The difference between free fall and terminal velocity i that free fall is when an object is falling or descending through the air with little air resistance or drag. Terminal Velocity, on the other hand is when the resistance of air and the force of gravity balance each other out causing the object to reach a constant velocity.

What is the terminal velocity of body in a freely falling system?
Assuming the object starts at rest, it is zero. However, if the object is thrown upward or downward, its inital velocity will not be zero.
What happens as an object falls towards the earth?
It accelerates downward at a rate of 9.8m/s2. Depending on the object and how high above the earth it started, it may reach terminal velocity at which point it will no longer accelerate, but will continue to fall at a constant velocity.
What force is used by bungee jumpers?
Drag from the air increases the duration someone will fall. Also there is a cap speed one can fall at known as Terminal Velocity. These two factors combined allow people to sky dive without instantly hitting the ground.
What is an example of terminal velocity?
An example would be "any object that is moving through the air, water or other substance at a rate such that it cannot possibly go faster without additional force being applied." "Terminal Velocity" in dropping a rock from an airplane might mean "the fastest the rock can possibly fall on its own." Once the rock reached that velocity, it would not be able to go faster despite that it had accelerated to that point without additional force (or increased gravity) being applied to the rock. rock from plane when force down = force up force down = mg (newtons) force up = force of air resistance (velocity ^2* drag coefficient ) newtons. you can use known terminal velocity to calculate drag coefficient if mass is known.
What units are used to measure acceleration in free fall?
(any unit of distance) divided by (any unit of time)2 is a unit of acceleration.The acceleration of gravity is usually expressed in meters/second2 or feet/second2 .
What is the terminal velocity of body in a freely falling system?
Assuming the object starts at rest, it is zero. However, if the object is thrown upward or downward, its inital velocity will not be zero.
What does a parachute do to terminal velocity?
A parachute increases drag, slowing the fall of an object and reducing its terminal velocity. As the parachute deploys, it captures air and creates resistance, causing the object to fall more slowly towards the ground.
How fast can a man fall to earth from airplane?
The fastest rate a human can fall is called terminal velocity. Terminal velocity is when the gravity force upon an object is equal to that of the wind resistance. The normal terminal velocity of a human is around 125 miles per hour.
Can you survive terminal velocity?
Yes, you can survive terminal velocity if you have the proper equipment, such as a parachute, to slow down your fall before reaching the ground. Terminal velocity is the maximum speed an object reaches when falling through the air, and with the right precautions, it is possible to survive a fall from this height.
What is the final velocity?
Perhaps you mean Terminal Velocity, as in a parachute fall? This is the maximum speed reached in the fall. Final velocity will be zero, assuming you arrive on the ground.
Is terminal velocity the same speed for any weight?
Terminal velocity for a feather will be considerably lower than the terminal velocity of a bullet. The size and shape of the object will play an important role. While objects dropped from a given height in a vacuum will fall to earth at the same velocity, the resistance caused by atmosphere will be different for different objects.
Does a skydivers decreases her acceleration when falling 5 seconds before reaching her terminal velocity?
No, a skydiver's acceleration remains constant as they fall towards their terminal velocity. This is because terminal velocity is the point at which the forces of gravity and air resistance are balanced, resulting in a constant velocity.
In free fall when the air resistance is equal to the weight of the falling object we say that the object has reached velocity.?
Yes. When the force of air resistance equals the force of gravity acting on the falling object, the net force on the object becomes zero, causing it to reach terminal velocity. At this point, the object stops accelerating and falls at a constant speed.
What is the definition for terminal velocity?
As an object falls faster and faster it is slowed by friction with the air as it tries to push through. When this wind from falling is so strong that it balances gravity, so the object does not fall any faster, that it is the terminal velocity for that object.
An object is in free fall until it reaches terminal velocity?
During free fall, an object accelerates due to gravity until air resistance balances the gravitational force, reaching terminal velocity. At terminal velocity, the object falls at a constant speed because the air resistance is equal to the force of gravity acting on it.
What is the greatest velocity an object reaches during free fall?
Assuming this is a free fall on the earth, the highest velocity an object in free fall can reach is 9.8 meters per second or 32 feet per second.answer 2. above is described the acceleration due to gravity on Earth.The Q asks for the Highest velocity. This is known as the Terminal Velocity.This depends upon buoyancy, air-resistance and so on. The terminal velocity of a Parachutist is much less than that of a rock. But Terminal Velocity is their greatest velocity.
What happens to an object in free fall can it has a constant velocity?
In free fall, an object accelerates due to gravity until it reaches its terminal velocity, where the force of air resistance equals the force of gravity, resulting in a constant velocity. Once the object reaches terminal velocity, it no longer accelerates and continues to fall at a steady speed.
