between the moon and the Earth a Spaceship travels. A person goes on a spacewalk and pushes the tractor trailer sized vehicle. Will the person be pushed back even though things in zero gravity have no mass?
If the person pushes on the tractor, then the tractor will push back on the person. That's Newton's 3rd law.Avgiu said:between the moon and the Earth a Spaceship travels.

No. The forces (due to Newton's third) are exactly equal. The accelerations are what are different.Intuitive said:If you pushed off of a tractor in space you would be pushed away from the tractor more than the tractor, You would experience most of the force of your push because the tractor has more mass, The more mass the tractor has the less force it will experience from your lesser mass and force of your push. Here's an analogy, Try jumping onto the Earth and make it move, you do not have enough force to make a big difference, The Earth is a body in space just like the tractor.
