What is the formula for calculating the velocity of an object falling freely under gravity, expressed as v2/2g?
The formula for calculating the velocity of an object falling freely under gravity is v2/2g, where v represents the velocity of the object and g represents the acceleration due to gravity.
When a falling object has reached its teminal velocity its accleration?
When a falling object reaches its terminal velocity, its acceleration becomes zero. The downward force of gravity is balanced by the upward force of air resistance, resulting in no overall acceleration.
Below is the rule for calculating the velocity of a falling object?
If you can ignore the effects of air resistance, then . . .The speed of a falling object isS = s0 + G TS = speed at any time after it's droppeds0 =initial speed you gave it when you dropped it; if you just openedyour hand and let it roll out, then s0 is zero.G =acceleration of gravity; On Earth: 9.8 meters (32.2 feet) per second2T =length of time it has been falling.That's the speed of the falling object, also the magnitude of its velocity.The direction of velocity is on a line toward the center of the Earth, typicallyreferred to in most places as "down".
What is the acceleration of a falling object that has reached it's terminal velocity?
At terminal velocity, the acceleration of a falling object is zero. Terminal velocity is the constant speed that a freely falling object eventually reaches when the resistance of the medium (such as air) through which it is falling equals the force of gravity.
Does the velocity of a falling object increase or decrease?
The velocity of a falling object increases as it falls due to the acceleration of gravity acting on it. As the object falls, it gains speed and accelerates toward the ground until it reaches a constant velocity known as terminal velocity.
What is the formula for calculating the velocity of an object falling freely under gravity, expressed as v2/2g?
The formula for calculating the velocity of an object falling freely under gravity is v2/2g, where v represents the velocity of the object and g represents the acceleration due to gravity.
Are the direction of the velocity and acceleration of a falling body the same?
For the most part, yes; once at terminal velocity, there is no acceleration, so it has direction.
When a falling object has reached its teminal velocity its accleration?
When a falling object reaches its terminal velocity, its acceleration becomes zero. The downward force of gravity is balanced by the upward force of air resistance, resulting in no overall acceleration.
What is the acceleration of falling object that has reached its terminal velocity?
Zero, by definition.
Below is the rule for calculating the velocity of a falling object Use this rule to calculate the rate expressed in feet per second that a piano dropped 3 seconds ago is falling?
The rule for calculating the velocity of a falling object is V = gt, where V is velocity, g is the acceleration due to gravity (32 ft/s^2), and t is time. For an object dropped 3 seconds ago, the velocity would be V = 32 ft/s^2 * 3 s = 96 ft/s.
How is the initial velocity zero but the acceleration is not?
Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]

Are the directions of the velocity and acceleration of a falling body the same?
Yes, both are directed downward.
What is the greatest velocity a falling objecy reaches?
The greatest velocity, achieved when the acceleration due to gravity is balanced by the aerodynamic deceleration, is called the terminal velocity.
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
