Velocity is only displacement
|

velocity has direction
|
Detailed explanation-1: -Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.
Detailed explanation-2: -Note that speed has no direction (it is a scalar) and the velocity at any instant is simply the speed value with a direction.
Detailed explanation-3: -Speed tells you only how fast or slow an object is moving. It doesn’t tell you the direction the object is moving. The measure of both speed and direction is called velocity. Velocity is a vector. A vector is measurement that includes both size and direction.
Detailed explanation-4: -Answer. Speed is defined as the distance travelled by a body in a given interval of time. Velocity is defined as the displacement of a body in a given interval of time. It is a scalar quantity.
