Kinetic and Potential Energy. As you hold a basketball, it has built up Potential Energy. Potential energy, as we learned in basic Physics, increases as the ball is at a greater height. As you dribble, adding a force onto the ball, you convert Potential energy into Kinetic energy. This force you applied causes the ball to collide with the basketball court.
The air pressure increases as you fill it with air, but if you fill it too much there is too much air pressure which causes the ball to bounce uncontrollably. Dribbling the Basketball. When a player dribbles a ball, the ball exerts a force on the ground when it hits. The ground exerts an equal and opposite force on the ball which pushes it upward into the air.
The Physics when you Dribble: There are a lot of physics happening when you dribble the basketball. Dribbling the basketball can be explained through the laws of physics. In order for the basketball to come back up to your hand, the ball must have high air pressure. High air pressure prevents the ball from deforming on impact.
When you apply a force to the ball and begin dribbling it transfers the potential energy of the ball into kinetic energy. As the ball collides with the floor, the floor the pushes the ball back up to your hand. This is because of Newtons 3rd law: with every reaction there is an opposite and equal reaction. The faster and harder you push the ball the more kinetic energy it gets and the harder it bounces of the ground.
When a basketball is dribbled it hits the floor and the force of the floor hitting back on the basketball causes the basketball to indent. When this happens the volume of the ball is compressed causing all of the air particles in the ball to become more tightly packed, which causes the air particles to collide at much greater speeds.
If you want to find your speed when dribbling, calculate it by using the formula Speed = distance/time. Pretend that it takes me 9.5 seconds to dribble a ball 10 meters. I would plug this into the equation to find my average speed: 10 meters/9.5 seconds = 1.05 meters per second. Now, try to calculate your average speed when dribbling!
If you are 2 feet away from the goal, this will take about 10 miles per hour (mph) of speed for the ball to reach the correct distance and height of the basketball goal. For a 3-point shot, it will take roughly 18 mph of sped to reach the correct distance and height of the goal at 10 feet in height.
So the bumps on the basketball basically increase the surface area of the ball and the amount of friction acting on it. This makes the pebbled ball ideal for a player to grip, pass quickly, and dribble without fear that the ball will slip away in a random direction.
