gravity is force of attraction that exists between masses , the earth being one (large ) mass , and you , another. Just by standing on the earth the soles of your feet will register the force of attraction between you, although you can overcome the entire earths gravity by(for instance) climbing some stairs.
Although the earths gravity diminishes the further you get away from it, you have to travel a good distance away before you notice the difference, so in practical terms the earths gravity remains constant and about the earths surface will produce an acceleration towards its centre of about 9.8((m/s)/s), that is to say if you drop a stone from a tower its velocity increase will be 9.8m/s over each one second interval, for example:
time from drop(s) velocity(m/s)
0 ----------------------0
1 ----------------------9.8
2 ---------------------19.6
3 ---------------------29.4
see also equation : force = mass * acceleration (issac newton)
so essentially if you apply a constant force (in this case, gravity ) to a mass (stone ), it will gain speed (accelerate) uniformly
Gravity exerts a force on objects; such a force (if not counteracted by some other force) will cause an acceleration, according to Newton's Second Law. The amount of the acceleration can be calculated as a = F/m.
When given a constant acceleration, just multiply it by time, t, to detemine the final velocity. If the initial velocity was zero (as is the case when you drop something), then the average velocity is half the terminal velocity.
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.
Acceleration is the rate of change of velocity - how fast a velocity changes. Therefore, its units are naturally (meters/second) / second, usually written as meters/second2.Acceleration is the rate of change of velocity - how fast a velocity changes.

The rate of change of motion is known as acceleration. Acceleration is the change in velocity over change in time. Velocity is the rate of change of position, or change in position over change in time.

It is about 9.814 meters per second per second on Earth
When given a constant acceleration, just multiply it by time, t, to detemine the final velocity. If the initial velocity was zero (as is the case when you drop something), then the average velocity is half the terminal velocity.
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.
Acceleration is the change in velocity over time.In SI units, acceleration is measured in metres per second squared (m/s2).g is the symbol for the average acceleration produced by gravity at the Earth's surface.The actual acceleration of gravity varies from place to place, depending on latitude, altitude, and local geology.The standard acceleration of gravity g is defined to be exactly 9.80665 meters per square second (m/s2).That is about 32.17405 feet per second squared.
Acceleration is the rate of velocity incerease: > Acceleration = velocity increase / time > Units : metres per second increase per second
9.8 m/s squared is the acceleration due to gravity on earth. So if you drop any object from a certain point it will accelerate at 9.8 m/s squared down.

The rate of change of motion is known as acceleration. Acceleration is the change in velocity over change in time. Velocity is the rate of change of position, or change in position over change in time.
It is the rate of change of velocity. If the velocity changes from five to six meters per second in one second, then the acceleration is one meter per second per second.
For every second of acceleration the velocity is increased by that acceleration.
Velocity (acceleration x time = velocity).
