The Science of Cheerleading By: Francy Rios Class: 807 By: Francy Rios Class: 807

Introduction to Science of Cheerleading  I picked this sport for my science sports project because I like cheerleading, I’ve tried it before and even made the team. Cheerleading requires a lot of exercise and stunts.

Potential Energy  Potential energy is stored energy. An example of potential energy in cheerleading is when the cheerleader is getting ready to run to do a front hand spring or back hand spring.

Kinetic Energy  Kinetic energy is energy in motion. An example of Kinetic energy in cheerleading are bouncing, Jumping, Running.

Digestive System  The digestive system digests food to give our body energy. When cheerleaders eat it prevents them from getting weak.

Respiratory System  Respiratory system is what helps us breath, It helps us get oxygen into our body.

Circulatory System  Circulatory System is what helps all the blood in our body move and it helps our cells get oxygen.

Excretory System  Excretory System is what gets the sweat and the heat out of our body.

Muscular System  The Muscular System gives us strength to move our body. Cheerleaders need the Muscular system to Run, Flip, and Jump.

Electric Energy  Electric Energy is the charges that makes electricity flow. With electric energy we are able to see cheerleading contest on television and on the internet.

Energy Transformation  Energy Transformation is a energy that turns into another energy. One example is when food turns into kinetic energy and sweat becomes heat anergy.

Conserving Energy Conserving Energy can help athletes when the cheerleader takes a long nap before the big event, Also when they sit down to relax.

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. For example a cheerleader would would fall if she’s not balanced.

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. For example the stronger the jumper kicks of the ground the higher she/he will go.

Newton’s 3rd Law of Motion  Newton’s 3rd Law says that For every action there is an equal and opposite reaction. For example when the force of the cheerleaders go down they would have more strength to jump up.

Conclusion  Cheerleading is related to science because when cheerleaders our bodies get more strength, and our body needs the energy to move, Jump an dance. Electric energy helps us watch all the competition done with cheerleading.
