What causes a parachute jumper to slow down?
A parachute jumper slows down due to air resistance pushing against the open parachute. As the parachute increases in surface area, it creates more drag, which counteracts the force of gravity pulling the jumper down. This results in a gradual decrease in speed until the jumper reaches a safe landing velocity.
What type of friction is a man falling out of an airplane in a parachute?
The man falling out of an airplane with a parachute is experiencing fluid friction, as the air molecules slow down the descent of the parachute due to air resistance.
How does friction affect the descent of a parachute?
Friction between the air and the surface of a parachute slows down its descent by creating drag force, which opposes the force of gravity. This drag force increases as the parachute travels faster, eventually reaching a point where the forces balance out and the parachute reaches a constant speed called the terminal velocity. Friction is a crucial factor in ensuring a safe and controlled descent for a parachute.
What are the action and reaction forces on the fabric of a parachute when it is deployed?
When a parachute is deployed, the action force is the air resistance pushing against the parachute fabric. This air resistance is created by the change in the air's velocity as it passes through the canopy of the open parachute. The reaction force to this action force is the drag force created by the parachute pulling against the jumper. This drag force is created by the increase in the parachute's surface area, which slows the jumper down as they fall. The drag force is also responsible for the parachute's ability to slow the jumper's descent enough to safely reach the ground.
When a pendulum swings and is not continuously pushed it will stop because some of its energy was changed into what?
When a pendulum swings and is not continually pushed, the energy is gradually lost to friction and air resistance, causing the pendulum to slow down and eventually stop. This lost energy is converted into heat due to the friction between the pendulum and the air or any other surfaces it comes in contact with.

What is a ripcord?
A ripcord is the part of a parachute pulled when the jumper is in the air to deploy the parachute canopy. (i.e., It opens the parachute when pulled)
What type of friction is a man falling out of an airplane in a parachute?
The man falling out of an airplane with a parachute is experiencing fluid friction, as the air molecules slow down the descent of the parachute due to air resistance.
How does friction influence the descent of a parachute?
The cloth surface area and the air rubs together causing friction or drag which slows the parachute down.
What type of friction will you create when you let go of a parachute in the air?
Air resistance.
What type of friction when you will create when you let go of a parachute in the air?
Air resistance.
A pendulum set in motion eventually stops because?
1). Air resistance 2). Friction in the pivot. These two effects rob energy from the pendulum. Without air resistance or friction in the pivot, a pendulum, once set in motion, would not stop.
When a pendulum stops swaying and its at rest has it loss energy?
Yes. Pendulum lose energy due to friction with the air.

Does air resistance help a parachute slow down?
Of course it does. If there was no air resistance then the parachute would accelerate at the speed of gravity which is 9.8m/s/s. If a human were using a parachute and there was no air resistance then they would die. "Air resists the motion of objects traveling through it because its molecules collide with the molecules of the object. This resistance to the motion is beneficial because the force acts to slow down a parachute jumper's speed of fall. The jumper falls with increasing speed until the parachute is opened. The greater air resistance acting on the surface of the parachute will bring the jumper to a terminal velocity and will enable the parachutist to safely reach the ground".http://amyallen.org/mhs/applied_physics/physics_of_flight/rocket/parachutes_payloads.pdf
