By definition, if he is accelerating, then it is an unbalanced force ... which means he JUST jumped out the plane and his downward speed in increasing. Once he reaches a particular speed (called terminal velocity; lets call it for a general case of about 110 mph), the force of DRAG will be equal to the force due to gravity and he will no longer be accelerating, no longer increasing in speed, and he will then have balanced forces.
Since the variables are always changing, drag will change with the most subtle changes in the skydiver's orientation either intentionally or unintentionally and the air resistance is constantly changing with increase in density, the forces will never be truly balanced. The effect of both forces will seesaw between one or the other being dominant. Terminal velocity is achieved when that process is minimal.
It is of note that the effect of gravity itself is changing but over a skydive, the effect is negligible and may be ignored.
kinetic energy
A skier at the top of the mountain has potential energy, which is the energy stored in an object due to its position or state. As the skier moves downhill, potential energy is gradually converted into kinetic energy, the energy of motion.
A skier going downhill on a slope is due to gravity pulling the skier downwards. The angle of the slope causes the skier to accelerate as they descend. By controlling their speed and direction using their skills and equipment, the skier can navigate the slope safely.
To calculate the force needed to accelerate the skier, you need to know the acceleration. If the acceleration is not provided, you can use the formula F = m*a, where F is the force, m is the mass of the skier (66 kg), and a is the acceleration. However, without the acceleration value, the force cannot be accurately calculated.
The force needed to accelerate the skier can be calculated using the formula F = m * a, where m is the mass of the skier (66 kg) and a is the acceleration (2 m/s^2). Plugging in the values, the force required would be 132 N.

Ascending means going up and descending means going down. Ex: The elevator was ascending. The skier was descending the mountain slope.

The forces acting on a skier include gravity, which pulls them downward, and normal force, which is the upward force exerted by the snow. Additionally, friction between the skis and the snow resists motion, while aerodynamic drag opposes forward movement as the skier descends. These forces interact dynamically as the skier navigates slopes and turns.
