What is velocity ?

This animation demonstrates what is velocity ?

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 a physical vector quantity; both magnitude and direction are needed to define it.

What is Velocity class 9th?
Velocity: Velocity is the speed of an object moving in a definite direction. The SI unit of velocity is also metre per second. Velocity is a vector quantity; it has both magnitude and direction.

What is velocity explain with example?
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 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).

What is the final velocity formula?
Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth's gravitational force as the acceleration rate of an object.
