Why is speed and velocity almost the same?

Answer 1

Because that's just how it is.

speed = distance/time (yes)

velocity= distance/time(no)

both are measured in m/s, km/hr or mph (no)

velocity is a synonym of speed. (no)

All of the above is true. However, in physics, you usually would convert the km/hr or mph to m/s. In physics, we typically use SI units. The only subtle difference between speed and velocity is that velocity has a direction.(YES)

ex: My speed is 24 m/s however my velocity is 24 m/s going north.

Hope this explained it a little more.

Speed tells how fast something is travelling; for example if a car travels 90 miles in 2 hours its speed is 45mph (miles in each hour). And this could be about a car which is travelling around curves and changing direction at junctions.

But "velocity" tells not just the speed but also the direction of travel; for example the aeroplane is flying at 350 kilometres per hour (its speed) in a northerly direction (its direction); it does not change direction until it acquires a new "velocity".
