Physics: Work, Power, Energy

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

The purpose of this experiment is to see how height affects distance and to see how adding additional height affects the distance that the ball travels. Also, to see how gravity pulls the ball down storing energy and releasing the energy as the ball hits the bottom of the ramp and to see the distance the ball travels after books are added.

This soccer science fair project serves to acquaint students with basic information on how the amount of air in a soccer ball can affect the distance it travels when kicked with a consistent force. The greater the air pressure in the ball, the farther it will travel when a force is applied. In the process of conducting the research, the student will learn that atmospheric pressure may also affect how far the ball will travel. The student will learn about the relationship between air pressure and friction: the lower the friction, the farther the ball will go. The student will learn about concepts like air pressure, gravitational force, compression and expansion of air molecules, potential energy and kinetic energy. This science fair experiment

The purpose for the students of the Energy of a Tossed Ball Lab involved learning how to measure the change in kinetic and potential energies as a ball moves in free fall. Since there is no frictional forces working on the ball the total energy will remain constant and the students will see how the total energy of the ball changes during free fall.

Are forth step was the basketball to be hit by the tennis ball and fall through a hoop. This step had potential and kinetic energy and force. The tennis ball used the force from the baseball to hit the basketball. The basketball was storing up potential energy while the rest of the machine was running. When the tennis ball hit the basketball the potential energy was released. As the basketball was falling through the hoop it had kinetic energy.

1) Once the simulation opens, click on ‘Show Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around.

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

The task that will be performed in the lab is a football snap toward a target. The subject will face way from the target, place their feet about shoulder length apart, place the ball between their feet, bend over and snap the ball through their legs to hit the target. For the experiment, the target is a wall. The wall is marked in increments of 20cm; a center space with five spaces above and below.

In this experiment we first tried to find an experimental value for g. This was done by dropping a golf ball below a sensor that would read and chart the position vs time graph and the velocity vs time graph. From this we could receive an equation and numbers that are useful in finding the velocity and acceleration of the ball in order to find the experimental g value. Then we did another experiment in which we would hold out a ruler between another person's index finger and thumb and then drop it, measuring how many centimeters it took for them to catch the ruler. Using this and an equation we could measure their reaction time.

In conclusion a basketball may look sample but it’s is very complex and can be very hard to manage. This project will prove for once and for all if basketballs bounce higher with or without helium. “Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.” stated britannica editor Erik Gregerson.

A 15 kg uniform disk of radius R = 0.25 m has a string wrapped around it, and a m = 3 kg weight is hanging on the string. The system of the weight and disk is released from rest.

An incline plane was constructed on the edge of a table at no particular angle. There was at least five centimeters between the edge of the table and the bottom of the inclined plane. A box was placed directly in front of the table to “catch” the ball that would eventually be rolled down the incline plane. Carbon and white paper (carbon side down) were taped down in the area where the ball would bounce, before bouncing into the box. After marking the ground directly below the plane with masking tape, the start line was marked close to the top of the inclined

One part of the experiment was to test four different object free falling from the same height and recording their time with a stopwatch and again with a photogate. The second part of the experiment was to the take one of the four object that had a acceleration nar 9.8 meter/second sq. and testing it 15 more time with different height. Material Needed Stopwatch, meter stick, photogate, pen, ball, water bottle, pill bottle, and ring stand.

By understanding the relationship between work, power and energy we can improve performance of a free throw. All these components of power, work and energy are present when the athlete is bending

There are many forms of energy. The types of energy that can affect the toy car are potential energy, kinetic energy, and work of friction. Potential is the energy of an object due to its position. Kinetic energy is the energy due to motion. Friction plays a part because it shows how much energy is needed for the car to move. All these energies are intertwined in the toy car.
