what's velocity? what's formula for velocity?
Answers
Answer:
The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion.
- Other units: mph, ft/s
- In SI base units: m/s
- Dimension: L T−1

The meaning of velocity of an object can be defined as the rate of change of the object’s position with respect to a frame of reference and time. It might sound complicated but velocity is basically speeding in a specific direction. It is a vector quantity, which means we need both magnitude (speed) and direction to define velocity. The SI unit of it is meter per second (ms-1) if there is a change in magnitude or the direction in the velocity of a body the body is said to be accelerating.
v=s/t
Where,
s = displacement
t= time taken
