Ignoring damping effect what will be the velocity of a free falling body near earth's surface?

Any 'damping effect' is the result of air resistance.
In the absence of air, the velocity of a free falling body near the earth's surface is always directed downward,
and is 9.8 meters (32.2 feet) per second greater, at any instant, than it was one second earlier.

What is the velocity of a 4.5 Pound object falling thirty feet?
Ignoring air resistance ... Any object dropped near the Earth's surface reaches a speed of 43.9 feet per second after falling 30 feet. The velocity is 43.9 feet per second down. The object's weight makes no difference.
What is change in the velocity of a falling object?
Any change in the velocity of anything is known as 'acceleration'. In the case of a falling object near the Earth's surface, the direction of the velocity is constant, and its magnitude increases by 9.8 meters (32.2 feet) per second, every second.
In freefall do all objects near Earth's surface have the same acceleration?
Without atmospheric drag, all free falling objects near earth's surface will have the same acceleration. But because of friction with the air (air resistance), the velocity of objects due to that acceleration is limited. The actual velocity is dependent on the surface area of the object relative to its mass. The principle of the parachute is to increase the surface area of a falling object with respect to its mass.
How does a parachute reduce the terminal velocity of a person falling through the air?
The parachute increase the surface area and so therefore increase air resistance, slowing the person down, and reducing terminal velocity.
What is the velocity of the object falling toward the surface of the earth?
The direction of the velocity is always downward, but its magnitude keeps growing. It's always 9.8 meters per second faster than it was one second earlier.

How does surface area affect damping of an oscillation?
The larger the surface area, the larger the damping of an oscillation

What equation is used to calculate the velocity of a falling objects?
32 feet / second / second. Calculating the velocity of an object falling due to gravity is a complicated process because gravity decreases the further above the Earth you go. There is also a terminal velocity because of the viscosity of the air. Simply though, acceleration due to gravity at the Earth's surface is roughly 9.8m/s2. This means, after 1 second, an object will have achieved a velocity of 9.8m/s. The equation then if the viscosity of air and height above the Earth's surface are ignored is V = 9.8 x S Where V is the velocity and S is the number of seconds it has been falling.
What is the velocity of the object falling toward the surface of the earth?
The direction of the velocity is always downward, but its magnitude keeps growing. It's always 9.8 meters per second faster than it was one second earlier.
The tangential velocity of an Earth satellite is its velocity?
parallel to the surface of the Earth
What is the name of the greatest velocity a falling object can reach?
Terminal velocity. It occurs when the force of gravity is equal to the force applied by air resistance in the opposite direction. With equal and opposite forces the object can not accelerate and falls at a constant speed. Every object has a different terminal velocity and depending on the surface area, can also be manipulated
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 is verlocity parallel to the earht's surface called?
Velocity (not verlocity) parallel to the earth's (not earht's) surface is called the horizontal component of the velocity.
What in sound energy?
