Compare speed and velocity?
Answers
Answer: Speed & Velocity
We often find the terms speed and the velocity as similar; however, practically, there’s a difference between them in them in terms of nature.
Let’s suppose I traveled 120 km in 5 hr, so obviously my speed will be distance/time, i.e., 120/5 or 24 kmph. So this was the case for the speed, now if I ask which directions I took in my journey and from starting, in the middle or while making turns and till the end, was my speed the same? The answer will be clearly No; it’s because initially the speed was 0 when my car was at rest, when I started, it was slow, I also increased my speed, also decreased during the turns; on the whole, my speed wasn’t the same, which means I traveled with a velocity (varying speed) to cover 120 km distance in 5 hrs. Now. let’s discuss the difference between speed and velocity in tabular form:
Speed
Velocity
Speed is simply the rate of change of motion.
Velocity is direction-aware and it is the rate of change of position of an object.
Speed is the distance traveled by a body in a unit time.
Velocity is the displacement covered by a body in a unit time.
Speed is a scalar quantity
Velocity is a vector quantity.
Speed ascertains how fast a body moves.
Velocity ascertains the object’s speed and the direction it takes while moving.
SPEED is the rate at which someone or something moves or operates or is able to move whereas velocity is the speed of something in a given direction.
