What is vector and scaler quantity ?
Vector quantities refer to the physical quantities characterized by the presence of both magnitude as well as direction.
A scalar quantity is defined as the physical quantity with only magnitude and no direction
speed
- It is a scaler quantity , do not have direction
- speed can be calculated by the formula = distance / time or distance per unit time
- unit of speed is km/h , 400 km/h
velocity
- It is a vector quantity , have magnitude as well as direction
- Velocity can be calculated by the formula = displacement / time or displacement per time
- 20 m/s south , here magnitude of velocity is 20m/s and the direction is south
