The Science of Track By: Rajnarine Singh Class: 808 Introduction to Science of Track ) I picked track because you use a lot of energy when you run and you cant waste your energy all at once. Potential Energy Potential energy is when you are not using your energy yet but you can. For example in track before you start running you get into a pose to give you a good start at running. Kinetic Energy Kinetic energy is when your using your energy. For example you use your energy in track while you are running. Digestive System The digestive system is what put the food you eat to energy and this is good for track runners cause they need energy to run fast. Respiratory System The respiratory system cleans incoming air and this is good for track runners because they need clean air so they can get energy. Circulatory System The circulatory system consists of the heart, blood, and blood vessels. It needs energy to pump the blood throughout the body. Track runners need this because they need a good heart to run. Excretory System The excretory system releases water and salt from the body as well as releasing excess heat. Track runners need this so they wont over heat. Muscular System The muscular system is the thing that makes us move. Track runner’s need this because if they can’t move they can’t run! Electric Energy Electric energy is the flow of electrons around a circuit. Trach runners need this so they can moveœ Energy Transformation When you eat a lot you become fat that’s a energy transformation or when you work out. Track runners need this so they can get stronger. Conserving Energy Conserving energy helps track runners in two ways one is at the end of the race if the track runner saved his energy at the end he can blow it to the finish line and the other reason is that they can run faster when they save there Newton’s 1st Law of Motion Newton’s 1st Law says that an object in motion will want to stay in motion and object at rest will want to stay at rest unless acted upon an outside force. This rule for track runners are if they run fast it will be hard to stop so that’s why they don’t have races that you have to go back. Newton’s 2nd Law of Motion Newton’s 2nd Law says that the greater the force acting on an object, the greater the acceleration, or change in the object’s motion. So that means the faster you move your legs the faster you run. Newton’s 3rd Law of Motion Newton’s 3rd Law says that “For every action there is an equal and opposite reaction.” So when you run the opposite action is your getting tired. Machines Machines help track runners work out by you know the bike that wont move no matter how hard you pedal, that helps you work out your legs. Conclusion So track is related science in many ways but the important one is energy because with out energy track runners wont be able to run fast
