Energy of a Tossed Ball

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.

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.

Which tended to be higher, the initial potential energy or the final kinetic energy? Why might this be?

In physics, an object’s kinetic energy (Energy in motion) is equal to work multiplied by rearrangement. In softball terms, a pitch’s velocity is equal to the force utilized by the pitcher, times the distance the ball travels before release. This explains is why softball pitchers use a windmill wind up because by moving the ball in a circle, it travels a greater distance than if the pitcher moved the ball straight back and then straight ahead. During a windmill wind up, the ball speeds up until it leaves the pitcher’s hand, after which, gravity and wind resistance begin to reduce its velocity.

Since the range in the gain in kinetic energy is greater than the range in the loss of gravitational potential energy, unlike the other four trials, the tautness of the string attached to the ceiling is another plausible error. In trial 5, the string not being tight explains why the gain in kinetic friction was slightly greater than the loss of potential energy. Since the string wasn’t taut, the ball, after the ticker tape had burned, needed to drop and then go on its path to the blade; as a result, the pool ball started with a gain in kinetic

All ages in our lifetime have played with some type of ball rather it is a softball, tennis ball or soccer ball any kind of ball you can think is a hollow ball made out of rubber. In order to raise the temperature in the ball to increase the bounces you have to give it a couple of practices to warm the certain object. In this experiment there was a small rubber ball, metal pole, meter sticks and a stopwatch. The goal of this objective was bounce the ball ten times and to record the time of how long the ball would bounce for in each set of data each section of how many times to bounces the ball to get a better outcome then you did the first time by trying different ways rather its using a step stole to get better height or using a measuring

In general, there are two types of energy experienced in this experience; potential and kinetic. Potential energy is energy that is stored in an object. (i.e. club about to hit the ball.) Kinetic energy is energy of motion. (i.e. the club after its been released and the ball in motion after it being hit. The formula behind these are that KE= (1/2)mv2 and PEg = mgh.3

In conclusion, the investigation proved that the energy of the ball at impact is proportional to the crater’s diameter on sand.

The total momentum and total kinetic energy before and after do not match up because the final momentum and kinetic energy is smaller in the straight on collision and larger in the nearly straight on and glancing blow. For kinetic energy to be lost like in the straight on collision means that the kinetic energy was transformed into another type of energy like sound because in real life when the balls collide, a sound can be heard during the collision. However for kinetic energy to be gained does not make sense, meaning something was wrong with the apparatus or calculations. Part of the results do reflect the theory since for the straight on collision, the most of the velocity from the blue ball is transferred to the red ball. And in the nearly straight collision and glancing blow both balls have

The aim of the investigation was to determine the bounce efficiency of a tennis ball at varying heights and it was hypothesised that as the drop height was increased, so too will the bounce height due to the extra gravitational potential energy being added with an increase of drop height. The findings indicated subtle changes occur in the bounce efficiency of the tennis ball from 91%, but with an overall decline in the chosen linear trend line. The results of the experiment support the hypothesis that as drop height increases, so too will the bounce height due to an increase in gravitational potential energy, however the bounce efficiency remained relatively

From equation 5 we found that the velocity of the ball after impact is given by:

Step 5: The cup that the marbles roll in comes up and hits a golf ball that is on a tilted side and falls on a meter stick. The golf ball has potential energy sitting on the side. The speed of the cup as to be perfect or we will miss the golf ball. The mass doesn't really matter in this step. There was rolling friction will the golf ball rolling off the edge.

Therefore, the initial kinetic energy and the final potential energy should be equivalent. Knowing this, we can solve for the height the ball should have reached knowing the initial kinetic energy.
