Newton's Laws of Motion - HW

What does Newton's First Law state about an object at rest?

• It will change its state of motion randomly.

• It will move in a circular path.

• It will remain at rest unless acted upon by an external force.

• It will start moving on its own.

Why does a ball eventually stop when thrown?

• Because it is not heavy enough.

• Because it loses energy.

• Because of wind resistance and friction.

• Because of the force of gravity.

How is inertia related to mass?

• Inertia is inversely proportional to mass.

• Inertia is equal to mass.

• Inertia is not related to mass.

• Inertia is directly proportional to mass.

What is inertia?

• The force that moves an object.

• The resistance of an object to changes in its state of motion.

• The speed of an object.

• The weight of an object.

What does Newton's First Law tell us about an object with zero net force acting on it?

• It will stop moving.

• It will accelerate.

• It will change its direction.

• It will preserve its state of motion.
