Thread: physics question?

An airbag inflates when a collision occurs, which protects the passenger inside. Why does the airbag soften the blow. Discuss the physics involved in this...
I think its because the air bag slows down the persons acceleration..?

[mass(velocity) before collsion] equals [mass(velocity) after collision]
m1v1 + m2v2 = m1v1' + m2v2'
velocity is a vector, change the sign on either force to represent direction cause they are comiing at eachother.

how bout this one..
why does an astronaut in a spacecraft orbiting Earth experience a feeling of weightlessness?
maybe cause the radius is larger?
