Difference Between The Speed And Velocity

Difference Between The Speed And Velocity

Speed:

  • The speed is nothing but the rate of change of distance covered by an object per unit of time. In other words, speed is the rate of time at which an object is moving along a path. In order to explain the speed there is no need to consider the direction of the motion of an object. That’s why speed is a scalar quantiy . it is only ha magnitude but no direction.
  • The speed is the rate of change of distance per unit time. It defines how fast an object is moving. The S.I unit of the speed is m/s. the speed can never be zero. The dimension of speed is LT-1 . the formula for speed in speed =distance/time.

Speed And Velocity

Velocity:

  • Velocity is noting but the rate of change of displacement covered by an object per unit time. In other words, velocity is the rate of change of time as well as the direction of the moving object. In order to define velocity we need to consider the direction of the motion of an object. That’s why velocity is a vector quantity. The velocity has both the magnitude as well as direction.
  • Velocity defines how fast an object is moving but in which direction. It is vector quantity. Velocity defines the rate of change of motion as well as the position of an object. The S.I unit of velocity is m/s. velocity can be positive , negative or even zero . the dimension of velocity is LT-1. The formula for velocity is velocity = displacement/time.
