Usain Bolt Experiment

Abstract:

This experiment was conducted to calculate the running movement and velocity of four people running in a straight line for 100 meters and compare them to the all-star Usain bolt. Usain bolt is the number one all-star ranking, the best and fastest runner ever. The things I could have improved on were that I didn’t really contribute that much to the experiment due to me being sick and non-present for the experiment itself. Things that I did well on were getting down all the results onto the Microsoft excel. The conclusions made from this experiment were that Usain blot is still faster than everyone else and the boys are still faster than the girls by a large amount.

Aim: The aim of this assessment is to investigate and compare the speed and velocity of StAC’s students against Olympic runner Usain Bolt.

Introduction: A force is a push or pull upon an object resulting from the object's interaction with another object.

Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction .The forces in the motion of a running person are propulsion (this is the force applied onto the muscles for a forward motion causing acceleration, wind (this is the force put onto the runner by the wind [can cause acceleration or deceleration] depending on the direction), drag (this is the force of air resistance which can cause deceleration and gravity (witch effects everything it is keeping us for flouting around and why things hit the ground. In this assessment we used all three of newton’s law3 for example every object in a state of motion remains in that state of motion unless an external force is put onto it. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma and for every action there is an equal and opposite

reaction.

Hypothesis: it was hypothesized that the runners that would speed up at the start then slow down at the middle then speed up at the end. I said that this will happen because when the runners start the acceleration will go up then it will go down because they will tired then they will see the end and speed up because. I predict that the guys will be faster then the girls because guys have longer and stronger legs.
