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.
What is the fastest an object can fall through the sky?
The fastest an object can fall through the sky is at its terminal velocity, which is when the force of gravity is balanced by air resistance. For most objects, this speed is around 120 mph (193 km/h) for a human in freefall. However, the exact speed can vary based on factors like air density and the object's shape.
Will density of a substance cause it to fall faster?
All objects fall at 32 feet per second per second, meaning that every second, they are falling 32 feet per second faster. Air resistance may have a minimal effect but the density of the object will not affect the speed.
What most determines how fast an object will fall on earth?
The acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth, is the primary factor that determines how fast an object will fall. Objects will fall faster if they have a higher acceleration due to gravity and slower if they have a lower acceleration due to gravity. Other factors like air resistance and the density of the object can also have a small effect on the speed of fall.
How is speed affected by gravity?
Gravity acts as a barrier and slows it down. However, if you say, jump of a building. When you fall gravity will speed you up and you'll be dead fast. When you fall your speed is about 78mph. But that depends on the height of the building and wind direction.

What will happen if object falls from great height through air of uniform density?
It will fall faster and faster for a while - until it eventually reaches a "terminal speed", at which air resistance and gravity are in balance. After that, it will continue falling at a constant speed.
Why don't objects fall to earth at the same velocity?
Air resistance of an object can slow its fall. If every object had the same resistance, everything would fall at the same speed.
When an object reaches its termainal speed its acceleration is zero right?
Yes, when an object reaches its terminal speed, the acceleration becomes zero because the forces acting on the object (such as air resistance) have balanced out the force of gravity causing the object to fall at a constant speed. This constant speed is the terminal speed of the object.
What is free fall fall?
An object is in free fall only if its motion is subject to being both only affected by gravity and only moving up or down.
Suppose an object in free fall is dropped from a building Its starting velocity is 0 Ignoring the effects of air resistance what is the speed of the object after falling 3 seconds?
The speed of the object after falling for 3 seconds in free fall is 29.4 m/s.
Who does the weight of an non-free fall opject compare with the air resistance when it is in its termenal speed?
In an object in terminal speed, the weight of the object is equal to the air resistance acting on it. This balance of forces allows the object to fall at a constant speed, as the downward force of gravity is exactly countered by the resisting force of the air.
An object launched from Earth must attain a speed of 7900 m per second to achieve a low orbit What happens if the object its maximum speed is less than 7900m per second?
If the object's maximum speed is less than 7900 m/s, it will not reach a low orbit and will fall back towards Earth due to gravity. To achieve a stable low orbit, an object needs to reach the necessary speed to counteract the gravitational pull and continuously fall towards Earth.
