Distance Travelled On an Interval
What is it?
Find velocity zeros, split the interval, and add absolute changes in position.
In simple words
- Find velocity zeros, split the interval, and add absolute changes in position.
- Worked pattern: For s=t^2-4t on [0,4], split at t=2; total distance is 8.
- Final check: domain, sign, notation, units, and reasonableness.
Important terms

Recommended for Class 12
Full school-level explanation
Find velocity zeros, split the interval, and add absolute changes in position.
CONCEPT AND RULE
Find velocity zeros, split the interval, and add absolute changes in position.
METHOD
For distance travelled on an interval, 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
For s=t^2-4t on [0,4], split at t=2; total distance is 8.
COMMON MISTAKE
Write the governing rule before substitution, keep brackets and signs visible, and check that the answer satisfies all domain or interval conditions.
