Air Pressure
By. Anuj & Adrian
Problem: What is the effect of the air pressure in the back wheel of my BMX bike on how far I can catwalk my bike? (Note: A catwalk is a stunt that you do by lifting up the front wheel while pedaling.)
Hypothesis: The higher the air pressure in the tire the farther you will catwalk. The lower the air pressure in the tire the shorter distance you will catwalk.
Materials: The materials that you will need are:
-Gage that measure tire's pressure
-Tape measure
-BMX bike
-Air pump
-Tape
Procedure:
Step#1: Get these materials, gage, tape measure, BMX bike, and a air pump.
Step#2: Take the tape measure and stretch it out on the floor.
Step#3: Take the gage and measure the air pressure in the back wheel.
Step#4: Record air pressure on a piece of paper.
Step#5: Do a catwalk and where you stopped, record the distance of the length you covered.
Step#6: Repeat this procedure with different air pressures and keep recording data.
Observation: We saw that the higher the air pressure in the back tire the farther you did a catwalk. We also saw that the higher the air pressure in the back tire the less stable you are when doing a catwalk. When the air pressure was low the shorter distance you will cat walked but more stable. It was very hard to pedal when the air pressure was low in the tire.
Conclusion: We came to the conclusion that the higher the air pressure in the tire the farther you will catwalk. The lower the air pressure in the tire shorter distance you will catwalk. In other words our hypothesis was correct.
Application: Air pressure is very important because it keeps things balanced. It's used in many technologies such as bike tire, cars, trucks, and airplanes. Air pressure is important in airplane tires because if the air pressure was not right it might crash resulting killing many people on board. Air pressure plays a part in some fields of the science world and as well as life itself.
