Question 7 - Filling Gaps for Uniform Motion - Questions at the end of the chapter - Chapter 8 Class 7 - Measurement of Time and Motion (Curiosity)

Last updated at May 4, 2026 by

Question. Data for an object covering distances in different intervals of time are given. If the object is in uniform motion, fill in the gaps in the table.

Given table:

Time (s) 0 10 20 30 ? 50 ? 70
Distance (m) 0 8 ? 24 32 40 ? 56
📚 Concept: Comparing Uniform and Non-uniform Motion

Answer.

  • From 0 to 10 s, distance covered = 8 m.
  • So in uniform motion, 8 m is covered every 10 s.

Filling the gaps:

  • At 20 s
    Distance = 16 m
  • Time when distance = 32 m
    Time = 40 s
  • At 60 s
    Distance = 48 m

The completed table:

Time (s) 0 10 20 30 40 50 60 70
Distance (m) 0 8 16 24 32 40 48 56
