Passing is a very important element in the game of basketball. Passing is the fastest way to get the ball down the court into the opponents end. On this page, I will show you how kinematics, forces, and energy relate to passing a basketball
Kinematics
Kinematics is the study of motion. While passing a basketball, it is important to find out what the right velocity you should pass the ball at, to insure that the ball get to where it needs to. For kinematics, I calculated velocity final to find the acceleration of my pass.

In my givens list, I have displacement, velocity initial, time and the mass of the basketball. With this information, I am able to determine final velocity. Final velocity is solved to me 7.88m/s squared. With initial velocity, and final velocity, i am able to find acceleration using the equation a=vf-vi/t. After plugging in the numbers, I am able to find that the acceleration of the pass is is 6.62m/s.
Forces
Forces of passing a basketball include:
- Force Applied
- Force of Gravity (allows ball to come back down)
- Normal Force (perpendicular to force of gravity)
- Force of friction (when the ball leaves your hand & when another player catches the ball)
Newton's Law's of Motion:
Newtons first law states that an object at rest, wants to stay at rest unless an unbalanced force acts upon in. This can be seen through passing a basketball. A basketball, in a players hands wants to stay at rest, unless a force applied is acted upon in to direct where it wants to go. A ball at rest, has all equal forces, but as soon as a force is being applied, it goes in the direction the force being applied is.
Newtons second law can be seen by the equation F = ma. Acceleration and force can be seen as vectors, meaning in this law the direction of the force vector is the same as the direction of the acceleration vector. It also means that acceleration and force are proportional to each other, the more force acted on an object, the faster acceleration there is. In basketball, the more force you apply to passing a basketball, the faster it gets there.
Lastly, newtons third law states that with every action, there is a equal and opposite reaction. This applies to basketball because while passing a basketball, you push off the basketball with your hand, and the basketball pushes back on your hand with the same amount of force.
In my calculations seen below, i have calculated all applicable forces, and a free-body diagram.

In my calculations seen below, i have calculated all applicable forces, and a free-body diagram.
Firstly, to find the force of gravity, i knew the equation is fg=mag. After plugging in my numbers, i was able to find that fg=6.076N. Secondly, to find FNET, i knew FNET=ma which is 3.162N. To find the force of static friction as the ball leaves the hand for a pass, i searched the coefficient of friction of leather to skin. The coefficiant is 0.3. After mutiplying the coefficient of fricktion and the normal force, the force od static friction max is 1.82N. From this, i can determine the force applied by using the equation FNET+Fs(max)=FA. FA is calculated to be 4.89N. The free body diagram shows all applicable forces and their amount of force in Newtons.
Energy & Power
While passing a basketball, it is important to know that work is the change in energy that basketball is performing, and power is that rate at which the basketball is doing work. Work and power work together to make sure the basketball gets to where it needs to be. In my calculations, i have shown how much work and power is needed to complete a pass that is 6.08m away.

Therefor, I know this athlete must have 19.39J of energy and 16.29W of power to complete a pass that is 6.08m away.
