ACCELERATION
Definition:
Units:
Average Acceleration
Instantaneous Acceleration

The acceleration is Not a measure of the rate of movement of and object in space. It measures how fast an object's speed is getting faster (or slower). In fact it is possible for an object to be at rest at some moment and till have an acceleration even though it has no speed at that moment - see Sign of the Acceleration.Typical

Equations for Constant Acceleration
Calculus Relationship
An object's instantaneous acceleration function a(t) is the derivative of the object's velocity function v(t) with respect to time.
Velocity-Time Plot
The acceleration of an object at some moment "t" is the slope of the object's velocity function v(t) at that moment. This means that a(t) at t is tangent to velocity versus time curve.
