what is speed and velocity
Answers
Explanation:
In conclusion, speed and velocity are kinematic quantities that have distinctly different definitions. Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... Velocity is the rate at which the position changes.
SPEED:
Speed is a scalar quantity.
It shows, " how fast is an object moving?".
It is the rate at which the distance covered by the object is noted.
Speed is zero when object does not show any movement.
Formula .... Speed = distance / time
VELOCITY:
Velocity is a vector quantity.
It shows, "the rate at which the object moves it's position".
Velocity is zero when the object reaches it's original position again as it is the rate of change in object's position.
Formula..... Velocity = displacement / time
