Question

What is the meaning of velocity

Answer 1

${\fbox{\boxed {\huge{\rm{\red{Answer!!}}}}}}$

∆Velocity:-

Velocity is defined as a measurement of the rate and direction ofvector motion. Put simply, velocity is the speed at which something moves in one direction. The speed of a car traveling north on a major freeway and the speed a rocket launching into space can both be measured using velocity.

∆Velocity Formula:-

${\rm{. r = \frac{d}{t}}}$

• r is the rate or speed (sometimes denoted as v for velocity)
• d is the distance moved
• t is the time it takes to complete the movement

∆Unit of Velocity:-

The SI (international) units for velocity are m/s (meters per second), but velocity may also be expressed in any units of distance per time. Other units include miles per hour (mph), kilometers per hour (kph), and kilometers per second (km/s).

Answer 2

Answer:

— The rate of change of displacement is know as VELOCITY.

$velocity = \frac{displacement}{time \: taken}$

— It is a vector quantity.

— Velocity contains both magnitude and direction.

— The S.I units of velocity is m/s.
