Question

How will the equations of motion for an object moving with a uniform velocitychange?

Answer 1

For an object moving with uniform velocity, the acceleratio would be equal to 0.  Hence, in laws of motion, you can substitute a = 0 and they will becomeLaw1 : v = u Law 2 : s = utLaw 3: v^2 = u^2 i.e. v = u again.
