It is air resistance which slows the rate at which a parachutist falls, turning what would otherwise be a fatal fall into a controlled landing.
What else can I help you with?
Why parachutists do not fall with constant accelerating motion?
Due to air resistance as the resistance is directly proportional to the speed but at certain speed called transitional speed or critical speed the resistance become directly proportional to square the speed so the resistance increase decreasing the falling speed.
What are the factors that affect the speed of an object in free fall with air resistance?
The factors that affect the speed of an object in free fall with air resistance are the object's mass, the surface area of the object, the density of the air, and the gravitational force acting on the object.
How are parachuters air restance?
Parachutists experience air resistance as they fall through the air, which slows their descent and helps to control their speed. The parachute creates drag by catching the air and increasing surface area, which allows the jumper to descend safely to the ground at a controlled rate. This air resistance counteracts the force of gravity pulling the parachutist downward.
Is an object in free fall with less air resistance fall with a greater acceleration?
No, an object in free fall experiences the same acceleration due to gravity regardless of its shape or size. Air resistance does not affect the acceleration due to gravity acting on the object.
How does ball size affect the time it takes the ball to fall?
The size of a ball does not directly affect the time it takes to fall in the absence of air resistance. In a vacuum, all objects would fall at the same rate regardless of size. This is known as the principle of acceleration due to gravity.
Does free fall occur only when air resistance does not affect the motion of a falling object?
Yes, unless speaking about parachutists who refer to free fall as falling through the air without opening their parachutes.
Why parachutists do not fall with constant accelerating motion?
Due to air resistance as the resistance is directly proportional to the speed but at certain speed called transitional speed or critical speed the resistance become directly proportional to square the speed so the resistance increase decreasing the falling speed.
Can Parachutists reduce their air resistance by increasing the size of the cross-section they present to the air?
no, the reverse, you will increase it

The factors that affect the speed of an object in free fall with air resistance are the object's mass, the surface area of the object, the density of the air, and the gravitational force acting on the object.
How does air resistance affect way objects move?
well air resistance can make objects with a-lot of surface fall more slowly

How does air affect how fast things fall?
Air resistance is basically friction between the object on the air- it has to push the air out of the way, and slows down.
Is an object in free fall with less air resistance fall with a greater acceleration?
No, an object in free fall experiences the same acceleration due to gravity regardless of its shape or size. Air resistance does not affect the acceleration due to gravity acting on the object.
How do parachutists reduce the friction?
Parachutists reduce friction by using a smooth parachute fabric and deploying it properly to maximize air resistance, which slows down their descent. Additionally, they can also control their body position to minimize surface area exposed to the air, thereby decreasing friction.
How does ball size affect the time it takes the ball to fall?
The size of a ball does not directly affect the time it takes to fall in the absence of air resistance. In a vacuum, all objects would fall at the same rate regardless of size. This is known as the principle of acceleration due to gravity.
How does mass affect a projectile if there is no air resistance?
In the absence of air resistance, mass does not affect the motion of a projectile. All objects fall at the same rate regardless of their mass in a vacuum. This principle is described by Galileo's law of falling bodies.
Explain why parachutist and snowflakes donot fall with a constantly accelerating motion?
Parachutists and snowflakes do not fall with constantly accelerating motion because of air resistance. As they fall through the air, they experience a drag force that counteracts the force of gravity, eventually reaching a terminal velocity where the forces are balanced and they fall at a constant speed. This prevents them from accelerating indefinitely.
