Motion in Curved Space-time
Newton’s Description
- Held ball does not move Dropped ball has accel. a = g
- Einstein’s Description: No “force of gravity”
- Held ball does not move Dropped ball has accel. a = g Force of hand balances Inertial motion in curved the curvature of space-time space-time near earth
f = ma a = f/m f = fgravity
