ooooooh angry bird!

how does cohesion/friction match gravity in equal proportion all the time? the centre of gravity of a large body e.g. earth, matches the centre of cohesive force of a smaller object e.g. a glass of water, provided there's motion but that's only the medium of observation of the forces.

1. a pseudo force acts on a body that is at relative motion or rest to another body if the body is disturbed.

- it is the force of friction/cohesion that exists between the two bodies. a sudden change in velocity does not correspond with an equal change in the dynamic cohesive force causing relative moment, known as the force of inertia.

2. a body reaches terminal velocity in motion against friction.

- any frictional force exactly equals the force of gravity?

anyone know what the hydrogen line is? i read some bohr and all i got was a reduced planck. atomic physics hit me!
