High Jump
High jump is a great sport. First, high jump has been a part of the modern Olympics since it started in 1892. Also, high jump contests were popular in 1892. Next, for high jump athletes will need high jump crossbars, pits and shelters, high jump standards, replacement spike, and equipment. If the crossbar falls off the holder during the jumper's turn, the jump is considered a miss! Lastly, jumpers must take off one foot. A jump is considered a failure if the jumper knocks off the bar. There are also Newton's laws in the sport of high jump.
There are multiple ways high jump shows Newton’s 1st Law of motion. In Newton's first law it says, an object at rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force. A balanced force is when an object at rest will stay still and nothing is acted on to it. An object that is unbalanced is something that is moving that causes motion. Rest is a balanced force that will stay still until a person applies force to it. In high jump, the athlete causes rest when they are still and when they are getting ready to jump. Motion is an unbalanced force that will move until it hits something or until it loses its energy. In high jump, the athletes cause motion when they jump over the bar and land on the mat.
There are several reasons why Newton's 2nd law is in the sport of high jump. First, acceleration is a change of speed when you use acceleration in motion. The acceleration of an object depends on the force applied to it (speed). When the athletes run to the bar it is speed, which is acceleration. Next, mass is the amount of matter in an object. Mass can move from place to place. In high jump the mass is both the athlete and the high jump bar. Last, a force is a pull or push in a specific direction. A force in high jump is the athlete jumping and pushing themselves over the bar. Finally, There were several reasons why Newton's 2nd law is in the sport of high jump.
There are several reasons why Newton’s 3rd Law impacts the sport of high jump. To start, Newton’s 3rd Law says that every action has an equal and opposite reaction in many different objects. Action is motion and reaction is action that happens in a response to an external force (an act). Additionally, action in this sport is when they run, jump, and when they push from the floor and from their feet and go forwards to jump over the bar. Action is motion and can sometimes be a force and sometimes forces come in pairs. To continue, the reaction in my sport is when the athlete pushes themselves over the bar. Reaction is an action that happens in response to an act. In conclusion, that's how Newton's Laws impact the sport of high jump in several different ways!
