Motion Laws

What is inertia?

• Inertia is the energy stored in an object.

• Inertia is the force that causes objects to move.

• Inertia is the resistance of an object to changes in its state of motion.

• Inertia is the ability of an object to float in water.

According to Newton's First Law, an object at rest tends to stay at rest unless...

• acted upon by an external force

• accelerated by gravity

• subjected to friction

• in motion at a constant speed

What is the other name for Newton's First Law?

• Law of Inertia

• Law of Rest

• Newton's Third Law

• Principle of Equilibrium

Inertia is the resistance of an object to change its...

• color perception

• motion or state of rest

• ability to float

• resistance to acceleration

True or False: Newton's First Law states that an object in motion tends to stay in motion unless acted upon by an external force.

• True

• Sometimes

• Maybe

• False

What is the relationship between mass and inertia?

• Mass and inertia are inversely proportional.

• Mass and inertia are directly proportional.

• Mass has no effect on inertia.

• Inertia is not related to mass.

What is the main concept behind Newton's First Law?

• Inertia

• Friction

• Acceleration

• Gravity

What is the role of friction in relation to Newton's First Law?

• Friction always slows down an object's motion

• Friction acts as the force that counteracts an object's tendency to remain in its state of motion or rest.

• Friction causes objects to accelerate without any external force

• Friction has no effect on an object's motion

How does inertia affect the motion of objects?

• Inertia causes objects to speed up

• Inertia makes objects change direction easily

• Inertia affects the motion of objects by making them resist changes in their state of motion.

• Inertia has no effect on the motion of objects

Explain how Newton's First Law of Motion applies to a passenger in a car that suddenly stops.

• The passenger will move forward due to inertia.

• The passenger will remain at rest.

• The passenger will move backward.

• The passenger will stay in the same position.
