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).
Why do skydivers spread out their arms and legs while they are free falling?
so that they go slower because if u go skydive like ur diving in a pool, u go very fast and might not be able to pull out ur parachute.
Explain why a man using a parachute falls through air slowly while a stone falls through air very fast?
When an object falls through air, it experiences air resistance. This air resistance is a force that opposes the object's motion. The amount of air resistance an object experiences depends on the object's shape, size, and speed. A man using a parachute falls slowly because the parachute creates a large amount of air resistance. A stone falls very fast because it has a small amount of air resistance.
How does a parachute reduce the effect of gravity?
A parachute reduces speed from the air moving up hitting the canvas and having nowhere to go but to the left and right, its like a cushion. You imagine a car going along at 100km/h and then hitting a wall, that is pushing one force against another, something has to give or slow down. If the car is going fast enough the wall will break but the vehicle will most likely be crumpled beyond repair. Therefore a parachute is pitting one amiable force against another amiable force therefore slowing a persons (or whatever else) descent.
How fast is the acceleration of a falling body?
if body is free falling state its acceleration would be 9.8meter/second2

Why a person without a parachute falls fast than a person without a parachute falling from same height?
if there is no air then both will take same time.But due to presence of air person who is without parachute will take less time.
Is it sky diver will come down only with parachute?
Only if he's wearing one.A skydiver will come down, one way or another, due to Earth's gravity. The parachute is to avoid him falling too fast. If he doesn't have a parachute, he will probably die when he crashes on the ground.
How will friction affect a parachute?
How fast it flies down
How fast do skydivers fall through the the air?
A skydiver, falling without an open parachute, will reach a terminal velocity of approx 200 km per hour (55 metres/second).

How fast can the human body go downhill?
At about 180 mph if you fall out of an aeroplane with no parachute.
If you drop a rock from a great height about how fast will it be falling after 5 seconds neglecting air resistance?
The object will be falling at 49 m/s.This is solved by multiplying the force of gravity (9.8 m/s) by the time you're calculating (5s).
Is it true that the thing that affects how fast it falls is the objects surface area?
Surface area is ONE thing that can affect how fast an object falls. Two forces determine how fast an object falls - the force of gravity and the opposing drag on the object from the medium it is falling through. In the case of an object falling in a vacuum, there is no drag so the object falls strictly according to the law of gravity. If an object is dropped through a fluid such as air or water, it can reach a terminal velocity where the force of gravity is exactly counterbalanced by the opposing drag on the object. In this case acceleration ceases - although motion does not. In other words, the object continues to fall, but it doesn't speed up. Drag force is a function of object velocity, viscosity of the fluid it is falling through, the surface area of the falling object, the surface roughness of the falling object, and the geometry of the falling object (spheres usually have less drag than cubes for example).
What does the vent on the top of the parachute do?
The vent on top of the parachute helps air go through. If you didn't have a vent at the top you would be floating in the same place. The vent makes the parachute go down slowly but not fast enough to where you would drop.
