Physics was observed during a DHS girls lacrosse game by Newton’s Laws and in free-fall. Newton’s Laws consist of 3 different laws, the law of inertia, F=ma, and action-reaction forces. Free-fall was observed in the game when the lacrosse ball falls, and only gravity acts upon it. All in all, Newton’s Laws and free-fall was portrayed during the lacrosse game.
My question looks at how gravity, and the weight and size of different balls affects how long it takes to hit the ground. The balls I choose was the American football, golf ball, baseball, and tennis ball. As learned in this experiment, weight and size affect how fast the ball drop because gravity will cause the heavy ball to drop faster. This means that the heavier ball should fall faster, while the lighter ball should fall slower. I choose this topic because I want to know if ball sizes influence how fast the ball will hit the ground.
Based on our observations above, we have come to the conclusion that our hypothesis is wrong. Our hypothesis said that the heavier object would fall to the ground faster than the lighter object but, our observations were proved wrong. The metal ruler and the plastic ruler fell first for about 20% each but, the two objects fell on the ground at the same time for around 60% out of the 60 trials. The hypothesis is not supported because the two objects fell at the same time for more than half of the 50 trials which means that our hypothesis is wrong. It seems like both objects have the same gravity pull and the mass and weight don’t affect the results.
The application of force in the delivery of a pitch directly influences its speed and movement. By understanding how different forces act on the ball during its release, we gain insight into the relationship between force and speed (Newton's Laws of Motion, 2023). In application of the previously discussed forces of pitching lies the Magnus effect. The Magnus effect is responsible for the spinning of the ball in the air, but how? When the ball is traveling through the air from a pitch, one side is traveling in the direction of the air flow, while the other is traveling in opposition to it.
The null hypothesis of this research is that the gases (helium, nitrogen, argon, and CO2) will have no effect on the football hang time. This study’s alternate hypothesis is if a football is filled with a gas lighter than air (helium and nitrogen), then the football will have a longer hang time; and if a football is filled with a gas heavier than air (argon and CO2), then the football will have a shorter hang time. Since the first experiment results were nullified because of an error in the PSI of the football, the second experiment results led the researcher to reject the null hypothesis. There is enough evidence to support that footballs filled with gases lighter than air will have a longer hang time and footballs filled with gas heavier than air will have a shorter hang time. The reason to make this claim is that the researcher found that gases lighter than air (helium and nitrogen) had longer mean hang times and gases heavier than air had shorter mean hang times in Table 2 and because of the error bars in Graph 2, it showed significant differences between the means.
First, when the golf club is to hit the golf ball, all energy is stored as gravitational potential energy of golf club(Ep), so the total energy system before the golf club hits the ball is written as: ET = Ep(initial) = mgh As the club swings down, the gravitational potential energy is converted to the kinetic energy. And then when the club hits a golf ball, kintic energy of the club will be converted to the linear and rotational kinetic energy of the ball and some will be converted to heat and sound energy due to inelastic collision. In order to measure the gravitational potential energy, a golf club fell from the same height and the height reached after the collision was measured. The height difference between after the collision and before
In the data, one trend found was that as the ball became closer to the ground, it’s kinetic energy value went up and the GPE value went down. Also, when the ball went up, the value of kinetic energy became smaller and the value of GPE became greater. This is correct because when any object is close to the ground the kinetic energy is greater than the GPE and when the object is at it’s highest point the GPE is greater and the kinetic energy is less. Another trend was when the ball was at the very end or beginning the total energy was .5 off from the total energies of the points in the middle. This is an example of inherent error because there was no way for the LabQuest to get the exact point and motion, so the calculations were bound to be
Column1 Spring Constant(N/m) Orange 1416.809091 ±193 Light Blue 1387.899091 ±190 Green 1421.951364 ±193 Using that force to find the spring constant from the tweaked equation mentioned before. Conclusion This experiment confirms the relationship of the spring constant between the objects when projected with a certain field of force. Even with their difference in mass, each ball showed similar results when launched with 620 ±80N proving that spring constant has a relationship between if experimented properly.
We only used one material which was the weight in this experiment. The weight had a smooth surface which may have allowed it to slip easily compared to a material that has rougher sides. An object with a smoother surface has less friction and when gravity acts upon it, it will slide easily thus at a lower angle causing a low coefficient. Q5.
I decided to play racquetball with my father at the gym for this experiment. Racquetball is a competitive game where a group of players play tennis ball inside of a box, and they take turns hitting the ball with their racket onto the wall to travel towards the other players. I had an amazing time playing, and I learned a couple of interesting information about himself and I. During Labor Day weekend, I was spending quality time with my family in Pittsburgh, and one morning, I decided to play racquetball with my dad. This is because I would see if I 'm interested in it, and I knew that I needed to workout, since I haven 't in a while. I knew that he has been playing that sport for the longest time, and I have been greatly interested in
Chase Dahler Advanced LA 11 Mrs. Rasmusson May 10, 2023 Physics of Baseball Foley’s baseball coach Mr. Beier once said, ”Are you studying for a physics test? Well, then you had better be studying baseball.” Even though he had declared this as a disciplinary reprimand, it still holds weight as a somewhat truthful statement. Sports and physics are obviously directly correlated in terms of motion and force, but more than ever in the sport of baseball. Physics in baseball, whether watching or playing, revolves around the ball, the bat, and the transfer of energy.
Smart precautions and planning averts the Tennis injuries Some times of any year becomes all about Tennis - with the Australian Open, Wimbledon and other lead-up events grabbing our attention as the stars occupy our TV screens. The gruelling circumstances and the astounding amount of time spent by the players on court lead to unavoidable injuries. Tennis injuries are not only observed in the elite field, the sub-elite and recreational players are at the risk of injury owing to the elevated speed and racquet size, and the repetitious character of this sport. This leads to injuries in spots such as the elbow, shoulder, wrist, ankle, knee, hip, and spine. While the most identified tennis injury is 'Tennis Elbow ' - the actual incidence of
The rotational motion also known as spin affects the tennis balls trajectory when it travels through the air, as well as how it bounces. Players use rotational motion to their advantage because the spin of the ball affects their shot and makes it more difficult to return. When the tennis ball falls it initially gains speed or kinetic energy this is known as motion of energy. The ball falling velocity downward is influenced by gravity because without gravity the ball would never hit the ground it would go on forever. So when the ball reaches the ground it hits the surface that is at rest.
Physics Applied to Soccer Soccer. The most popular game in the world, and yet the most beautiful. This sport is known for its skill and its way of bringing people together. Though what most don’t know is that a great amount of physics can be applied to the game of futbol. From Newton’s Laws of Motion, to things such as friction and inertia, there is so much to learn from this sport.
Introduction In the lab “Gravity Demos,” the common objective is to learn more about gravity and the center of gravity by performing various experiments. The definition of gravity is an attraction between any objects that have mass. Every planet has a gravitational pull, for example, earth’s gravitational pull is 9.8 meters over seconds squared (9.8 m/s2). This means that a bowling ball and a feather would fall at the same speed and hit the ground at the same time if there wasn’t air resistance (a force that slows down objects that move through the air.)
