Elastic collision

On Monday July 1st 1956, Americans woke up to tune in their radios, channel in their T.V.’s, or unwrinkled their newspapers to horrific news. Gruesome headlines, and bewildered anchors spread the news that the unthinkable, and impossible happened the previous day. In the pristine and picturesque skies over the Grand Canyon in Arizona, tragedy struck in a way that would forever shock and change the world of aviation in ways never before imagined. Two airplanes collided unexpectedly in mid-air.…

assumption, there are 4 points where the energy loss occurs. 1. The air resistance when the golf club is swinging. 2. The air resistance when the ball is flying 3. At the pivot point, due to friction with the pivot 4. Energy loss due to an inelastic collision between the golf ball and the golf club In the assumption, I supposed that the air resistnace when golf club is swinging and the air resistance when the ball is flying are negligible. Because in the experiment, the distance travelled by the…

calculated exactly the initial momentum and kinetic energy, final momentum and kinetic energy, and percent of momentum and kinetic energy that was lost through these collisions. To calculate momentum we used the equation p_i=p_f which expands to m_1 v_1i+m_2 v_2i=m_1 v_1f+m_2 v_2f. We can say that our first hypothesis was accepted since in collisions 1 and 2 the total initial and final momentum was similar values. Subsequently, we used the equations 〖KE〗_i=1/2 m_1 v and 〖KE〗_f=1/2 m_2 v to find…

constant motion and create collisions that results in pressure. The theory is split up into four different postulates. Number one explains how gases are made up of tiny particles. To prove that those particles take up space, postulate #2 tells us that the particles collide with each other and those collisions make pressure. Pressure can either expand or shrink a flexible container, depending on how many particles are in that container. If there are more particles then more collisions will…

potentially energy, and then back to kinetic energy in the opposite direction the ball was originally going. According to the law of conservation of momentum, the sum of the momentum of both the bat and the ball have to be the same before and after the collision. So the faster the bat is swung, and the faster the ball is thrown, the more energy will be in the ball following contact from the bat, equaling a greater distance traveled and higher velocity off the…

Softball is a game enjoyed by millions of people around the world. The game is played on a diamond-shaped field that involves two teams of players. The teams are filled with players who pitch, hit, and field in order to get runs to score. While the sport is often just seen as a game of skill and strategy, there is also a deeply ingrained principle of physics in it. Understanding the physics behind the beloved game can help provide valuable insight into enhancing a player's abilities. When I was…

if a passenger was to get into an accident with no seatbelt their bodily harm from the collision becomes greater. To understand how passengers are thrown around we need to remember Newton’s first law; a body in motion will remain in motion until an external force acts on it. Air bags and seat belts lower your chances of dying in an automobile accident by forty-five percent. When an injury occurs from a collision the severity of the injury can be quantified in many different ways. One is using…

Bouncy balls bounce because the material of the ball is extremely elastic and can convert kinetic energy from falling into potential energy and back into kinetic energy again with little loss of momentum. They are used in many classrooms because they can easily demonstrate conservation of momentum through a highly elastic collision. Like many things made out of rubber, bouncy balls have very high elasticity, meaning they rapidly return to their resting state after being stretched or squashed. If…

This experiment, created by the students of the class, went relatively well. In this lab, we teste the theory of the conservation of energy. The kinetic energy at the bottom of the ramp should equal the potential energy at the top of the ramp without regard to the path taken. Thus, for method 1, the equations for kinetic energy (1/2mv²) and potential gravitational energy (U_g=mgh) were used. For the second method, the concepts and formulas for constant acceleration was used in conjunction with…

would be harder to stop than a small car. This is as, the momentum would be greater in the larger car. A collision describes the process in which two or more objects exert large forces on each other. Stopping time refers to the thinking and braking distance. Impulse describes the change in momentum, impulse = force X time. In collisions, momentum causes 'Inelastic Collisions ' and 'Elastic Collisions. ' Inelastic occurs when the total kinetic energy changes, but the momentum remains the same.…
