How do you calculate the velocity and acceleration of falling objects?

As usual when we talk about falling objects, we have to ignore air resistance,
because its effects depend on the size, shape, and composition of the object
that's falling, as well as the temperature, pressure, humidity, and wind-speed
of the local air, and we have none of that information. So we must simply treat
the whole subject as if the only effects on the falling object are those that are
the result of gravity.
Velocity:
-- The direction of the velocity vector is down.
-- The magnitude of the velocity vector (called "speed") is
(initial downward speed when dropped or tossed) plus (acceleration x time spent falling).
Acceleration:
-- Direction of the acceleration vector is down.
-- Magnitude of the acceleration vector depends on what planet you're on or near,
but is always the same as long as you stay there, and doesn't need to be calculated.
In the case of Earth, it's 9.8 meters (32.2 ft) per second2 .

How can you calculate the velocity and acceleration of falling objects?
Acceleration:Always the same, doesn't need to be calculated. Acceleration of gravity = 9.8 meters (32.2 ft) per second2Acceleration of gravity is negative (points down).Velocity:(Initial velocity) + [ (acceleration) x (time) ]Positive velocity = moving upNegative velocity = moving down
Formula for acceleration of all objects falling to the earth?
a=change in velocity time
How do you calculate an objects acceleration?
Acceleration is an object's change in velocity divided by its change in time. So: acceleration=(final velocity - initial velocity)/(final time - initial time)
What is the objects acceleration from 0 to 1 second?
Acceleration is the change in velocity over a time period. Since you need to know the change in velocity to calculate acceleration, the question being asked is not answerable.
How do you calculate the acceleration of falling objects?
Ask around to find out what planet they're falling on.If it's the earth, then the acceleration is 9.8 meters (32.2 feet) per second2.
What is the speed at which the acceleration of a falling objects falls to zero because air resistance balances its weight?
This is known as terminal velocity.
What do you call it when an objects velocity changes?
A change in an objects velocity is called acceleration. Velocity is defined as an objects speed of travel AND its direction of travel. Acceleration can change only an objects speed, only its direction or both. If there is no acceleration acting on the object, then the velocity remains constant.
Is it possible for an objects velocity to be perpendicular to the objects acceleration?
no
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.
Why does gravity make falling objects fall faster?
By Newton's Second Law: force = mass x acceleration, or acceleration = force / mass. Since there is a force, there should be an acceleration - a change of velocity.
When falling objects no longer accelerate?
A falling object no longer accelerates, due to friction in the atmosphere, when the friction buildup equals gravity's acceleration. This is called it's terminal velocity.
Acceleration of a falling coin on tower?
The acceleration of falling objects in Earth is about 9.8 m/s2.
