Newton realized that the mass that resists acceleration in the first law must be the same as the mass associated with gravity. Then when two bodies attract one another and accelerate toward each other, the two masses must be equally involved

woot! Gravitational locomotion in a non relativistic fashion!

Hey shellby are you a schitzo? Mabye jamie and you are the same person...

Smaller bodies -- those with less mass -- can still accelerate toward larger bodies. And for the smaller body it probably equates to the same thing, ultimately; it can run circles indefinitely or crash into the larger body. Either way, in this case, the smaller body my be fully involved with the larger being fairly indifferent.

f=ma, so when you have a larger mass, acceleration goes down for an equal force.

You have 19 newtons of force, 2 masses, one being 1kg and the other being 19kg, the 1k mass will accelerate at 19 meters per second per second, the other will accelerate at 1 meter per second per second.
