Newton's 1st Law is also called the Law of ...
Friction
Inertia
Unbalanced forces
Newtons
A space probe that has run out of fuel in remote outer space (where there is no friction and no other planets or stars) continues moving
because some kind of force acts on it.
in a curved path.
even though no force acts on it, due to inertia
due to gravity.

What does Newton's First Law of Motion state?
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass.
For every action, there is an equal and opposite reaction.
The force of gravity acting on an object is directly proportional to its mass.
A car is driving at a constant velocity of 75 m/s on the highway headed to Tucson, on a windy day. What is the force acting upon it to continue it's state of motion?
0 N, due to "the constant velocity" which means the car is already moving. It does not need force to continue it's state of motion.
Really? This question again? Obviously it is 75 m/s because of one of Newton's Laws.
Wait, I do know, I just don't know how to explain it. But, It is one of the laws... right?
75 N to the right, due to action and reaction, as well as inertia.
The girl on the sled will remain in motion unless
her motion is changed by magnetic forces.
she is stopped by an outside force.
she accelerates at a constant speed.
the force of friction forcer her to move faster.
What does it mean when forces are balanced?
The object is accelerating.
The object is moving at a constant velocity.
The object is at rest.
Both B and C are correct.
Newton's Second Law of Motion can be mathematically expressed as:
F=ma
a=mF
Both A and B
None of the above
What is the effect of mass on inertia?
More mass means less inertia.
Mass has no effect on inertia.
More mass means more inertia.
Only shape, not mass, affects inertia.
