MCQ
When the distance covered by an object is directly proportional to the time interval, it is said to travel with:
  • ✓
    Constant speed
  • B
    Zero velocity
  • C
    Constant acceleration
  • D
    Uniform velocity
✓

Answer

Correct option: A.
Constant speed
When distance is proportional to time, the ratio of distance and time remains constant.
This means that in equal time intervals, the particle is travelling equal distances.
So clearly the speed of the particle remains constant.
