Newton's First Law of Motion Video Quiz

According to Newton's first law of motion, an object at rest will remain at rest unless acted upon by:

• External force

• Friction

• Gravity

• Acceleration

What is the force that resists motion called?

• Acceleration

• Friction

• Inertia

• Gravity

In which environment is there no friction and no wind resistance?

• Earth's atmosphere

• Underwater

• Space

• Desert

What is the capacity of an object to resist changes in motion called?

• Gravity

• Velocity

• Inertia

• Acceleration

What is the scalar value measured in kilograms that is proportional to an object's inertia?

• Mass

• Weight

• Volume

• Density

Which type of object has greater resistance to motion?

• Lightweight

• Hollow

• Massive

• Transparent

What is the sum of the vectors representing the forces operating on an object called?

• Tension force

• Applied force

• Frictional force

• Net force

If the net force on an object is not zero, there will be:

• Constant velocity

• No acceleration

• Some acceleration

• Negative acceleration

What does Newton's first law of motion tell us about an object in absence of a net force?

• It will stop

• It will accelerate

• It will preserve its state of motion

• It will change direction

What dictates that your body will tend to continue moving in a car accident?

• Gravity

• Inertia

• Friction

• Acceleration
