Near the surface of the Earth, the rate of acceleration due to gravity is equal to 32 feet per second per second, or 9.8 meters per second per second. That means that if you release an object from a tall tower, the object will fall.
After one second, it will be traveling at 32 feet per second, and will have traveled 16 feet. After 2 seconds, it will be traveling at a speed of 64 feet per second, and will have fallen 48 feet. In the absence of air resistance, the object will continue to accelerate at this rate, speeding up until it hits the ground.
Far from the Earth, the acceleration of gravity depends on the distance to the object; the force of gravity falls off by the square of the distance.
Around other planets or moons, the force is proportional to the mass of the planet.
Assuming standard Earth gravity, and if there is no air resistance, an object will fall down faster and faster - its speed will increase at a rate of 9.8 meters/second every second. This is usually expressed as 9.8 meters/second2.
In the absence of air resistance, a body falling to Earth would accelerate at a rate of approximately 9.8m/s2; gaining 9.8 metres per second velocity every second.
9.8m/s2
Both objects would eventually reach terminal velocity which means they would both fall at the same speed.- But - compared to the falling object, the downward acceleration of a thrown object is the same.
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
The acceleration due to gravity for an object near the surface of the earth is approximately 9.81 m/s^2, but we can generalize this to "all falling objects" by defining falling as being attracted toward more massive object by gravitational force alone. The attractive force between the objects in this case is described by Newton's law of universal gravitation: F = G*m_1*m_2/r^2 where G = 6.67*10^-11, m_1 and m_2 are the masses (in kilograms) of the two objects, and r is the distance (in meters) between the centers of mass of the objects. The units of G are a little complicated, but this expression simplifies to units of meters/second^2, which is acceleration. Because the mass of a planet is so great compared to the mass of any object on its surface, the value of F does not change by a significant amount whether the falling object is a whale or a bowl of petunias.
Acceleration is a net force that is inversely dependent on mass, therefore if an object's mass decreases, acceleration increases.
If you increase the force on an object acceleration increases . As F = m*a, where F = Force , m = mass of the object & a = acceleration
rate of acceleration
-- The rate of acceleration of an object on the moon is(the net force on the object)/(the object's mass) .-- If the object is falling, with nothing but the force of gravity acting on it, thenits acceleration is 1.623 m/s2 (compared to 9.807 on Earth).
Acceleration of a falling object is directly proportional tothe force of gravity in the object's location.
It reduces the acceleration of the falling object due to friction.
The acceleration of a falling object is called gravity. A free-falling object has an acceleration of 9.8 m/s/s when going downward on Earth.
Acceleration
On Earth, a free-falling object has an acceleration of 9.8 meters per second2.

Gravity
Acceleration. A free-falling object falls at constant force, and thereby at constant acceleration.
Newton's Second Law of Acceleration says it is gravity.
