What happens to the bounce of a basketball when you leave it outside in the winter?
As the temperature decreases, gas molecules contract and move around more slowly with less energy. Thus, lower pressure leads to a lower bounce of the ball. That’s why a fully-inflated ball might appear deflated if the temperature drops dramatically.
Why does a basketball bounce differently inside a gym than it does outside on a cold wintry day?
The pressure inside a basketball decreases as the temperature decreases. The increased pressure causes the ball to expand and bounce into the air. On a cold day, the pressure inside the basketball decreases (Gay-Lussac’s Law).
How does the air pressure of a soccer ball affect the distance it can travel when kicked?
The pressure in the atmosphere will also affect how far the ball when kicked. The lower the pressure then the less friction there is for the ball to travel. -Air pressure determines the ball’s level of stiffness. Having less deformation of the soccer ball means it will have good height and distance when kicked.
What factors influence air pressure?
1)The 3 main factors that affect barometric (air) pressure are:
- Temperature.
- Altitude or Elevation.
- Moisture ow water vapour.
How does air pressure affect the bounce of a basketball?
As the air becomes more squished, it pushes more on the inside of the ball. With more air in the ball, the air starts at higher pressure and pushes back that much harder when the ball is bounced. So that short answer is that more inflated basketballs bounce better because they have more air pressure inside them.
What is the air pressure of a basketball?
between 7.5 and 8.5 psi
An NBA regulation ball is inflated to between 7.5 and 8.5 psi. By regulating a basketball’s air pressure, the NBA can ensure fair playing conditions.
According to the ideal gas law, the pressure of contained volumes of gas change with temperature. This basic physical law has serious real-world implications for the bounce of a basketball. When the air temperature around a basketball increases, the pressure inside the ball increases. When the air temperature decreases, so does ball pressure.
How does air pressure affect a tennis ball?
Thus, when the ball is dropped with an increased pressure, the molecules cause the ball to apply a bigger resistive force under deformation, allowing the ball to store more EPE and bounce higher (Hutchison. P, 2015).
What happens to the ball when it bounces on the ground?
But when the ball bounces on the ground, it deforms and increases the air pressure around the deformed area and rapidly throughout the ball’s interior. The uniform pressure during the bounce increases because the contact of the bottom of the ball with the ground reduces the ball’s volume.
What makes a basketball have a good bounce?
The key to ensuring a good bounce is proper maintenance and consistent air pressure. The air pressure inside a basketball has the biggest affect on bounce, but you should consider outside air pressure and temperature when pumping up your ball.
