Position, Displacement, and Distance
What is it?
Position s(t) is signed location; displacement is change in position; distance is total path length.
In simple words
- Position s(t) is signed location; displacement is change in position; distance is total path length.
- Worked pattern: From s=2 to s=-3, displacement=-5 while distance for direct travel is 5.
- Final check: domain, sign, notation, units, and reasonableness.
Important terms
Position, displacement, and distance: Position s(t) is signed location; displacement is change in position; distance is total path length.
What you should learn
- State the rule for position, displacement, and distance.
- Solve a position, displacement, and distance problem step by step.
- Check the result, restrictions, notation, and units.
Recommended for Class 12
Full school-level explanation
Position s(t) is signed location; displacement is change in position; distance is total path length.
CONCEPT AND RULE
Position s(t) is signed location; displacement is change in position; distance is total path length.
METHOD
For position, displacement, and distance, identify the given information and required result. Select the matching definition or formula, state its conditions, substitute carefully, simplify one line at a time, and check.
WORKED EXAMPLE
From s=2 to s=-3, displacement=-5 while distance for direct travel is 5.
COMMON MISTAKE
Write the governing rule before substitution, keep brackets and signs visible, and check that the answer satisfies all domain or interval conditions.
How to solve position, displacement, and distance
How it works
- Identify the mathematical objects, givens, restrictions, and required result.
- Choose and write the relevant definition, theorem, or formula.
- Substitute with brackets and carry out one justified step per line.
- Simplify, state the final answer clearly, and verify it in the original setting.
Remember
- Position, displacement, and distance
- rule
- worked example
- worked example
How the ideas connect
Worked example: From s=2 to s=-3, displacement=-5 while distance for direct travel is 5.
Deeper understanding
Go beyond memorising Position, Displacement, and Distance. Connect the definition to reasons, relationships, exceptions, and exam wording.
