Recommended: Newton’s laws of motion and discuss the implications

Forces play two fundamental roles: to cause an object to move or to change shape (Lawler, 2018). Although there are a variety of forces to study- from inertial forces to gravitational ones- they all utilize at least one of those functions. Impact forces are no exception. Impact forces are those that involve a collision between two objects (Lawler, 2018). Impulse is a concept in physics that is governed by these ever-present forces. Impulse is the product of force and time that equals to the amount of change that the product of mass and velocity (momentum) undergo (Lawler, 2018). Human movement incorporates force in two ways: by maintaining static equilibrium- that is resisting the force of weight- and by generating acceleration, which is essentially a change in momentum (Schilling et al., 2008).

It is important to point out that although the two-footed jump exerted a greater maximum force as compared to a one-foot jump, the average force of the former is markedly lower. Keep in mind that force is a product of mass and acceleration. Since the same individual is performing different trials, the mass remains the same. The differences in the trials, therefore, reflect changes in acceleration. The average amount of force produced in a two-foot jump was 777.76 N, whereas a one-foot jump actually produced an average force of 889.38 N (Table 1 &2). Also, the two-footed jump had an elapsed time of 0.91 seconds, whereas a one-foot jump had a time range of 0.63 seconds. Be reminded that impulse is the product of both time and force, so the conclusion that a two-foot jump generated greater impulse seems plausible only if maximum force is taken into consideration. It is difficult to conclude whether our hypothesis is rejected by the average force values or supported by the maximum force values at least when looking at impulse as a product of force and

    According to Neumann, a force can be considered a push or pull that can produce, arrest or modify movement and can be measured as F=ma (Neumann, 2010). Force can also be considered the load. In regards to muscle contraction force relative to the joint, the force can be the internal force produced by the muscle itself, the force of gravity or the force of the particular load/weight. Torque is a cross product between force and the distance of the force from the fulcrum and is the ability of a force to cause rotation on a lever. Torque is a measure of how much a force acting on an

  • Essay On Calf Circumference

    1521 Words  | 4 Pages

    This experiment was completed in order to compare calf circumference as well as gender, weight, and jump height. If a person has larger calves, then they will likely be capable of reaching a higher vertical height. It can also be shown that if the person is a male, then they will be able to jump higher. A larger calf circumference is more likely to reflect a high vertical jump due to the fact that the fat content of the calves in the experiment was accounted for, therefore a large calf measurement in this experiment means a muscular calf. It is common knowledge that more muscle will result in stronger legs leading to a higher vertical. While it is believed that males are bigger, faster, and stronger, this leads us to believe that they can also jump higher. Males tend to have stronger muscles at nearly all points in life(Burr, 1997). That being said, the aforementioned hypotheses can be expected to be true because males are likely to have larger, and therefore stronger, calves. It can also be expected that males will display a higher vertical jump(Caruso, 2012).

  • Biomechanics of the Golf Swing

    1375 Words  | 3 Pages

    For years it was thought that the golf swing was a solid piece of movement without any differentiating variables. Vast expansion in technology over the last 20 years has produced more information on the biomechanics of the golf swing. “ Golf Biomechanics applies the principles and technique of golf mechanics to the structure and function of the golfer in an effort to improve the golf technique and performance” (Hume P., Keogh J., and Reid D. 2005) Biomechanics, “The scientific discipline that applies mechanical principles and to understanding movement.” (Hume P., Keogh J., and Reid D. 2005) allows scientists to observe a golfer’s swing to near milliseconds to the point of impact. This is much more precise to previous measurements used such as video recordings, outlines, etc. Understanding how the swing works by breaking down the movements within the swing through visual aids emphasize the opportunity for a better swing and in turn, better golf. Studies of biomechanics within the golf swing have shown the sequential separation from torso to pelvis, disproving the original theory of a solid swing with continuous motion known as the X-factor. Before understanding how the biomechanics of the golf swing works with the X-factor, the basics of the swing must be established.

  • 60 Jumping Jacks Lab Report

    On average, as the number of jumping jacks executed by a 15 year old female increases at increments of 30 the bpm of the participants immediately after should increase by 18 bpm. The hypothesis is also supported through knowledge of how one’s body reacts to exercise. During vigorous physical activity one’s muscles require a lot of energy. Although some of this energy can be produced by anaerobic metabolism the majority of the energy needed must be aerobic meaning it needs oxygen. Because the bloodstream is responsible for transporting nutrients, wastes, and gases like the aforementioned oxygen to one’s muscles, the heart must pump a large amount of oxygenated blood to support the muscles during exercise. To fulfill this high demand, the heart must beat faster to increase the amount of oxygen transported and to decrease the amount of waste like lactic acid. As the intensity of the exercise increases, or in the case the number of jumping jacks executed increases, the heart must beat even faster because the muscles would be requiring more oxygen since they would have to contract

  • Qualitative Anatomical Analysis: A Standing Broad Jump

    ...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.

  • Body Acceleration from Muscle Force of Countermovement Jumps in Comparison to Squat Jumps

    1467 Words  | 3 Pages

    Throughout literature countermovement jumps (CMJ) are seen to be higher in contrast to squat jumps (SJ) (Bobbert et al. 1996; Kubo et al. 1999; Bobbert et al. 2005). However present literature regarding the key potential mechanisms behind why greater muscle forces are seen accelerating the body upwards in CMJ in comparison to SJ is somewhat unclear. A CMJ can be defined as a positioning starting upright, beginning the descending motion in advance of the upward motion in contrast to a SJ where the start position is squatted with no preparatory countermovement (Akl 2013). The higher jump heights seen in CMJ in comparison to SJ are apparent even if at the start of propulsion phase the body configuration is identical (Bobbert et al. 1996). In past literature three main mechanisms have looked to provide an explanation for the greater muscle forces seen in CMJ than the SJ. The first plausible theory is that the muscle stretch in CMJ increases the production of force capability of the contractile machinery (Edman et al. 1978; Ettema et al. 1992; Herzog et al. 2003). Secondly the assumption that the muscle fibres are on the descending limb of their force–length relationship at the start of propulsion in the CMJ and SJ, however in CMJ the stretching of a chain of elastic components, they are not as far past optimum length therefore allowing a greater force over the initial phase of their shortening range, with the stretching of sequences of elastic components, this then causes the storage of elastic energy that is then reutilized in the propulsion phase (Ettema et al. 1992). The final explan...

  • Sir Isaac Newton's Second Law Of Motion

    1080 Words  | 3 Pages

    Newton’s second law explains how the velocity of an object changes when it is subjected to an outside force. In the second law of motion, force is defined to be equal the change in momentum which is mass times velocity per change in time. Since Sir Isaac Newton was also advanced in mathematics, he created a formula to formulate his second law of motion. The formula that he created for his second law of motion is F = m X a. In the formula the F represents force. The M in the formula represents the mass of the object. Lastly, the A represent the acceleration. The entire formula is used to find the product of an object 's mass and its acceleration. Newton’s second law of motion enhanced individuals today to calculate how much force one object

  • Biomechanics Of Running Essay

    1894 Words  | 4 Pages

    What is Biomechanics? It is the study of forces and their effects on the living system (McGinnis, 2013). In this essay, I will be looking at the biomechanics of running. Running, as well as any other sport requires skills for which advancement is due to consistent deliberate practice and effective development. However, runners should establish a training system that actively builds their original running pattern instead of basing it on what works well for others. Understanding the biomechanics of running gives a better knowledge of their running techniques and points out areas of concerns that require improvement. Despite the fact that running is dependent on the interaction of the whole body, breaking down the running pace into single components allows us to further understand how minor changes can increase improve performance and decrease injury risk.

Until she takes a step, the gymnast is at rest. When she is ready to tumble the gymnast applies the force. A gymnast takes a running start when approaching a tumbling run, and as she is moving across the floor she is increasing her momentum. This is a demonstration of Newton's second law.

    Interestingly enough, one can actually change their "terminal" velocity. For instance, if Joe were to jump out of the plane and position in the prone, spread eagle position, his surface area would be at his maximum. Thus the terminal velocity he would reach would be lower than the terminal velocity he would reach if he dove from the plane head first. When Joe transitions from spread eagle to the head first position, his surface area decreases, thus allowing for an increase in speed.
