How do you find velocity without knowing time?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Use formulas that don't include time:
- v² = u² + 2as (when you know acceleration and distance)
- v = √(2gh) (for free fall from height)
- v = √(2KE/m) (from kinetic energy)
- v = p/m (from momentum)
Note: These energy and momentum approaches are particularly useful in collision problems where time is unknown or irrelevant.
