Answer:
speed
the distance Traveller one unit Time is called spped.
velocity
the Traveller equal distance equal interval of time is called velocity.
speed :
speed of an object is defined as the rate of change of position of the object in any direction.
speed = distance traveled/ time taken
⏩it's is a scalar quantity
⏩ it can be zero or positive but never be negative.
⏩si unit = m/ sec.
velocity:
the rate of change of displacement of a particle with time is called the velocity of the particle.
velocity = displacement/ time taken
⏩ it is a vector quantity
⏩ the velocity of an object can be positive zero and negative.
⏩si unit = m/ s.
