Question

If there is no change in speed but change in direction then how delta v changes in m/s​

Answer 1

Explanation:

if there is a change of direction in velocity, then it must have changing velocity becouse velocity depends on direction also

then there must be acceleration

but this change can't be seen in m/s

and measure in magnitude becouse

magnitude and direction is two different cases

Answer 2

differentiation is the cahnge of a function with respect to the change of the variable so it says that if there is a small change in variable the function will also have a small change.
