hi, i am doing a class project and i need to know the physics of skydiving, including momentum impulse and collisions, can someone help me out?!
THANKS BALLERS

Unless you get it wrongMath Jeans said:Momentum and impact are hardly important.
Skydiving involves two main forces: gravity and air resistance. When a person jumps out of a plane, they accelerate towards the ground due to the force of gravity. However, as they fall, the air resistance increases, eventually reaching a point where it balances out the force of gravity, resulting in a constant terminal velocity.
Air resistance, also known as drag, is the force that opposes the motion of a falling object. As a skydiver freefalls, they create a larger surface area due to their body position, increasing air resistance. This results in a decrease in acceleration until the two forces are balanced, and the skydiver reaches a constant speed.
Terminal velocity is the maximum speed an object can reach while falling due to the balance of air resistance and gravity. In skydiving, it is achieved when the forces of air resistance and gravity are equal, resulting in a constant speed of approximately 120 miles per hour for a typical skydiver.
The height of the jump affects the initial speed and time it takes for a skydiver to reach terminal velocity. The higher the jump, the longer it will take for the skydiver to reach a constant speed due to the increased distance they have to fall. However, the physics of the descent, including terminal velocity, remains the same regardless of the jump height.
The body position of a skydiver affects the amount of air resistance they experience, which in turn impacts their descent speed. A spread out body position will create more air resistance and result in a slower descent, while a streamlined position will minimize air resistance and result in a faster descent. Changing body positions during a skydive can also affect the stability and control of the skydiver in the air.
