Basketballs bounce because of the pressurized air inside of them, gravity and Newton’s Laws of Motion. When you dribble a basketball, your hand and gravity both push the ball towards the ground (Law #1). As it drops, the ball accelerates and speeds up (Law #2).
What forces act on a basketball?
A basketball approaches a hoop
From the moment it leaves a player’s hand, the only forces acting on it are gravity (vertically downwards) and air resistance (opposing the direction of motion). Gravity causes the ball to accelerate downwards throughout its flight.
Why do basketballs have dots?
Adding these bumps was all about friction. … 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.
Why does a basketball stop bouncing?
If you drop the basketball, the force of gravity pulls it down, and as the ball falls, its potential energy is converted to kinetic energy. … This is because the basketball had an inelastic collision with the ground. After a few bounces, it stops bouncing completely.
How high do you shoot a basketball?
Most shots enter the rim between 35 and 55 degrees, but as mentioned, the perfect shot – guaranteed to go in every time – is shot straight and 11 inches deep in the basket at a 45-degree angle.
What is a balanced force in basketball?
One balanced force in basketball is standing and shooting a freethrow,because you aren’t moving and no outside force is acting on you. But, an unbalanced force is running down the court and jump-stopping, because your momentum is trying to keep moving forward, but you are trying to stop. Another force is Net force.
How is gravity used in basketball?
When you shoot a basketball, you exert an upward and forward force in the direction of the net. Gravity exerts a force downward on the ball, causing it to travel in an arc as it approaches the rim. … This spin creates a difference in pressure above and below the ball, and generates an upward force.
Is a basketball being held a balanced force?
Newton’s First Law: When the boy is simply holding the ball in his hands there is a balanced force which prevents the ball from moving. According to Newton’s first law of motion, the only reason why the ball stops accelerating downward is because of the external force of the ground acting on it in the other direction.
What happens when two objects collide?
In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).
