35-Gram Ping-Pong Ball

In light of our final exam, the chuck a duck project, we are to learn about projectiles, trajectory, and the factors that affect these things.

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.

The solid ball was typically used against forts and other artillery pieces. The grape shot and canister shot were utilized as anti-personnel munitions. The Garrison Cannon used three different types of shells; hot shot, chain shot and bar shot. Hot shots were cannonballs that were heated until they were glowing red and then fired at ships to set them ablaze. Chain shot and bar shot consisted of two cannon balls connected by either a chain or bar. They were designed to destroy ships rigging. The mortar used only one type of shell, the bomb. The bomb was a hollow shell that was filled with black powder and had a fuse. The howitzer utilized hollow shot and anti-personnel munitions.

In the hypothesis test we determined the null will be rejected based on the p-value (0.01) which is less than alpha level (.05) and if a bell curve was created the t-stat (2.53) and t-critical (1.67) would support the decision. The information from the collected data shows UniDun ball cannot be driven further than the SFballs.

Impatience is a virtue… or something like that I think. Think of driving behind that person on I-70 going twenty miles under the speed limit. We’ve all got someplace to be, and there’s always going to be that one thing which just seems like it’s going slower than it should be to get there. In this case it’s the New Year’s Eve Ball and it’s atrociously slow decent, which could even be questioned as a “drop.” I find it slow and fairly anticlimactic as it falls, and agree with the author that maybe we could speed things up a bit.

Kamryn and I shot our rocket three times the first time we shot our rocket, and it went the highest. The second time we shot our rocket, it went a little bit high but it did not go as high as it did the first time. The last time we shot our rocket, we took our fins off and it shot horribly. The first time the fins were on good, the second

Another source of error that could have happened would be failure to account for a factor. Since the picture was taken outside, multiple factors could have affected the structure of the cheerleaders. An example would be if the ground was uneven in that area. This would affect the calculations because we are finding the vectors at a straight horizontal line. Another example would be wind because it would have the same effect. Although in our current situation we wouldn’t be expected to determine all of these factors, a way to prevent the error from happening would be to brainstorm possibilities that might have an undesired effect. From there we could determine a way to keep those factors constant, or a way to compensate for them in the

When dropping a ball at a specific height would the ball return to its original height after it rebounds? When you drop a jumpy ball, why doesn’t it come back to its normal height? Is there something do with the loss of energy stored in the ball? In order to find out the answers to these questions, First you need to explore what types of energies are stored in an object, what happens when the ball is bouncing and what energy law it follows. Also, you need to determine how to use the laws for your

By using a 1 meter ruler to measure the bounce height in centimeters. Video footage will also be utilised to measure the bounce correctly by watching the film in slow motion.

“Whoosh!” went the marshmallow as it flung out of the catapult and through the air. In this paragraph I will explain three main processes we went through while doing our catapult project. First, we built catapults out of popsicle sticks and rubber bands, this process was hard and took a while. We had to wrap the rubber bands around each popsicle stick to connect them, then we had to hot glue a cap to the top to hold the marshmallow that we would launch. Next, when the catapult was finally built we were ready to start the tests. We first calculated the distance the marshmallow would go when we launched it using one rubber band, then two, and then three. I noticed that with one rubber band the marshmallow didn’t go very far, then with two rubber bands it seemed to go three times as far as one. Lastly, we tested the accuracy of our catapult.

The difference I recevied in my launch was the object. The weight and size of the object changed the distance of the overall measurments. Since the starburst was small and an didn't weight much it went further and faster. With the marshmellow the distance didn't reach a maxium of 20 feet. Since the weight and size of the marshmellow was different and larger the distance of the object wouldn't go far. The comparison of both object wouldn't be even, only becuase of size.

Due to the density of the Dead Sea Water, Ocean Water, and DI Water being lower the the calculated density of the golf ball it is hypothesized that the golf ball will sink in all three water samples. This hypothesis was reach based on the ranged of the water sample desity being from .8452 g/mL to 1.005 g/mL while the density of the golf ball is 3.779 g/ mL.After completing the experiment the hypothesis was found to be incorrect. The experiment resulted in the golf ball sinking in two water samples and floating in one water sample. The two most translucent water samples, Ocean Water and DI Water, with densities of .8585 g/mL and .8452 g/ mL were the water samples the golf ball sunk in. The golf ball floated in the least translucent water

Figure 1 below depicts a snap shot of the compact and physics-ridden entity known as a golf swing. Taken at my home in Olympia, WA, this picture was taken moments before the impact between my driver and the Titleist Pro V1 golf ball. The game of golf is riddled with physics concepts governing everything from the power generated in the swing, to every impact with the ball, to even the motion of the ball in the air and on the ground. Everything is governed by and can be explained by physics concepts. However, this paper will focus on the impact of the clubface and the ball (governed by Newtonian physics) and then its subsequent flight in the air as a projectile. We will look at both the first and second laws that Isaac Newton proposed as well as the resulting equations and concepts that come into effect when the ball is launched. The paper will conclude with a brief aside on the history surrounding the golf ball and its evolution, and subsequently why (in terms of physics) the golf ball embodies a very unique and well-known physical form.

The goal of the fling machine was to launch a ping-pong ball around 10 meters into a circular trashcan. In this project my partner made a rough idea of how she wanted it to work and brought it to school. After that we all tested and modified the machine to work to the specifications of the rules of the project. we ended up with a very powerful machine that wasn't accurate. It would launch the ball at the ground and we didn't make it in the trashcan even

Several systematic occurred in this experiment, but the most important one would have been the fact that the air hockey table was not completely level. This impacted upon the experiment in two ways. In the first experiment where the red puck is initially stationary, as the table was not level it moved around before the black puck collided with it. To overcome this the red puck had to be held in place and as mentioned before this would have provided and external force acting upon the puck. The unevenness of the air hockey table also meant that there was a possibility of friction acting on the pucks while they were moving. In the third collision with the Velcro another systematic error occurred. When the two pucks collided and stuck together they did not continue straight, instead they rotated. This is not linear momentum but rather it is angular momentum. This is reflected in the results as the magnitude of the initial and final momentum of the system is equal, but the
