Document Summary
Physics 1501q - lecture 20 - center of mass and conservation of linear momentum. Key (in si units): t = time (s) x = distance (m) v = velocity (m/s) a = acceleration (m/s 2 ) = change in g = gravity = 9. 81 m/s 2. G = 6. 67 10 11 n m 2 /kg 2 m = mass (kg) Displacement of cm: r cm = ( m i r i ) / m. Velocity of cm: v cm = ( m i v i ) / m. Acceleration of cm: a cm = ( m i a i ) / m. If f net, external = 0, the cm won"t accelerate. The cm follows a path of projectile motion - this property allows us to track the paths of complex objects using prior knowledge ex.
