How The Mass And Angle Change The Range Of Projectile Results

The bessbug took 5 minutes and 47 seconds to reach 6 cm with 10 weights.

It’s no secret that sports are becoming more and more elite as the athletes that play them begin to utilize science to maximize their output. Baseball and softball are no exceptions to this phenomenon. As America’s pastime and two of the biggest college sports for each respective gender, ground is constantly being broken in order to discover new and improved techniques to put out the best players possible. One of the skills that has always been at forefront of refinement has been the swing; athletes want to hit balls faster, harder, and farther. In particular, the launch angle has become an increasingly popular topic of focus the the world of baseball and softball. Launch angle is defined by the MLB as, “the vertical angle at which the ball

Steps 1-3 were repeated in till three accurate drops were completed for one of the three shaped bladed rotocopters.

For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.

To find the momentum of the highest drop, the mass of the container with the egg inside it, 0.600 kg, was collected, and the final velocity of 15.0 m/s was calculated. This velocity was calculated by multiplying gravity by the time it took for the container to fall this distance. The final velocity and mass were then multiplied together to get the momentum, which is 9.00 kg m/s. Impulse is the change in an object 's momentum and can quantify the overall effect of a force acting over a specific time. To find the impulse for the highest drop, the value of the force exerted on the container was calculated by multiplying the mass with gravity, which equals 5.89 N. This force was then multiplied by the time it took for the drop, 1.53 s, which equalled an impulse of 9.01 Ns. The impulse and momentum is the same because, in a collision, an object experiences a force for a specific time interval that results in a change in momentum. The result of the force acting causes the object 's velocity to either change speed or direction. In conclusion, the impulse experienced by the object equals the change in momentum of the object, which can be seen in equation Ft = m Δ

Observation is the tool that practitioners use to obtain the necessary information that helps them to plan effectively for each child. Observations are considered to be an important part while working with the children. There are number of reasons why recorded observations are required.

Its material and light-weight allows air resistance and its spin to have significant effects on its motion when airborne. Air resistance is the result of the projectile’s leading surface colliding with air molecules, and it is affected by the velocity of the object and its cross-sectional area. Specifically, a higher velocity and greater cross-sectional area results in greater air resistance. Additionally, ping pong balls allow bounce quite high when they strike a surface.

After that came ping pong ball (ball 1) with a 1.03 meter rebound height, and tennis ball (ball 2) had the lowest rebound height with 1.02 meters. My data was accurate, because for every height, we had to drop the specific ball three times. If the member recording the rebound height didn’t get an accurate reading, the entire group would re-drop the ball until we did get an accurate measurement. By doing this, we mitigated errors before they occurred. After dropping the ball three times, the group would calculate the average rebound height. Then, we would compare the average rebound heights among different drop heights and different types of balls. An error that could have negatively affected the data, is a human error. Even though the group tried to be as accurate as possible, mistakes always happen. A measurement could have been read wrong, or a mistake in calculating the averages might have occurred. In the future to get rid of these problems completely, the lab could be done twice to insure accuracy and check for possible mistakes. For a future experiment, it could be tested how much power it takes to push down on the three balls for them to bounce 2 meters

My project is about how temperature and air pressure affect the distance a football can be thrown. When the air is warmer the molecules move faster and spread apart, therefore making the air pressure lower and making the ball lighter. But when the air is cooler the molecules move slower and move closer together, making the air pressure higher making the ball

the other side lengths and that is the number of rebounds.(EX. 10 - 1= 9)

With baseball being one of the most popular sports on the planet, many people are familiar with the different types of bats, which are wood and aluminum. Though many people argue the aluminum bat is better it rises the question, which is truly better, wood or aluminum? This papers will focus on the analysis of wood and aluminum bats.

Softball is a sport I have been playing since I was eight. Running the bases is something I have enjoyed about playing the game. With my experience with softball, it led me to question which size ball would travel the farthest. Thus, my experiment question is “Which size ball would travel the longest distance when thrown?”.

Analysis - To initially get the position vs time graph, the whiteboard ramped was marked every half meter and four time trials were done going to every mark. the times were then averaged and plotted on a graph. With each average time a velocity was calculated by distance/time and those were averaged to find the velocity (because the buggy was a constant speed there is only need for one velocity). With this, it turned out the slope of the position time graph was the velocity. If there was a non constant velocity, the derivative of the position time graph would yield the velocity for the specific time. From the velocity time graph, the total distance could be covered by using integrals. For example, to find the displacement from 1 second to three seconds, the equation 13v(t)dt would give the answer of -.684

Mr. Jackson, the commander should to appoint a Meal Card Command Officer (MCCO) as additional duty IAW AR 600-38. The newly appointed MCCO should bring a copy of the "Additional Duty Oder 's", DA Form 1687, and the commander 's assumption of command order 's to me. I will give him an inventory of all meal card books that are signed to his unit and assist the MCCO of what need to take place to get the unit within AR

The task to understand the reasoning for the ball drop and/or bounce. The force of the ball hitting the ground puts a force back onto the ball, causing it to bounce. Balls are made of an elastic material like rubber which rubber was designed to bounce or reflect pressure. Because the ball is
