Physics comes into play in basketball whenever a player jumps in the air to shoot or rebound. What enthusiasts call “hang time” — when a player appears frozen at the peak of his leap — is the result of projectile motion.

What kind of physics is basketball?
Parabolic motion (or projectile motion) Basketball is probably one of the sports in which the parabolic motion is most noticeable and is more frequent during the phases of a game. The player must try to throw a ball into a basket that is placed at a much higher level than his or her own.
How do you solve projectile motion in basketball?
Why do you have to throw a basketball at an angle above the horizontal to shoot it into the ring?
These angles produce the slowest moving ball as it approaches the rim, which gives you a shooter’s touch.
How does gravity affect basketball?
Gravity exerts a force downward on the ball, causing it to travel in an arc as it approaches the rim. If you snap your wrist at the moment you release the ball, the ball will spin from bottom to top as it moves through the air.
Why do some basketballs feel heavier?
Once you pump extra air into the ball, packing the air more tightly than normal and stiffening the ball’s surface, that additional air will appear on the scale’s weight measurement. A properly inflated basketball has about 0.01 pounds of extra air in it, so it’ll weigh an extra 0.01 pounds on a scale.
What type of energy is used in basketball?
When a basketball bounces, it has two different types of energy: kinetic and potential. Kinetic is the energy an object has due to its motion. Potential energy is that which is stored in an object—its potential for motion—such as due to its height above the ground.
How is speed related to basketball?
Speed is how fast or slow an object in moving. Speed can be the determining factor of winning or losing. If a team isn’t hustling up and down the court, they’ll most likely lose.
How is momentum used in basketball?
Momentum is applied to basketball when a player dribbles. When a player dribbling a basketball than they are causing the momentum to go downward. when the basketball hits the ground the opposite reaction occurs and the basketball goes upward.
Why is basketball an example of projectile motion?
When a basketball player jumps in the air to make a shot he can appear to be suspended in mid-air during the high point of the jump. This is a consequence of projectile motion. When an object is thrown in the air it will spend a large percentage of time in the top part of the throw.
What is the best angle to 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.
Why do thrown basketballs travel in arcs?
The arch caused by the basketball is a result of the gravitational pull upon the basketball, and if a basketball was thrown without a gravitational pull acting upon it, the basketball would travel continuously without arching (this also relates to Newtons 1st law).
Why 45 degrees is the best angle of trajectory?
A launch at 45 degrees would allow the ball to remain in the air for a longer time, but it would then be launched at a lower horizontal speed at the start and it would slow down more because of the longer flight time. An additional aerodynamic force arises if the ball is spinning.
Why do you flick your wrist when shooting a basketball?
Shooting with your fingertips gives you greater control over the ball and ensures the ball rotates with backspin during your “follow-through”. There should be a pocket of air between the ball and your palm. When you flick your wrist the last part of your hand to touch the ball should be your pointer/middle fingers.
What angle does Steph Curry shot at?
Steph Curry’s setpoint is just above his right eye. At his setpoint, his thumb is in line with his eyebrow and his palm is facing to the side. You will also notice that his arm makes a 90 degree angle at his armpit. The angle between his arm and his forearm is much less than 90 degrees.
How is Newton’s 3rd law used in basketball?
For example, when you bounce a basketball on the ground, the force of the basketball pushing down to the ground is equal and opposite to the force of the basketball pushing back up when it bounces.
How does basketball use force and motion?
For example, when a basketball is dribbled, it will hit the ground with a force. This force of the ball on the ground is paired with the force of the ground on the ball. This second force acts in the opposite direction, so the ball is propelled upwards. This relationship is important for many aspects of motion.
How does inertia affect basketball?
As Don Kelbick explains, inertia is when a body in motion stays in motion unless acted upon by an outside force. This is better than moving to the side because it shortens the distance of your shot. And when you are moving straight to the basket, it makes it easier to shoot in a straight line.
Which is heavier the inflated or deflated ball Why?
An inflated balloon is heavier than a deflated one because air has mass.
Do heavy basketballs help with dribbling?
Weighted balls can force you to put more effort behind your downward motion when dribbling. The extra push is necessary to have the ball return to the desired dribbling height. Using a heavy basketball during dribbling drills can help build wrist and forearm strength.
Why is my basketball not bouncy?
Basketballs need to be inflated with air to bounce, so when it is flat it doesn’t bounce. When it is properly inflated, it will bounce again and you can play basketball with your friends and family once more. To inflate a basketball, you will need the following: Hand pump with an inflation needle (basketball air pump)
What surface makes a ball bounce higher?
The harder the court surface is the more energy a dropped ball retains and the higher it rebounds. A basketball bounces pretty well on hardwood, but even better on concrete. But, if the floor is too hard, it can lead to serious player injuries.
What energy causes a ball to bounce?
Elastic potential energy is what causes a ball to bounce, or rebound, because it is transformed into kinetic energy, which is then used to bring the ball back up.
What form of energy is dribbling a ball?
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.
What forces are involved in basketball?
You and gravity both apply force on the ball. The ball accelerates toward the ground with the force of gravity. After the ball hits the ground, an equal but opposite amount of force acts on the ball, forcing it back up into your hand.
