నిర్ధిష్ట దిశలో ఒక వస్తువు యొక్క వడిని '''వేగం''' అంటారు. సాధారణ పరిభాషలో వడికి బదులుగా వేగం అనే పదాన్ని తరచుగా ఉపయోగిస్తుంటారు. కానీ భౌతిక శాస్త్రంలో, వస్తువు యొక్క [[స్థానభ్రంశము]]లో జరిగే మార్పు రేటుని '''వేగం''' గా నిర్వచిస్తారు. ఇది పొడవు.కాలం<sup>(-1)</sup>(LT<sup>(-1)</sup>) ప్రమాణము కలిగిన ఒక [[సదిశ రాశి]]. [[యస్.ఐ]] (మెట్రిక్) పద్ధతిలో, వేగాన్ని [[సెకనుకు మీటర్లు]] (మీ/సె)తో కొలుస్తారు. వేగం యొక్క అదిశ [[absolute value]] ([[పరిమాణము|పరిమాణమే]]) [[వడి]].

The instantaneous velocity vector (''v'') of an object that has position ''x''(''t''), at time ''t'', can be computed as the [[derivative]]:
:<math>v={\mathrm{d}x \over \mathrm{d}t} = \lim_{\Delta t \to 0}{\Delta x \over \Delta t}.</math>
 
The equation for an object's velocity can be obtained mathematically by taking the [[integral]] of the equation for its acceleration beginning from some initial period time ''<math> t_0 </math>'' to some point in time later ''<math>t_n</math>''.
 
:<math>v={\int_{t_0}^{t_n} a\,dt}.</math>
 
The final velocity ''v'' of an object which starts with velocity ''u'' and then accelerates at constant acceleration ''a'' for a period of time ''t'' is:
 
:<math>v = u + at.\;\!</math>
 
The average velocity of an object undergoing constant [[Acceleration|acceleration]] is <math>\begin{matrix} \frac {(u + v)}{2} \; \end{matrix}</math>, where ''u'' is the initial velocity and ''V'' is the final velocity. To find the displacement, ''s'', of such an accelerating object during a time interval, ''t'', substitute this expression into the first formula to get:
 
:<math>s = \frac {( u + v )}{2}t.</math>
 
వస్తువు యొక్క ప్రారంభ వేగం (''u'') మాత్రమే తెలిసినప్పుడు ఈ సమీకరణాన్ని ఉపయోగించవచ్చు.
 
:<math>s = ut + \frac{1}{2}a t^2,</math>
 
can be used. These basic equations for final velocity and displacement can be combined to form an equation that is independent of time, also known as [[Torricelli's equation]]:
 
:<math>v^2 = u^2 + 2as.\,</math>
 
The above equations are valid for both [[classical mechanics]] and [[special relativity]]. Where [[classical mechanics]] and [[special relativity]] differ is in how different observers would describe the same situation. In particular, in [[classical mechanics]], all observers agree on the value of ''t'' and the transformation rules for position create a situation in which all non-accelerating observers would describe the acceleration of an object with the same values. Neither is true for [[special relativity]]. In other words only [[relative velocity]] can be calculated.
 
The [[గతిజ శక్తి]] ([[energy]] of motion) of a moving object is linear with both its [[mass]] and the square of its velocity:
 
:<math>E_{K} = \begin{matrix} \frac{1}{2} \end{matrix} mv^2.</math>

==Polar coordinates==
In [[Coordinates (elementary mathematics)|polar coordinates]], a two-dimensional velocity can be decomposed into a radial velocity, defined as the component of velocity away from or toward the origin (also known as ''velocity made good''), and [[transverse]] velocity, the component of velocity along a circle centered at the origin, and equal to the distance to the origin times the [[కోణీయ వేగం]].
 
[[కోణీయ ద్రవ్యవేగం]] in scalar form is the distance to the origin times the transverse speed, or equivalently, the distance squared times the angular speed, with positive quantities representing counter-clockwise direction and negative quantities representing clockwise direction (in a right-handed coordinate system).
 
వేగం = స్థానభ్రంశము (divided by) కాలం
 
If forces are in the radial direction only with an inverse square dependence, as in the case of a gravitational [[orbit]], angular momentum is constant, and transverse speed is inversely proportional to the distance, angular speed is inversely proportional to the distance squared, and the rate at which area is swept out is constant. These relations are known as [[Kepler's laws of planetary motion]]
