Read Speed distance and displacement · Class 8 Q29
This SOF ISO pattern tests interpret motion. Read the condition carefully, then use the method below before you solve.
Motion and force questions become simpler when direction, starting condition, time and the acting forces are marked first.
Use the path and the clock together
Mark start, direction and time before reading the graph
Mark a start, direction and time interval first. On a graph, the slope tells how the quantity changes; on a path, distance and displacement may differ.
Find the tested idea
Write down the quantities, directions or conditions given in the stem before selecting a formula or rule.
Work from the evidence
Use one governing relationship at a time. For a visual question, trace the path; for a numerical question, keep units and signs consistent.
Verify before choosing
Use the wording, diagram and units exactly as given. Select an option only after it satisfies every stated condition.
OlympIQ exam lens
- ✓Extract the condition.
- ✓Apply one governing rule.
- ✓Check sign, unit or direction.
Check the result against a simple limiting case, diagram direction or unit before choosing an option.
