The forces present in this situation are gravity and air resistance.
In this situation, there are three main forces at play: gravity, air resistance, and the normal force.
Gravity is the force that pulls the skydiver downwards toward the Earth. It is a fundamental force that attracts objects toward each other with a force proportional to their masses.
Air resistance, also known as drag, is the force that opposes the motion of the skydiver through the air. As the skydiver falls faster and faster, the air resistance increases. At a certain point, the air resistance will balance out the force of gravity, resulting in a constant terminal velocity, where the skydiver stops accelerating and falls at a steady speed.
The normal force is the force exerted by a surface to support the weight of an object resting on it. In the case of a skydiver, when they jump out of the plane, there is no surface supporting them, so the normal force is not present.
So, the answer is gravity, air resistance, and normal force.
