These are true/false statements, except for the last question, which is multiple choice.
If a statement refers to “two bodies” interacting via some force, you are not to assume that these two bodies have the same mass.
Every force has one and only one 3rd law pair force.
false because you can't have one force by itself
The two forces in each pair act in opposite directions.
true
The two forces in each pair can act on the same body or on different bodies
true
The two forces in each pair may have different physical origins (for instance, one of the forces could due to gravity, and its pair force could be a normal contact force).
true
The two forces of a 3rd law pair always act on different bodies.
i thought this was false but i was told that this is true. can someone explain it to me please?
Given that two bodies interact via some force, the accelerations of these two bodies have the same magnitude but opposite direction. (Assume no other forces act on either body.)
false
According to Newton's 3rd law, the force on the (smaller) moon due to the (larger) Earth is
greater in magnitude and antiparallel to the force on the Earth due to the moon.
greater in magnitude and parallel to the force on the Earth due to the moon.
equal in magnitude but antiparallel to the force on the Earth due to the moon.
equal in magnitude and parallel to the force on the Earth due to the moon.
smaller in magnitude and antiparallel to the force on the Earth due to the moon.
smaller in magnitude and parallel to the force on the Earth due to the moon.
again, I'm very confused with the third law..
