When A parachutist reaches it terminal speed?
When a parachutist reaches terminal speed, the force of air resistance pushing up on the parachutist equals the force of gravity pulling the parachutist downward. At this point, the net force on the parachutist is zero, resulting in a constant velocity.
What acceleration does a parachutist have when falling before opening the parachute?
A parachutist falling before opening the parachute experiences an acceleration due to gravity of approximately 9.81 m/s^2, which is the acceleration due to free fall. This acceleration causes the parachutist's velocity to increase as they fall towards the ground.
What kind of energy change takes place when parachutist does falling?
When a parachutist is falling, potential energy from height is converted into kinetic energy as the parachutist accelerates towards the ground. As the parachute is deployed and air resistance increases, some of the kinetic energy is converted back into potential energy, slowing the fall.
Which tow forces are acting on free falling parachutist?
Gravity is pulling the parachutist downwards towards the Earth, while air resistance (or drag) is pushing upwards against the parachutist's fall, slowing down their descent.
What are the directons in which the forces are acting when a parachutist when he is falling?
When a parachutist is falling, the forces acting on them are gravity pulling them downward and air resistance pushing against their fall. Gravity is the dominant force causing the parachutist to accelerate towards the ground while air resistance counteracts this force, eventually leading to a terminal velocity where the forces are balanced.
When a parachutist is moving with a constant speed what happens?
There are two possibilities. One is that he is falling at a constant (positive) speed. In this case, the downward force of gravity is exactly offset by the upward force of drag or air resistance. The parachutist is said to have reached terminal velocity. The second possibility is that he is moving downwards at a constant speed of zero. He has hit the ground! The parachutist may be said to have reached a terminal situation!
Which force stops a parachutist falling to earth uncontrollably?
Upthrust
When A parachutist reaches it terminal speed?
When a parachutist reaches terminal speed, the force of air resistance pushing up on the parachutist equals the force of gravity pulling the parachutist downward. At this point, the net force on the parachutist is zero, resulting in a constant velocity.
Does a parachutist move upward?
No. When you see a video of a parachutist "moving up" it is because the person with the camera is falling faster than the person they are filming.
What acceleration does a parachutist have when falling before opening the parachute?
A parachutist falling before opening the parachute experiences an acceleration due to gravity of approximately 9.81 m/s^2, which is the acceleration due to free fall. This acceleration causes the parachutist's velocity to increase as they fall towards the ground.

Gravity is the dominant force causing the parachutist to accelerate towards the ground while air resistance counteracts this force, eventually leading to a terminal velocity where the forces are balanced.
Would a parachutist be considered a free falling object and why?
The falling of a parachutist without his parachute deployed will be quite fast. We can slow his decsent by putting a drag on the free fall with a parachute. The fall is no longer free of drag (friction).
How does a parachute and air resistance work?
When a parachutist jumps, the parachute deploys and opens up, creating a large surface area. This increases air resistance, which slows down the fall by creating a drag force that counters gravity. The parachute allows the parachutist to safely land at a slower speed than if they were falling freely.
How does air resistance affect the way the parachutist falls?
Air resistance, also known as drag, affects the way a parachutist falls by slowing down their descent. As the parachutist falls, the force of air resistance increases with speed, eventually reaching a point where it equals the force of gravity pulling the parachutist down. This creates a situation known as terminal velocity, where the parachutist falls at a constant speed without accelerating further.
How does the air resistance affect the parachutist's fall?
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.
