Newton's First Law

What does Newton’s First Law of Motion state?

• An object will always move in the direction of applied force.

• An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

• The force applied to an object is proportional to its acceleration.

• For every action, there is an equal and opposite reaction.

What happens to an object in motion if no external force is applied?

• It will stop immediately.

• It will gradually slow down and stop.

• It will continue moving at a constant velocity.

• It will move in a circular path.

Which of the following scenarios best demonstrates Newton’s First Law?

• A ball rolling on the ground eventually stops due to friction.

• A car accelerating when the gas pedal is pressed.

• A book remaining on a table until someone moves it.

• A rocket launching into space due to thrust.

If an object is at rest, what is the net force acting on it?

• Positive

• Negative

• Zero

• Depends on the object's mass

What is inertia?

• The force required to move an object.

• The resistance of an object to change its motion.

• The tendency of an object to accelerate.

• The force that stops an object from moving.
