In Newton's Second Law of Motion, what is the relationship between acceleration and the net force acting on a body?
In Newton's Second Law of Motion, what is the relationship between acceleration and the net force acting on a body?
- Acceleration is directly proportional to the net force. (correct)
- Acceleration is inversely proportional to the net force.
- Acceleration is proportional to the square of the net force.
- Acceleration is unrelated to the net force.
