Velocity Formula
There are different formulas to calculate the velocity of an object using different parameters under various conditions. Here are some of the major formulas used to calculate different velocities as-
When the initial (xi) and the final position (xf) of an object along with the time interval are given, then the velocity can be calculated as,
Now, according to the Equations of motion, the velocity can be evaluated,
- When initial velocity, acceleration, and time are given then the final velocity is given as,
where
- v is the final velocity,
- u is the initial velocity,
- a is the acceleration and
- t is the time taken by the object.
What is Velocity?
Velocity is an essential concept in physics, which measures the rate of change of an object’s position with respect to time. When the speed of an object is measured in a specific direction, then it is termed Velocity. Also, the time-rate change of displacement is known as velocity. Both speed and velocity are quite similar to each other. But exhibits an important difference in that velocity is a vector quantity that has both magnitude and direction. And speed is a scalar quantity that has magnitude only. Thus, Velocity is a measure of how much time a body takes to reach a destination with direction.

For example, when two objects are traveling in the same direction, then it is easier to tell the faster. But, if the direction of motion of the two objects is in the opposite direction, then it is difficult to identify the fastest. In such situations, the concept of velocity is essential.
