Play an AI-generated podcast conversation about this lesson

What is the relationship between the acceleration of a body and the force causing it according to Newton's Second Law of Motion?

Acceleration is inversely proportional to the force causing it

Acceleration is directly proportional to the force causing it (correct)

Acceleration is independent of the force causing it

Acceleration is proportional to the square of the force causing it
