You and your brother are moving a couch for your mom. You move the couch at 65 N Right and your brother moves the couch at 60 N Right. Is the net force balanced or unbalanced?

Unbalanced

400
True or False. If objects move farther apart their gravitational force is decreased.
True. (For example, the sun is so far away from us that it doesn't affect us as much as the gravitational pull of the Earth.)

You are having a tug of war with your puppy. You are pulling the rope with a force of 37 N Right and your puppy is pulling the rope at 37 N Left. Is it balanced or unbalanced?

Balanced

500
Why are we affected by the gravitational force of the Earth and not the gravitational force of a pencil?
We are affected by the gravitational force of the Earth because it is so large. Even though the pencil has gravitational force, it is too small to affect us.

What are 2 ways unbalanced force can change the motion of an object?

1.) when unbalanced forces act on an object at rest, the object will move.

2.) when unbalanced forces act on a moving object, the motion of that object will change.
