Velocity
An objects velocity is considered to be the rate of change of its position with respect to a
Frame of Reference
, and is a function of
Time
.
Velocity is a concept in
Kinematics
, which concerns motion without regard to the cause or source of that motion.
Velocity is a
vector
quantity, consisting of the magnitude and direction of some object in
Motion
.
The scalar absolute value of velocity is
Speed
.
If there is a change in speed, or direction, then the object has a changing velocity, and can be said to be experiencing
Acceleration
.
Referenced in
Acceleration
Acceleration is the rate of change of
Velocity
of some object in
Motion
, with respect to
Time
.
Lagrangian Mechanics
Newtonian Mechanics presents the motion of systems as comprised of the
positions
,
velocities
, and
accelerations
, of each component of the system.
Motion
Motion is mathematically defined in terms of
displacement
,
Distance
,
Velocity
,
Acceleration
,
Speed
and
Time
.
