It was learned in the previous part of this lesson that a free-falling object is an object that is falling under the sole influence of gravity. A free-falling object has an acceleration of 9.8 m/s/s, downward (on Earth). ... The numerical value for the acceleration of gravity is most accurately known as 9.8 m/s/s.

Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth's gravitational force as the acceleration rate of an object.

Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing. The acceleration is negative when going down because it is moving in the negative direction, down.

Near Earth's surface, gravitational acceleration is approximately 9.81 m/s2, which means that, ignoring the effects of air resistance, the speed of an object falling freely will increase by about 9.81 metres per second every second.

On the surface of earth the acceleration due to gravity, g = GM/R^2, where, G is Newton's universal gravitational constant M is the mass of the earth and R is the radius of earth. Putting all the values we get, acceleration due to gravity (g)= 9.8 m/s^2.

In physics, gravitational acceleration is the free fall acceleration of an object in vacuum — without any drag. This is the steady gain in speed caused exclusively by the force of gravitational attraction. ... This equality is true regardless of the masses or compositions of the bodies.

Galileo found that the acceleration due to gravity (called ``g'') depends only on the mass of the gravitating object and the distance from it. It does not depend on the mass of the object being pulled.

The acceleration which is gained by an object because of gravitational force is called its acceleration due to gravity. Its SI unit is m/s2 . Acceleration due to gravity is a vector, which means it has both a magnitude and a direction.

Originally Answered: What is the difference between gravity and the acceleration due to gravity? Within Newtonian mechanics gravity is a force. In contrast, acceleration is change in velocity per unit time. Acceleration due to gravity is just that acceleration caused by gravity on a free body.

The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g equal to the conventional value of gravitational acceleration on Earth, g, of about 9.8 m/s2.

The symbol g is often used informally as a unit of acceleration. By agreement among physicists, the standard acceleration of gravity gn is defined to be exactly 9.80665 meters per second per second (m s-2), or about 32.174 05 feet per second per second.

At the surface of the Earth, the acceleration due to gravity is roughly 9.8 m/s2 (32 ft/s2).

If a body is moving with constant velocity, acceleration is zero. So net force acting on it will be also zero. But the body has energy due to its constant motion. Take the case of a freely falling body: it reaches its terminal velocity (120mph) when gravity = air resistance (drag).
