Question

what is speed and velocity​

Answer 1

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 equivalent to a specification of an object's speed and direction of motion.

speed

In everyday use and in kinematics, the speed of an object is the magnitude of the rate of change of its position with time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.

Answer 2

Answer:

Speed is the distance traveled per unit of time. It is how fast an object is moving. Speed is the scalar quantity that is the magnitude of the velocity vector. It doesn't have a direction. If it isn't moving at all, it has zero speed.

Velocity is the rate of motion, speed or action. An example of velocity is a car driving at 75 miles per hour. ... Velocity is a vector quantity.

velocity formula

Formula

\overline{v}={\frac{\Delta x}{\Delta t}}

\overline{v} = average velocity

{\Delta x} = displacement

{\Delta t} = change in time
