Question

30. Which one of the following statements is the best definition of uniform motion?
A. Motion in which the acceleration is zero, but the velocity changes.
B. Motion in which the object moves along a curved path with varying speed
C. Motion in which the velocity of the body increases at a constant rate.
D. Motion in which the object covers equal distances in equal intervals of time

Answer 1

D. Motion in which the object covers equal distances in equal intervals of time.

Explanation: Uniform motion means constant speed (and in rectilinear uniform motion, constant velocity), so equal distances are covered in equal time intervals.
