Question

what is velocity of an object​

Answer 1

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

Answer 2

Answer:

• Velocity it is the speed of a body in a given direction velocity is displacement upon time.

Relative terms:

Acceleration :

• Acceleration is seen in non uniform motion and can be defined as the rate of change of velocity with time

Speed :

• Speed is defined as the rate of change of position of an object in any direction speed is distance upon time.

Deaccleration or retardation :

• It means negative acceleration.

Formulas

• Acceleration = (v - u)/t
• Speed = Distance / Time
• Velocity = Displacement / Time
• Displacement = v - u = 2as
• Average speed = Total distance covered / Total time taken
• Average velocity = Final velocity + initial velocity / 2

Where,

• a = acceleration

• v = final velocity

• s = Displacement

• u = initial velocity
