The science of human motion is known as biomechanics. The study of biomechanics is crucial for discovering what causes injuries and, as a result, how to prevent them from happening again. Physiotherapists have received specialized training in detecting biomechanical flaws that might lead to injury.
Newton’s law
Law of inertia
Objects resist variations in their state of motion, according to Newton's First Law of Inertia. Unless acted upon by a force, an item in motion tends to stay in motion, and an object at rest tends to stay at rest.
Law of acceleration
Newton's Second Law specifies the amount of motion that a force causes. An object's acceleration (tendency to change speed or direction) is proportional to the amount of the force and inversely proportional to the mass of the item.
Law of reaction
According to the Third Law, there is an equal and opposite reaction force for every action (force). This means that forces between interacting bodies do not operate alone, but rather in equal and opposite pairs.
Type of Momentum
Linear Momentum
Linear momentum is a momentum that occurs in a straight line, for as when an athlete sprint down the 100m straight on the track in a straight line.
Angular Momentum
Angular momentum, also known as rotational momentum, is generated by the rotations of various body segments, such as the arms and legs. The forehand in an open stance generates a lot of angular momentum. The usage of angular momentum in ground strokes and serves has increased dramatically, which has had a substantial impact on the game of tennis. The inclusion of angular momentum into ground stroke and serve tactics is one of the key reasons for the game's current growth in power. At contact in tennis, the angular momentum created by the coordinated action of body segments is transferred to the racquet's linear momentum.
Human motion during exercise and sports is studied by sports biomechanics. Athletic performance is based on physics and mechanical laws. Individuals can benefit from biomechanics by studying their movements and receiving coaching for more efficient movement during exercise and sports.
