential energy turns into kinetic energy. Once the ball gets to the bottom of the ramp, the ball has no gravitational potential energy only kinetic energy. The ball continues to roll because it has momentum until it hits a domino line. The ball transfers its momentum to the

Moving along, to the second experiment, “How does force affect your game?” concludes that using a 10 pound ball applying strong force provides a velocity (m/s) of 3.2, a result of 25 (J) for the kinetic energy, and 5 bowling points

So, the more potential energy there is, the more transformed into kinetic energy to help the ball go down the ramp and push the card. This shows that the height of the ramp and the mass of the marble is what determines how well the marble hits the index

In this experiment a basketball was used because of its size and was used in a controlled environment. For two of the out of the three trials in the experiment a freezer and refrigerator were used to cool the ball the temperatures. For one of the trials the ball was heated with a heater, the temperature for the heated ball was 111. The basketball was measured by a measuring tape that went by inches. The data chart found that the heated ball was the one that bounced the highest and the freezing ball was the lowest temperature bounce. The three variables of this experiment was independent, dependent, and control. The independent was the temperature of the basketball. The dependent was the height of the bounce. Finally, the control was the floor surface, the height of the drop and the basketball room temperature. The tools that the experiment needed was the thermometer to check the temperature of

For example, when the car had 3 weights on it and weighed 1,457.9 grams, the average acceleration was 0.4116 m/s². When the car did not have any weights on it and weighed 653.7 grams, the average acceleration was 0.8771 m/s², which is more than double the acceleration of the car had 3 weights on it. When an extra 804.2 grams of weight was added to the car, the acceleration decreased by 0.4655 m/s². The evidence provided by the experiment proves that the more mass the object has, the more the acceleration will decrease, showing the direct relation between both mass and acceleration.

Our Rube Goldberg machine starts out with a funnel at the top. Two marbles are placed into the funnel, which contain potential energy. When the marbles go through the funnel they have kinetic energy and enter a wheel and axle. Before the wheel and axle moves it has potential energy, but once the marbles fall into it the wheel contains kinetic energy. From the wheel and axle, the cup containing the marbles is knocked over and the balls fall into an inclined plane. At the top of the inclined plane the marbles have potential energy however once they roll down they have kinetic energy. The same transfer of potential to kinetic energy occurs when the marbles fall into the next inclined plane.

During the last lab, two properties were highlighted to facilitate the experiment. This lab had demonstrated the use of the properties of hydrates and the law of conservation of mass using hydrates. There were four differents experiment which were used to defined the final product. Hydrates being defined as compound were combined with water. Water had played a big role in some part of the experiment.

Topic: Newton’s Cradle IV: I will change the materials in between the balls and the density of each ball that transfers energy to the ball on the end. DV: I will measure the angle of the ball on the end at its maximum height. For my experiment, I will create Newton’s Cradle and change the density of each ball involved, and I will also place different materials between the balls. I will always keep the ball on the end of the chain the same density and mass.

The purpose of the lab is to collect data, then from the data determine the potential energy, spring constant, and the maximum velocity of the toy. The toy measured to be 0.055 kg, 0.06 m tall when standing and 0.04 m tall when pressed down. During the experiment, we determined that the average maximum height of the toy is 0.622 m. From this information, we determined, using the equation PE=mgh, that the potential energy of the toy was 0.313 Joules. Then, using the potential energy and the difference between the toy’s height when it's pressed down and when it's freely standing we determined the spring constant by using the equation PE=(1/2)kx^2.

The stiffness of the beam will depend upon the properties of the material used in its construction and the component geometry of the design of the beam.
