Solution
The correct options are
A It covers equal distances in equal interval of time.
D Acceleration is zero.
When an object is moving with uniform velocity, the motion is known as uniform motion. This means is covers equal distances in equal interval of time. Also for an object whose velocity is constant, acceleration is zero. This can be seen from the first equation of motion as well.
v=u+at. Since velocity is constant, v=u
or, 0=at→ a=0
