How do you calculate velocity from force and distance?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
You cannot directly calculate velocity from only force and distance. However, if you also know mass, use the work-energy theorem:
v = √(2Fd/m)
where F is force, d is distance, and m is mass.
The physics behind it:
- Work done by force = F × d
- This work converts to kinetic energy = ½mv²
- Setting them equal: Fd = ½mv², then solve for v
