Question

How will the equations of motion for an object moving with uniform velocity change?

Answer 1

Equations of motion are :
v²=u² + 2as
v=u+at
s=ut + 1/2at²

According to the question, the velocity remains uniform.
This tells us that the acceleration is absent.

So the equations of motion will change as given below

1st Equation : 
v²=u² + 2as
v²=u² + 2(0)s  [Acceleration = 0]
v²=u²
Thus , v=u

2nd Equation :
v=u+at
v=u+(0)t
Thus, v=u

3rd Equation:
s=ut + 1/2at²
s=ut + 1/2(0)t²
Thus, s=ut
