Newton's 3 Laws Of Motion

In sport, an understanding of biomechanical principles allows athletes and coaches to breakdown movement and learn the correct way to execute a skill (Singh Yadav, 2016, P 669-670).

The fastest growing sport in America is lacrosse, and in order to play lacrosse, it is important to first understand the physics of the game. Lacrosse players around the world use physics while playing without even thinking about it. With no knowledge of physics, it would be pretty difficult to master the fastest game on two feet. One of the worlds greatest scientist, Isaac Newton, established three laws dealing with physics, and using these laws will make it possible for a lacrosse player to understand what he or she needs to do in order to throw a ball. Newtons first law deals with inertia, his second law deals with the relationship between mass, acceleration and force, and his third law deals with opposite reactions. When talking about lacrosse, it is essential to cover Newton’s first law, his second law, and his third law in order to understand the physics behind throwing a lacrosse ball. .

Suppose a Hard mini ball is placed in an automatic air power sealed containerYou will notice that no matter how much you will leave the ball bunching the ball will never stop bouncing. That happens because the ball develops both potential and kinetic energy,the sum of those two give us the mechanical energy which remains constant.

and the hand continues through its motion. Angles were placed on each still shot at the

Newton’s first law of motion states that an object in motion will remain in motion, while an object at rest will remain at rest unless acted upon by another force. This seems to be true with humans as well because it is more likely that a person will remain active in their later years if they remain to be active through the critical time of their late teens and twenties. Because a major portion of this age category is in college, it is crucial for universities and community colleges to provide physical education to help students achieve and maintain a standard level of physical and mental fitness outside and inside the classroom.

There are three laws of motion. Nancy Hall states that Isaac Newton worked in many areas of mathematics and physics. In 1666, when he was 23 years old, he developed the theories of gravitation (2015). Otherwise known as Newton’s first, second, and third Laws of Motion. In agreement with HyperPhysics, “Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force” (HyperPhysics). Newton’s first law can also be recognized as the Law of Inertia. Essentially, what Newton's First Law is stating that objects behave predictably. For instance, a chair is not going to move unless a force is acted upon

“Playing basketball can be hard work. Players not only have to run around the court, but just dribbling the basketball takes some serious effort, too.” (“Surface Science: Where Does a Basketball Bounce Best?”). Energy reserved inside the ball, transfers into Different types of energy (ex. Heat, sound) when the ball hits the ground. But, which type of court restores the most energy back into the ball?

     Newton?s third law says that every action has an equal and opposite re-action. These are two separate forces, which act upon two separate objects, and so they do not cancel each other out. If you punch someone?s face, not only does your hand apply force to the victim?s face, but also the victim?s face applies a force on your hand. Therefore, your hand hurts and so does the victim?s face but since the face is softer than the hand, it will hurt more. If you push a van with roller blades on with 100 Newtons, you will be pushing the van at 100 N and the van will be pushing you at 100 N. In a second, bob will have moved 2 m and the

Newton’s First Law of Motion, inertia, says that an object at rest will remain at rest and an object in motion will remain in motion will remain in motion unless acted upon by an unbalanced force. The ball will not move forward until the server hits it into play and it will not stop until it hits the net or the ground. The second part of the law is momentum where an object in motion will stay in the motion of a straight line with a constant speed unless acted upon by an unbalanced force. The ball will continue to move in a straight line or an arc until a player blocks the ball from traveling any farther. Newton’s Second Law, force, states that force equals mass times acceleration (F=ma). For volleyball, the more force applied to the ball, the further it will go. This is very important in volleyball because the players need to have the perfect amount of force on the ball to get it over the net but keeping it in bounds. Newton’s Third Law of Motion states that for every action there is an equal and opposite reaction. The player hits the ball with a certain amount of force, the ball hits the player’s hand with the same amount of force. In volleyball, the player’s upward motion pushes the ball up, where the opposite reaction is the downward motion of the player’s arm after hitting the ball

The discovery of these laws, laid down a basic foundation for the physics of motion. Newton's three laws of gravity changed the way in which the world was perceived, because of their accuracy in describing many unexplained phenomenons.3 They explained what happens as a result of different variables, but most importantly, they explained why and how these actions happen. Like many of Isaac Newtons ideas and theories, the three laws of motion had a profound impact on the scientific community. The three laws of motions provided an explanation for almost everything in macro physics. Macro Physics is the branch of physics that deals with physical objects large enough to be observed and treated directly.4 This allowed for many new advancements in physics because the foundation had been build for others to develop upon. Isaac Newton published these findings in his revolutionary book “The Principa”. The Principa was revolutionary book because it organized the bulk of his life’s work, More importantly the

Another basic element of basketball is that of passing the ball to another teammate. The physics involved in this process are velocity, momentum, and impulse. The ball has a mass and when it is thrown a velocity of the ball in created. From these two parts momentum is derived, P=mv (Kirkpatrick Wheeler 106). While playing basketball it may be to your advantage to increase or decrease the momentum of the ball when passing to a teammate depending upon the situation.

The first description of a shot was described earlier as simply a shot but more specifically can be referenced to a jump shot. The second way to look at shooting the basketball using physics is referred to as a layup. The difference between the two is that a jump shot has little or no horizontal movement toward the basket. Instead the jump shot relies strictly on vertical movement. Specifically the shooter will be stopped and jump using two feet straight up and down vertically and push the basketball off the finger tips to obtain the force and angle to get the ball to the basket. The layup on the other hand is done by the shooter jumping off of one foot while running. The shooter jumps vertically and uses the momentum from running to propel horizontally toward the basket. The shooter is generally closer to the basket while shooting a layup versus a jump shot. The same physics that were applied to the jump shot are applied to the layup as well. There is still an angle and force that the ball would need to travel toward the basket but since the shooter is moving horizontally toward the basket velocity will play more of factor. Since the balls velocity is the sum of the shooters speed and the balls speed the ball does not need as much force to get to the basket but it is more or less just let go of or dropped off into the basket. This also explains the slam dunk. Instead of dropping the ball into

Newton’s second law states that the force of an object is dependent on its mass and acceleration (Van Daal). The basic version of this is that if the resulting force of an object doubles, then the acceleration also doubles, they are directly proportional. It also means that if the mass of an object doubles then the force will also double. Another way to prove this law of motion is by dropping a marble and a wadded up piece of paper at the same time (Home Training Tools Staff). Even though they would have the same acceleration the marbles force will be stronger because of the increased mass. In Newton’s second law of motion it states F=MA or force equals mass times acceleration so because the mass increases the force would. Another way to show this law is true is that if you want to move an object with more mass you will need more force (Hall). This laws can show many things if an object has a high acceleration it will need more mass to stop the object would cause a lot of force at impact. The normal way for this equation though is the more mass the stronger the force or the higher the acceleration the stronger the force. Newton’s laws of motion are very important and they will always be very important in the modern

“I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.” – Sir Isaac Newton (Brewster, Memoirs of Newton, 1855)
