Different Types Of Balls Lab Report

Baseball is an interesting game that is extraordinarily enjoyable to play. This task is about comprehension the material science of a couple key parts of this game. One may ask what material science could need to do with baseball? Like most games baseball includes physical movement. Baseball incorporates each of the three planes of movement through tossing, hitting, and handling. The greater part of the traditional laws of mechanics can be connected to comprehend the material science of this amusement.

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

In football the force of impact can be dangerous. Helmets are constructed to protect the brains of the players. Without this protection the player will receive major damage from the impact of the force. In this lab, students will construct a device that will protect an egg from the impact force from the drop. The egg acts as a substitute for the brain and the device is the “helmet” for the egg. The independent variable of this experiment is the trials; the dependent variables of this experiment are time and velocity. By using the laws of physics, students will construct an efficient device that will protect the egg from the harsh impact of force.

For example a tennis ball will bounce higher than a soccer ball because it has more air pressure and it is harder.

The ball now has kinetic energy. Kinetic energy like momentum in that it comes from the mass of the object and its velocity. Kinetic energy was transferred from the plunger to the ball just like momentum was but only if the collision was elastic. During and elastic collision kinetic energy is conserved. The balls kinetic energy is half of its momentum squared. This means the balls momentum is its mass multiplied by velocity, and then it is squared and divided by two. If the velocity or speed of the ball is reduced by one half then the overall kinetic energy is reduced by a factor of four (Kirkpatrick and Wheeler p.106)

Section Heading: The reason I think the golf ball will go the farthest is because it has the most density and density means “to have the degree of compactness of a substance.”I believe the tennis ball will go the second farthest because it has almost little density and it has no core at all and it's hollow.When the ball is hit with the most density it will give it the weight and power to travel great distance but unless the ball has to much weight it won’t go far.The baseball has the least greatest density so I gathered information

2. The ball contains kinetic energy while in motion near the bottom of its path.

Crumple zones are designed to absorb the energy from the impact during a traffic collision by controlled deformation. This energy is much greater than is commonly realized. A 2,000 kg (4,409 lb) car travelling at 60 km/h (37 mph) (16.7 m/s), before crashing into a thick concrete wall, is subject to the same impact force as a front-down drop from a height of 14.2 m (47 ft) crashing on to a solid concrete surface. Increasing that speed by 50% to 90 km/h (56 mph) (25 m/s) compares to a fall from 32 m (105 ft) - an increase of 125%. This is because the stored kinetic energy (E) is given by E = (1/2) mass × speed squared. It increases by the square of the impact velocity.

Momentum is the mass of an object times it’s velocity. The velocity of an object would be it’s rate and change of direction. A collision occurs when two or more objects collide with each other. This causes the kinetic energy, the energy of motion, to be transferred

There is a dark cloud hanging over the world of contact sports and it is growing at an alarming rate. With the size and speed of today’s athletes, the sports of football and hockey have become more exciting, fast paced, wide open, and fun to watch. However, there is another consequence of these ever growing athletes on their sports. They have made the collisions in them increasingly more violent. The velocity that these athletes hurl themselves through the air has created an atmosphere that could not have been imagined when these sports were created. Although the athletes’ bodies have become

Our Rube Goldberg machine starts with a ball at the top of a ramp with gravitational potential energy. As it rolls down the ramp, its gravitational potential energy turns into kinetic energy. Once the ball gets to the bottom of the ramp, the ball has no gravitational potential energy only kinetic energy. The ball continues to roll because it has momentum until it hits a domino line. The ball transfers its momentum to the

The results from this experiment show that the elasticity of a ball does not affect its bounce height. The golf ball was not as elastic as the tennis ball, but its results were much higher than that of the tennis ball. The results in this experiment tell us that while elasticity does have some affect on the bounce height of the ball, another variable is altering their bounce height. The information gathered from the table and the graph did not support the

In the experiment there were flaws like human error in how hard the ball was pushed. In the first trial for 5 meters I pushed the volleyball less than the basketball so that is why there is a massive difference between the volleyball and the basketball. Another would be perception.

The goal behind this experiment was to estimate the distance a ball would travel after it falls a certain distance and bounces off a metal plate which has an angle of 45 degrees. To find this we had to take the basic equations for kinematics which are (1/2)at2=x and v=v0+at and combine them to make an equation that will help us solve for the distance the ball will travel after hitting the bounce plate. The equation came out to be R=g*(sqrt(2)/sqrt(g))*(sqrt(H)*sqrt(h)), as that g is acceleration of gravity, h is the height of bounce plate, and H is the height of where the ball will be dropped. After completing this experiment the result was that the standard deviation was +/- 2.3 cmfrom the

An elastic collision is a collision in which kinetic energy is conserved, such as when a running back is hit so hard by the opposing team’s linebacker on a lead-draw play up the middle that the ball is forced out of his arms. The fumbled ball then hits the turf and because of the elasticity of the collision it bounces back up. Unlike an elastic collision, an inelastic collision does not conserve the kinetic energy of the colliding objects (Kirkpatrick & Wheeler 134). An example of an inelastic collision might be when a player catches the ball (if he catches the ball) and the momentum of the ball is completely stopped. However it is important to realize in this study of physics that a
