Understanding Newton's Laws of Motion Questions

What is Newton's First Law of Motion also known as?

• The Law of Inertia

• The Law of Action and Reaction

• The Law of Acceleration

• The Law of Gravity

According to Newton's First Law, what happens to an object at rest?

• It will accelerate

• It will stay at rest unless acted upon by an unbalanced force

• It will start moving on its own

• It will change direction

Which of the following best describes inertia?

• The force that causes objects to move

• The tendency of objects to change their motion

• The tendency of objects to resist changes in their motion

• The ability of objects to accelerate

What is the mathematical equation for Newton's Second Law of Motion?

• F=ma

• a=m/F

• E=mc^2

• F=mg

In Newton's Second Law, what does 'a' represent?

• Velocity

• Force

• Mass

• Acceleration

How does mass affect acceleration according to Newton's Second Law?

• Mass and acceleration are unrelated

• More mass means more acceleration

• More mass means less acceleration

• Mass does not affect acceleration

What is the main idea of Newton's Third Law of Motion?

• Inertia is related to mass

• Acceleration is proportional to force

• Objects in motion stay in motion

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

Which of the following is an example of Newton's Third Law?

• A rocket launching into space

• A book resting on a table

• A car accelerating on a highway

• A ball rolling down a hill

Why are Newton's Laws important in science?

• They help predict how objects will move

• They are used to calculate energy

• They explain the behavior of light

• They describe chemical reactions

Which of the following situations would require the use of theories other than Newton's Laws?

• An electron moving in an atom

• A planet orbiting the sun

• A ball being thrown

• A car driving on a road
