Free Fall ची गणना कशी करावी
Free Fall म्हणजे काय?
Free fall is the motion of an object falling solely under gravity, with no air resistance. Near Earth's surface, all objects accelerate at g = 9.81 m/s² regardless of mass — a fact Galileo demonstrated and Einstein explained through general relativity.
चरण-दर-चरण मार्गदर्शक
- 1Velocity at time t: v = g × t (starting from rest)
- 2Distance fallen: d = ½ × g × t²
- 3Time to fall distance d: t = √(2d / g)
- 4Velocity after falling height h: v = √(2gh)
Worked Examples

Object dropped from 45m
परिणाम
3.03 seconds · velocity 29.7 m/s (107 km/h)
t=√(2×45/9.81)=3.03s; v=9.81×3.03=29.7
