The Physics of the High Jump
The world consists of many phenomena. Some of them are mysteries to us as human beings, while many others can be explained. Progressively over the centuries, science has helped us to better understand the spectacular things that physically affect the human race and the earth. Almost every single thing that deals with the physical aspect of our existence can now be explained through physics, which in turn helps us to better understand our surrounding environment. Where I have always been involved in sports, I am very interested in the specific physics that each sport consists of. One such sport that fascinates me is the high jump, and for this reason I am going to delve into the physics of the high jump and break it down to explain the different laws and physics that encompass it. The high jump can be broken down into three stages: the run up phase or approach, the take off phase, and the flight or bar clearance phase. By understanding these three stages and the different laws of physics that make them up, one will have a much greater understanding of the high jump and its mechanics. In order to begin this analysis, I need to start with the very first stage of the high jump, which is the approach or run up phase.
The run up phase begins with the jumper standing up vertically, in position to begin running, about ten strides away from the bar that is to be cleared. According to professors Jesus Dapena and Alexander P. Willmott of the department of Kinesiology, from Indiana University,“[the] run-up serves as a preparation for the takeoff phase, the most important phase of the jump”(2). The run up phase can be broken down into several parts. The first part of the run up phase generally follows a straight-...

The high jump may not be a spectacular phenomena or even a mystery to many people, but it doesn’t change the fact that it is governed by many principles of physics. By understanding the physics that make up the high jump, one can obtain a totally new understanding of the mechanics of this incredible sport, and in doing so can acquire an appreciation for the principles of physics that govern our earth and us as a human race.

- Explains that the j curve of the approach is important to the high jump for several reasons.
- Explains that the centripetal force achieved with this lean helps the jumper stay in his or her "circular path" and not continue in a straight line, which would result in knocking off the bar.
- Explains that it is difficult to distinguish between the final phase of the j curve and the take off phase because they both work hand in hand.
- Explains newton's third law of motion plays a big factor during the take off phase. the hamstring in the jumper’s leg experiences something that coach santos of the united states olympic team calls, "stretch reflex."
- Explains that the vertical velocity of the jumper's center of mass, which is initially close to zero, will change to a large upward horizontal velocity.
- Explains how a jumper brings his or her arms back and swings them in stride during the last step of the run up phase just before jumping.
- Explains the importance of a knee drive during the take off phase. it helps to apply more force to the ground in conjunction with the swinging of one's arms.
- Explains that the total angular momentum is achieved by the jumper during the first two phases of the high jump.
- Explains how the jumper's body continues to rotate, "on a horizontal plane," as the body is continuing in the circular path.
- Explains that the forward somersaulting angular momentum is a result of the high jumper planting his or her foot in front of their body during the take off phase.
- Explains that the somersaulting angular momentum occurs at the same time as the body of the jumper is experiencing the lateral momentum.
- Explains that the twisting somersault rotation leads to the bar clearance phase, which is the most simple of the three phases.
- Explains that the bar clearance phase of the high jump involves a certain amount of kinetic energy and gravitational potential energy.

- Qualitative Anatomical Analysis: A Standing Broad Jumpexplanatory essay...ject’s/object’s weight multiplied by the velocity the subject/object is moving at, squared. In order for the broad jumper to increase the change in kinetic energy he/she needs to produce a faster velocity. This would mean he/she would have to produce a quick and efficient transition from flexion to extension at the beginning of the broad jump. Potential energy is defined as the amount of energy that is “stored” within a subject or object. The mathematical formula for potential energy is PE=mgh, where “m” mass, “g” is the acceleration of gravity (9.81 m/s), and “h” is height. The broad jumper has most amount of potential energy when he/she is at the apex of the flight phase. In order to increase the amount of change in potential energy the athlete must obtain the greatest height possible. This allows the athlete to fall longer, thus obtaining a further distance.

Duncan has once described Macbeth’s love “sharp as his spur”, and Macbeth has also described Lady Macbeth’s love “dearest partner of greatness”. Similar to every marriage and couples have, Macbeth and Lady Macbeth had their peaceful and amusing life as a husband and wife, too. However, Lady Macbeth was rather strange, mentally, and obsessive towards the position of the King. Lady Macbeth wanted the luxurious, and carefree life of being the King and Queen of the country, Scotland.

1872 wordsRead More - Athlete Acceleration and Its Effectcomparative essayAcceleration is an essential component in many different field sports including games such as rugby, soccer, American football and tennis (Spencer, Bishop, Dawson and Goodman, 2005). It is widely considered the most important attribute in team sports (Wilson, Lyttle, Ostrowski and Murphy, 1995), therefore the ability to enhance it would be valuable to many sporting events (Cronin and Hansen, 2006). An athlete’s ability to accelerate is dependent upon numerous factors, including technique/body position (kinematics) and the force production capability (kinetics) of the body (Cronin, Hansen, Kawamori and McNair, 2008). Important kinematic factors that affect acceleration performance include step frequency and step length (Hunter, Marshall, and McNair, 2004; Murphy, Lockie and Coutts, 2003), duration of the stance phase (Murphy Lockie and Coutts, 2003), position of foot strike through the athlete’s centre of mass (Chu and Korchemny, 1993), knee flexion angle before and after foot strike (Murphy, Lockie and Coutts, 2003), the magnitude of hip extension at toe-off (Vonstein, 1996), the angle of take-off of the athlete’s centre of mass at toe-off (Hay, 1985) and trunk lean progressively decreasing from 45⁰ to 5⁰ (Baechle, and Earle, 2008).

In this essay, the author
- Explains that this investigation aims to determine the ideal air pressure inside and ideal material of a ball in order for that ball to achieve its greatest bounce height.
- Explains how the air pressure inside a ball influences the bounce height/vertical motion of that ball.
- Explains how the material of a ball affects the bounce height/vertical motion of that ball.
- Explains that this investigation aims to determine the ideal air pressure inside and ideal material of a ball in order for that ball to achieve its greatest bounce height.
- Explains how the air pressure inside a ball influences the bounce height/vertical motion of that ball.
- Explains how the material of a ball affects the bounce height/vertical motion of that ball.
- Explains that air pressure can be defined as the impact air has against all the surfaces the molecules of air touch.
- Explains that c = centre of the ball, v = velocity (m/s), a = acceleration due to gravity (9.8 m2/s2), and g = gravity.
- Explains that during the first stage, where the ball is at rest, it possesses its maximum stored energy as a result of its vertical height above the ground.
- Explains that when the ball first makes contact with the surface of the ground, all the stored gravitational potential energy is transferred to kinetic energy.
- Explains that the velocity ball has reached 0m/s and its kinetic energy has been transferred into elastic potential energy, but the amount of energy actually transferred to produce a rebounding force is dependent on the air pressure inside the ball and the material it is made of.
- Explains that the ball's velocity increases in the opposite direction as it rebounded from the ground with acceleration still pointing up. the ball will not return to its original drop height and create a bounce height.
- Explains that the ball is now just touching the surface so it has returned to its original shape so all the elastic potential energy has been transferred back into kinetic energy and again.
- Explains that the ball has fully rebounded off the ground and has begun transferring all its kinetic energy back to gravitational potential energy again.
- Explains how the coefficient of restitution can be used to measure how efficiently and how much kinetic energy has been transferred to elastic potential energy when bouncing a ball
- Explains that the basketball has the greatest bounce height because the outer layer contains a rubber mix unlike the other balls, which will increase the flexibility of the ball.
- Explains the relationship between the air pressure in a ball and the bounce height of that ball where the drop height, temperature, and location are kept constant.
- Explains the effect of the material of a ball on the bounce height of that ball where the drop height, temperature, location, ball, and air pressure are kept constant.
- Explains that if the air pressure inside a ball is changed, it produces the greatest bounce height.
- Explains that the ball with the most elasticity in its material, which is the basketball, produces the greatest bounce height because it loses less energy to heat and sound since it can decelerate slower due to its flexible material.
- Explains that the more air there is inside an object, the greater the air pressure in that ball.
- Concludes that the heaviest ball will have the greatest gravitational potential energy transferrable if it has a sufficient elasticity for that energy to be transferred to elastic potential
- Explains that ek = gravitation potential energy (j), m = mass of the ball (kg), and v = velocity (m/s2).
- Explains how the ball deforms depends on its elasticity, which is the ability of an object to revert back to its original shape.
- Explains that the higher the coefficient of restitution, the greater elasticity that ball has, meaning it will have the greatest bounce height.
