Newton's Three Laws

[whitehorsey]

1. Which of these are possible wording of Newton's Three Laws? Pick which ones are correct.

Objects always fall.
An object in motion always stays in motion unless acted upon by a force.
When two objects interact, they experience equal and opposite forces.
What goes up, must come down.
An object in motion only stays in motion if acted on by a force.


3. I think it would be just these:
An object in motion always stays in motion unless acted upon by a force. (1st)
When two objects interact, they experience equal and opposite forces. (3rd)
