What else can I help you with?
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 the weight of an object relate to how fast it falls with a parachute?
The weight of an object affects how quickly it can reach its terminal velocity when falling with a parachute. Heavier objects typically reach terminal velocity faster than lighter objects due to the greater force of gravity acting on them. However, once both objects reach terminal velocity, they will fall at the same constant speed regardless of their weight.
Does the area of a parachute affect how fast it falls?
Yes, the area of a parachute directly affects how fast it falls. A larger parachute will create more air resistance, slowing down its descent, while a smaller parachute will fall faster due to less air resistance.
What force is used to generate hydroelectricity?
Hydroelectricity is generated by the force of flowing or falling water, typically from a dam or a waterfall. This force is used to turn turbines connected to generators, converting the kinetic energy of the water into electricity.
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.

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).

Hydroelectricity is generated by the force of flowing or falling water, typically from a dam or a waterfall. This force is used to turn turbines connected to generators, converting the kinetic energy of the water into electricity.
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).
