Gravity and Other Forces

Newton said that any two masses will...

• combine into a larger mass.

• attract each other.

• create gravitational fields.

• push each other apart.

In this force diagram, which arrow is representing Friction?

• A

• B

• C

• D

How do you know if this object is balanced?

• It's not balanced; it's Net Force is 14 N

• It is balanced because its Net Force is 0 N.

• It's not balanced; it's Net Force is 10 N left and 4 N up.

• I don't know how to tell.
