An inflated basketball needs alot of force.
​​The Physics of Dribbling a Basketball:
When you push a basketball against the ground why does it come back?
When a basketball falls to the ground or is dribbled (A hand pushing down on the ball)…the ball obviously bounces back. This occurs due to the elastic collision that occurs between the basketball and the ground. This happens because the air particles in the ground, because the ball is elastic material.

When the ball dents, the same amount of particles that appeared before the impacts are being passed into a teenier space and become even more packed and bounce of each other at greater velocity.-Because the particles are in this state, they keep continuing to bounce off of each other and the inside wall, causing the ball to inflate to its original condition. Therefore, it rebounds in the opposite direction. NEWTONS THIRD LAW! Which states: for every action (bouncing the ball with your hand) there is always an equal and opposite reaction (the ball bouncing back).

​​However, when the basketball is inflated, you have to use more force for the ball to come back to you. The ball even bounces in the first place due to GRAVITY!
When the basketball is dribbled, and in the process of dribbling, hits the ground. The other force of the ground causes the surface of the ball to dent.

Newtons First Law is also applied because when the ball is just sitting on the court, the ball is at rest. Then when you dribble the ball, an unbalanced force is acted upon it. The unbalanced force is your hand hitting against the ball. When you hit against the ball the ball moves making the ball become in a state of motion. The more acceleration you apply on the ball the faster you will dribble, making you handle the ball better--making you a better pointgaurd.

When you dribble a basketball Newtons Third law is applied on the baskteball. As you see on the picture in the top right, when you dribble the ball, an opposite reaction occurs and causes the ball to come back (your hand hitting the ball is the force and the ball coming back is the opposite reaction). A inflated ball wouldnt even hit off the court.

A Basketball in the NBA has alot of grip so that the friction increases between your hand and the basketball. You could say that the grip on the basketball acts like road salt, making the surface rougher so a car wont slip on the ice. Its the same thing, the people who designed the basketball made grip, so the ball doesnt slip out of your hands when you dribble. As you know the basketball has grip, meaning the friction increases everytime you dribble.



VIDEO:
Mr. Otter is a professional basketball trainer for the NBA.

Explanation of POWER DRIBBLING video:
Did you see how fast he was dribbling? He was applying Newtons third and first law. Every action has a reaction. And when you dribble the ball, its in a state of Motion. Another science concept applied to the basketball is
Momentum. Momentum is increased when you dribble faster and apply more acceleration to the force of you hitting the basketball. Momentum is mass x velocity, and all moving objects have momentum. So, when you dribble an object at rest, its in motion (Newtons first law) and the object has momentum. When you increase acceleration the momentum is greater. When you cross over the basektball, like he does in the beginning of the video, you apply a change in direction, and the momentum grows. The inertia must be weak when you go between your legs, behind your back and cross over, because nothing is stopping the change of motion. Also, the grip of the basketball had alot of static friction in this video because he never lost handle of the ball. The ball always came back to him as well. Did you see how pumped up the ball was? The ball had alot of air and he didn't need to apply alot of force. However, Mr Otter did because he wanted his acceleration to increase. Because of Newtons third law, it always bounced back. To be a great pointgaurd, BE EXPLOSIVE, and apply alot of force.
