How Do Under-Inflated Tires Affect the Difficulty of Riding a Bike?
Repeat steps 6-10 for each of the remaining tire pressures (50%, 75%, and 100%). Use your bike pump and pressure gauge to increase the pressure in both tires before each new set of trials. Be sure to record all your results in your data table. For each tire pressure, calculate an average force and enter this value in your data table. For ...

Why Soda Fizzes
If you decrease its pressure, its volume increases. You can observe a real-life application of Boyle's Law when you fill your bike tires with air. When you pump air into a tire, the gas molecules inside the tire get compressed and packed closer together. This increases the pressure of the gas, and it starts to push against the walls of the tire.
Air Pressure Experiments for Middle School
For this air pressure experiment, students should fill a 2-liter plastic bottle with water halfway. Place a large straw in the water so that it extends out the top of the bottle. Cover the opening of the bottle around the straw with clay so that no air can go in or out except through the straw. When students blow in the straw, it will raise the ...
Tire Pressure (Pressure, Force)
Tire Pressure (Pressure, Force) | Physics | Interactive Simulation | CK-12 Exploration Series. ... 0 %. Uncover the relationship between pressure, force, and contact area in the context of a truck tire using our interactive simulation.
Tired Weight
To find the amount of weight the tire supports, multiply the surface area by the air pressure reading (psi) for that tire. When you multiply square inches by pounds per square inch, the square inches cancel and you're left with pounds. For example: 28 square inches x 30 pounds / square inch = 840 pounds. Repeat the steps above for each of the ...
Rolling Friction
That is why it is important to maintain proper tire tread depth and pressure in order to balance the amount of traction and speed. The surface of a tire affects rolling friction, the frictional force between a round object such as a tire or a ball over a surface. ... In this fun science experiment, make a balloon car and test it on different ...
Slip Sliding Away: Experimenting with Friction
Make sure that the pieces of wood have surfaces that are similar in roughness and are about the same length and width. Take one piece of wood and soak it in water—this can be done by weighing the wood down in a bathtub filled with a few inches of water for at least 30 minutes. Place the soaked piece of wood in the freezer overnight.
PDF Auto Tire Pressure
To do this, first subtract the actual tire pressure from the recommended pressure provided by the manufacturer. This is the diference in psi from normal pressure. Then multiple the diference in pressure by 0.4. The product is the impact in percent eficiency. For example, if the manufacturer of an American mid-range light SUV recommends 35 psi ...
Charles's Law and Tire Pressure...
In today's language we know that if the amount of air in a tire remains constant, the pressure will be directly proportional to the temperature. So, if a tire has 35 PSI, (Pounds per Square Inch) at 68 F (20 C), and the temperature drops to 32 F, (0 C), the tire pressure will go down. As a result, depending on the tolerance of the sensor, the ...

PDF Top Ten Air Pressure Experiments to Mystify Your Kids
Fountain Bottle Seal a 2-liter soda water bottle (half-full of water) with a lump of clay wrapped around a long straw, sealing the straw to the mouth of the bottle. Blow hard into the straw. As you blow air into the bottle, the air pressure increases. This higher pressure pushes on the water, which gets forced up and out the straw.
10 Easy Air Pressure Science Experiments for Kids
Why it works: Blowing air between the balloons lowers the air pressure and makes the pressure surrounding them higher, pushing them together. Allison Sutcliffe. 4. Levitate Water. You won't need to incant Wingardium Leviosa with perfect pronunciation to suspend water during this exciting experiment.
Balloon in a Bottle : Air Pressure Experiment
Preparation. Just keep a hole at the bottom of the 2 litre bottle using nails or any other sharp ended object available around. Ensure the hole is made close to the bottom of the bottle. Get the Balloons ready for the experiment. Make sure there are no holes. Leave the 1 litre bottle without any holes.
Science Projects for Kids: Air Pressure
What happened? The force of air pressure against the card is stronger than the force of gravity on the water. The air pressure holds the card in place. In fact, the force of air pressure is so great that you can even use it to crush a can. Find out how with the next science project in science projects for kids: air pressure.
Air Pressure Experiment for Kids
Cold water. Hot water. Refrigerator. EXPERIMENT STEPS. Step 1: Peel the labels off each water bottle so kids can see what is happening inside the bottles during the experiment. Step 2: Fill one water bottle with cool water. Step 3: Fill the second water bottle with hot water. Use hot pads, if needed, to avoid burning hands.
You can see this in the diagram below (click to enlarge). Depending on the vacuum cleaner, the pressure inside the bag can be reduced from 5-20%. When we tried this experiment at the Exploratorium, we averaged a little over 1 psi (about .1 atm or .1 bar) reduction in air pressure in the bag using a 12 amp vacuum—close to a 10% reduction in ...
Air Pressure Bottle Experiment
Fill the bottle about 3/4 full with water. Add food coloring if desired. Inflate a balloon and twist the neck of the balloon to keep the air in the balloon. Slide the mouth of the balloon over the top opening of the bottle. Untwist the balloon to allow the air to push into the bottle. Watch as the water gushes out of the bottle and through the ...
