What formula is v² = u² + 2as?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
This is the third equation of motion, connecting velocity and displacement without involving time. It's particularly useful when you know initial velocity (u), acceleration (a), and displacement (s), but need to find final velocity (v) or vice versa. For instance, if you drop a ball from rest (u=0) with gravity a=10 m/s² over a distance s=5m, the final velocity is v = √(0 + 2×10×5) = 10 m/s.
