Jealousy is a possibility; or could be their ex in the relationship.
The other object would be drawn more strongly to the one with increased mass. But whether that influenced their motion would depend on the actual forces involved. Since gravity is a "mutual" attraction, the effect on the two-object system could vary in ways other than the increased net attraction.
they wrote letters to each other. And they would talk to each other.
If two people on opposite sides are pushing on an object with equal force, the object will not move. The forces will cancel each other out, resulting in an equilibrium.
Increasing one object's mass would increase the gravitational force between the two objects. This would cause a greater attraction between the objects, resulting in an increase in the force pulling them towards each other.
When neither object is moving, the force between them is balanced. This is known as static equilibrium, where the forces acting on each object cancel each other out, resulting in no net force and no movement.
Yes they would.
The light comes out the other side. At the same time people all around the object are staring at it in amazement, nudging each other in the ribs, and exclaiming "Wow! Look at that! That object is transparent!"
Because they would hit each other and many people would die...
People would bump into each other and jostle each other, and hopefully laugh about it.
Collided Into would be with a stationary object while "with" would be with another moving object.
An object repels if it has the same type of charge (either positive or negative) as the other object it is interacting with. Like charges repel each other due to the electromagnetic force that pushes them away from each other.
No, because there is no such thing as being invisible. But if there was, the only way they would be aware of each other was if they bumped into each other. Which is kind of ironic. I like the idea.
