Newton's Second Law of Motion (Force and Acceleration)

What does Newton's Second Law of Motion state?

• A) Force equals mass times acceleration (�=��F=ma)

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

• C) Objects at rest stay at rest unless acted upon by an external force

• D) Energy cannot be created or destroyed

Which of these is a practical example of Newton's Second Law?

• B) Pushing a heavier shopping cart requires more effort

• C) A rocket launching into space

• D) Water boiling in a pot

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

• A) More mass means more acceleration

• B) Mass does not affect acceleration

• C) Less mass leads to more acceleration

• D) Mass inversely affects acceleration

What happens to the acceleration of an object if the force applied to it is doubled?

• A) The acceleration is halved

• B) The acceleration remains the same

• C) The acceleration is doubled
