Trampoline
Every four years the best athletes come to compete to be the best trampoline jumper in the world. First, the origin of the trampoline. Trampoline was started in 1930 by a man named George Nissen who created the trampoline after attending a circus. Trampoline became an olympic sport in the year 2000. Next, the equipment, there’s a frame, mats and springs. Finally, the rules, you land on both feet so you don’t get hurt. You win by doing the best and most difficult tricks. Trampoline is very fun to jump on and also shows many concepts of physics.
Trampoline has many different forces. Unbalanced forces are seen when jumpers are jumping or when the springs are moving from the impact of the jumper. In these instances, forces of the objects are pushing against each other equally causing motion of the two objects. This causes the person to be able to jump. Balanced forces are not moving. Examples of balanced forces are the trampoline. Newton's first law of motion says an object in motion stays in motion unless a force stops it, and an object at rest stays at rest unless a force moves it. The sport of trampoline has Newton's First law because the jumper is at rest until the force of their muscles start to move them causing the motion of them jumping. The jumper also causes the springs to be in motion as they go up and down. Clearly, Newton’s first law of motion can be seen in olympic trampoline.
The greater the mass of an object the greater the force to move it. This is Newton's second law. A force is a push or pull. There are two kinds of forces, unbalanced and balanced forces. In trampoline unbalanced forces are the muscles in athletes' legs that make them jump higher and higher. Mass is the amount of particles something has. Examples of mass in trampoline are the athletes and the trampoline. Acceleration is change in velocity and velocity is the change in speed or direction. The acceleration of the jumper impacts the mass by jumping because the muscle in an athlets leg makes them jump higher and higher because they are moving their arms. The athletes on the trampoline can predict the acceleration of their body by moving their muscles in their arms. For example in a flip, athletes move their head and their body follows their head. To jump higher, athletes must move their arms to go higher and stop moving thier arms to jump lower. Overall, Newton’s second law can be seen throughout trampoline.
Newton’s third law says for every action there’s an equal and opposite reaction. As jumpers move their arms as an action, the reaction is that they go higher. As jumpers push down with their legs on the tramp as an action, the reaction is them going up in the air. Truly, the sport of trampoline has movement and is popular.Newton’s law can be seen throughout every movement of this sport.
