Hello
I hope you are absolutely fine. As per your mentioned query, speed is a scalar quantity which tells you how the object is moving fast. Whereas velocity is a vector quantity which tells you about the speed as well as direction.
I hope this helps you!
Revert for further query!
Hello Adarsh,
Speed is an example of a scalar quantity that indicates how fast an object is moving, without regard to direction. Speed only measures (i.e. magnitude) (e.g. 60 km/h).
Velocity is an example of a vector quantity that indicates how fast an object is moving, and direction - i.e. (e.g. 60 km/h north).
So speed tells you how fast, while velocity tells you how fast and, in what direction.
Difference between Speed and Velocity:
Speed is the rate at which an object moves, without considering direction. Velocity is the rate of motion in a specific direction.
Speed is a scalar quantity. Velocity is a vector quantity.
Question : If a body moves with a constant speed in a circle:
Option 1: no work is done on it
Option 2: no force acts on it
Option 3: no acceleration is produced
Option 4: its velocity remains constant
Question : In 1851, who founded the science of hydrodynamics with his law of viscosity describing the velocity of a small sphere through a viscous fluid?
Option 1: Daniel Bernoulli
Option 2: George Gabriel Stokes
Option 3: Evangelista Torricelli
Option 4: Heinrich Gustav Magnus
