n this page, the physics behind everything in badminton will be investigated. Firstly, the concepts will be explained, and then how the concepts affect the sport will be described.
AERODYNAMICS
Aerodynamics is the study of forces and the resulting motion of objects through the air. Air resistance, or drag, is studied mainly, where the forces acting upon a moving object in air are analyzed. Factors such as velocity, pressure, density and temperature affect drag. Drag is generated when a solid object moves through a fluid medium such as water or air. Drag is proportionate to velocity. A formula in aerodynamics, for drag, is acceleration=(Weight-Drag)/Mass. As an object accelerates, its velocity and drag increase, eventually to the point where drag becomes equal to weight, in which case no more acceleration will occur. A term used in aerodynamics to describe how easily an object moves through the air is the drag coefficient (like u in friction). drag coefficient = drag/(Density*1/2*Velocity^2*Area)
KINETIC ENERGY & POTENTIAL ENERGY
The kinetic energy of an object is the energy it possesses due to its motion. It is defined as the amount of work needed to accelerate the object of the given mass to its stated velocity.

Potential energy is the stored energy of position possessed by an object. An object can store energy from a position. For example, when a bow and arrow is drawn (held back) it will have a lot of potential energy.
MOMENTUM
Momentum can be defined as mass in motion. All objects have mass, so if an object is moving, it will have momentum. The amount of momentum an object has is dependent of 2 things, how much of it is there, and how fast most of it is. Momentum=mass*velocity.
TENSION
Tension is the pulling force exerted by a string, cable, or other-like solid on another object. Tension is an elastic force that stretches and pulls matter. Force is any influence that causes an object to undergo a certain change in either its movement, direction or geometrical construction. Tension is measured in Newtons, and a high tension string vs a low tension string can result in change in your badminton shot and swing.
NEWTON'S LAWS OF MOTION
Newton's 1st law states that an object will continue to move with the same velocity, or continues to stay at rest until and unless a non-zero net force is applied to it.

Newton's 3rd law states that every action has an equal and opposite reaction.
GRAVITY & GRAVITATIONAL POTENTIAL ENERGY
Gravitational potential energy is the energy an object possesses and has stored as a result of its vertical position, and place in the gravitational field.
VELOCITY
Velocity is the rate of change of the position of an object. it is measured specifically with speed and direction of movement. It differs from speed in that it describes the direction of the movement as well as the speed. V=d/t, etc.
PROJECTILE MOTION
Projectile motion is a form of motion where an object (or projectile) is near the earth's surface and it moves along a curved path under the action of gravity. The object will have a flight trajectory in the shape of a parabola. (Formulas don't account for air resistance and drag which is aerodynamics)

How these concepts affect the sport:
BIRDIE
Aerodynamics & Projectile: The birdie is designed to be stable in flight, with its symmetrical cone-like shape. The feathers or plastic ''wings or skirt'' behind the main rounded mass of nylon or rubber are what help stabilize the flight. However, with this said, if the feathers or plastic become damaged, the birdie will not fly properly - it will wobble. Aerodynamically, the birdie was designed to be a high-drag projectile. The high-drag is a result of the plastic skirt behind the birdie. The reason behind this skirt, and the high drag is so the shots will not be so fast that it is unmanageable. For example if I throw a small ball at the same velocity as this birdie, the birdie will be slower.
RACQUET
Tension: To analyze the tension in badminton racquets, the strings in the head of the racquet must be analyzed. How the strings are strung across a racquet face are likewise crucial to the game because the tension of the strings can affect your control of the birdie. With a high tension string, you will have a stiffer string bed. In this case, the birdie will almost instantaneously bounce off your racquet. However with a higher tension, the sweet spot (every racquet has one) will get smaller. This is used mainly by more professional and advanced players as they do not need more of a sweet spot (they already will consistently hit the birdie well), instead they will trade this off for more quick control, which they will need in better competition. With a lower tension string, you will have a looser string bed, and therefore a larger area where you will hit the sweet spot. When the birdie hits the string bed, there is more elasticity in the swing, and the birdie will travel further and with a higher speed. If someone with low tension strings hit a smash with normal power, it will go faster and harder than a person using high tension strings, but with the same amount of power. The elasticity and flexibility of the strings help you with speed of the shot. This bouncy affect can help in terms of speed, but some players find it more difficult in controlling shots, as the extra bounce factor is sometimes hard to control. A higher tension of strings results in faster and quicker control in the shots, while a low tension of strings results in a bouncier shot with more elasticity to help in velocity.

Momentum: For the swing of the racquet, it's momentum has to be enough to overcome drag. This is why badminton racquets are thin and light. Since the mass of the racquet affects the speed at which a player can swing it, with the heavier the racquet the harder to swing, badminton racquets were created to be light and easy to swing and make a high velocity. Badminton wouldn't be the fastest racquet sport in the world if the players were swinging heavy racquets! This is also why badminton racquets are made of material such as carbon fiber and titanium. These materials are used to keep the racquets at a light mass, which would therefore make it easier for the players to swing with greater velocity. The small head was also designed in this way for this purpose. The design of the badminton racquet was created mainly so players can swing with more velocity and to have enough momentum to counter drag and hit the birdie fast.
IN A RALLY
Aerodynamics & Projectile: in a rally, the birdie does not ever travel in perfect projectile motion (parabola). This is because of aerodynamics. There is always drag acting upon the badminton birdie, as it was designed to be a high drag projectile. There is a lot of drag on the birdie due to the skirt behind the nylon tip. Since the nylon tip is the heaviest part, the nylon tip will always be facing forward in direction. This causes the skirt to always be creating drag in motion. As drag increases, velocity will die out and the birdie will start falling towards the ground with the force of gravity.

Kinetic Energy & (Gravitational &) Potential Energy: In a rally, the birdie gains kinetic energy everytime it comes into contact with the racquet's strings in a swing. As the bird flies through the air, it loses kinetic energy and gains potential energy. When it reaches the highest point of its flight trajectory, all of its kinetic energy will have been converted into potential energy. This is because at this point, it is at it's maximum height and there will be the most gravitational potential energy at this point; it is the highest point in the trajectory. As the bird goes down and is hit again by the opponent, the same process will occur again. Pe will turn into Ke once again.

Newtons 1st Law of Motion: This is very simply applied to badminton. The birdie will not move, until net force is applied onto it.

Newton's 3rd Law of Motion: Since the initial action is the badminton racquet swinging, the opposite reaction is the birdie flying through the air.

Velocity in Projectiles: A high velocity of the birdie in a rally can have either a far distance, or short time. However this all depends upon the angle of the projectile, as seen in the experiment. Velocity does not always determine displacement. The smash had the highest velocity but did not travel too far. This is because the initial angle the projectile was launched at was downwards, so the birdie had nowhere to go but to the floor. In this case the velocity being high was good, so it was harder for the opponent to get. However in the case of the clear, the displacement was larger than that of the smash, but velocity was not as fast. This is because of the angle the projectile was launched at. This shows the importance of theta, at the point of impact. Velocity is important in enhancing one's shots to be more effective, but velocity is not always the most important factor.
