Distinguish between speed and velocity.for class 9
Answers
Answer:
Speed is how fast an object is moving, while velocity is the rate at which an object changes position in a certain direction. Speed is calculated by the displacement of space per a unit of time. Velocity is calculated by the displacement of space per a unit of time in a certain direction. In short, velocity factors in direction, but speed does not.
The short answer is that velocity is the speed with a direction, while speed does not have a direction.
Speed is a scalar quantity—it is the magnitude of the velocity. Speed is measured in units of distance divided by time (e.g., miles per hour, feet per second, meters per second, etc.).
Velocity is a vector quantity—when giving the velocity we must specify the magnitude (the speed) and the direction of travel. For example you might drive 100km/hr (the speed) in a northerly direction.
