What keeps each planet in orbit around the Sun?
a balance of inertia and gravity
more gravity than inertia

Which of the following is an example of an unbalanced force?
For an object to change it's speed or direction, the forces must be:
Balanced
Unbalanced
Newton's _____ Law of motion states that every action has an equal and opposite reaction.
1st
2nd
3rd
4th
According to Newton’s Third Law, if someone jumps off a skateboard, the skateboard will roll backward because -
the mass of the skateboard is the same as the mass of the person jumping off.
the pull of gravity on the person is the same as on the skateboard, regardless of size.
the air resistance on the person is great and the friction on the skateboard is small.
for the force that sent the person forward, there is an equal force pushing back on the skateboard.
friction has no affect on speed
If an object is moving, what does it have to be doing to still be considered a balanced force?
moving at a constant speed
be unbalanced
stop moving
slow down
What force holds the planets in motion around the sun?
