Question

Explain how Newton's second law of motion is used in sports?

Answer 1

 Newton’s second law states that acceleration is proportional to net force, and inversely proportional to mass. This means that the greater force applied, the greater the acceleration, and the greater the mass, the lower the acceleration. Therefore if we were to use a different ball with a greater mass, it would accelerate slightly slower, This law comes into play in two different places. The first time is with gravity. The force that gravity excerpts on an object will depend on the mass of the object, since the acceleration is always the same. Since we know the mass of the ball and the acceleration due to gravity, we can calculate the force of gravity on the ball by multiplying the these two things together:  

Example....

     Therefore the force of gravity on the ball is 0.54N [DWN]

     The second time this law comes into play is during contact between the ball and the racquet. When in contact with the ball, the racquet is applying a force to it, causing it to accelerate. In order to find the amount of applied force, we must use the same equation as above, but use the acceleration of the ball instead: 



     Therefore the force applied to the ball by the racquet is 2.5x10^2 N.

     Since this force is applied at an angle, the vertical component has overcome the force of gravity, however the force of gravity is so small that it would not change the final result when using significant digits, and therefore we can just use this calculation as it is much simpler.

     We know this law occurred because out of these two examples, the one with the higher force produced a greater acceleration. Had this law been false, this would not have happened, but since it did, we can tell that acceleration is, in fact, proportional to force.

Answer 2

Sport movements are based on the concepts of Newton's laws of motion. Training regimens that deviate from these laws would not make mechanical sense. These laws and concepts serve as the foundation for advice on effective sporting performances.

Knowing that there are two fundamental forms of motion is helpful. When applying mechanical concepts to sports talents, the following are relevant in combination:

1. When an object or person moves linearly, as when sledding on a level surface, they move in a straight path.

2. When an object or person rotates about a central point, axis, or fulcrum without moving from one location to another, this is known as angular motion. Divers and gymnasts frequently rotate, twist, or spin during their manoeuvres.
