Acceleration
Acceleration is the rate of change of
Velocity
of some object in
Motion
, with respect to
Time
.
Acceleration is a
vector
quantity, and the way acceleration is oriented is given by the orientation of the net
Force
acting on the object.
The magnitude of an object undergoing acceleration is described by
Newton's second law
as the result of two causes:
The net balance of external forces acting on the object: magnitude is directly proportional to this net force.
The mass of the object, depending on the materials comprising it, magnitude is inversely proportional to the mass of the object.

Velocity
If there is a change in speed, or direction, then the object has a changing velocity, and can be said to be experiencing
Acceleration
.
Lagrangian Mechanics
Newtonian Mechanics presents the motion of systems as comprised of the
positions
,
velocities
, and
accelerations
, of each component of the system.
Newton's Laws of Motion
For an object with constant mass, the net force acting on the object, is equivalent to the
Mass
of the object multiplied by the
Acceleration
.
Motion
Motion is mathematically defined in terms of
displacement
,
Distance
,
Velocity
,
Acceleration
,
Speed
and
Time
.
