Laws of Motion Video Quiz

What does the law of inertia state about an object at rest?

• It will move if it has enough mass.

• It remains at rest unless acted upon by an outside force.

• It wants to start moving on its own.

• It naturally moves towards a state of motion.

What factor increases an object's inertia?

• Decreased volume

• Increased mass

• Increased speed

• Decreased mass

How does the mass of an object affect its inertia?

• Inertia decreases with increased mass

• More mass means more inertia

• Mass and inertia are not related

• Less mass means more inertia

According to Newton's second law, what does the acceleration of an object depend on?

• Its color and shape

• The force acting on it and its mass

• The object's position

• Its volume and density

What is the equation associated with Newton's second law of motion?

• Force = Mass / Acceleration

• Acceleration = Force + Mass

• Force = Mass x Acceleration

• Mass = Force x Acceleration

What demonstrates the effect of mass and acceleration in Newton's second law?

• A car moving on a highway

• A hammer breaking a piggy bank

• A book resting on a table

• A leaf falling from a tree

What happens when a jellyfish moves its body backward?

• It spins around.

• It moves forward.

• It stays in the same place.

• It moves backward.

What principle does a skateboard illustrate according to Newton's third law?

• For every action, there is a weaker reaction.

• Motion is not affected by external forces.

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

• Action and reaction are not related.
