Velocity is quickness of motion or action. A synonym is celerity; a simpler word is speed. In physics, velocity specifically refers to the measurement of the rate and direction of change in position of an object. It is a vector quantity that specifies both the speed of a body and its direction of motion.

Answer 2

Answer:

A body is said to be in velocity if the body displace path with respect to time .

Explanation:

• velocity is a vector quantity.
• Velocity can be Zero and can be negative .Example :-A body moving in straight path with uniform velocity and again come back to its initial path then body having velocity zero since displacement is 0 .If body move more in oposite direction with respect to initial path then body having velocity negative .
• negative sign indicate direction of body .
• Si unit of velocity is m/s And diemension is LT^-1 .
• The line which form in graph When x -axis is displacement and y is time then line form in between them is velocity .
• Velocity is said to be uniform if it cover equal distance with same interval of time .
