Questions and Answers

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

  • The acceleration of an object is directly proportional to the magnitude of the net force applied in the same direction as the force. (correct)
  • The acceleration of an object is directly proportional to the square of the magnitude of the net force applied.
  • The acceleration of an object is inversely proportional to the magnitude of the net force applied.
  • The acceleration of an object is inversely proportional to the square of the magnitude of the net force applied.
  • What is the mathematical expression of Newton's Second Law of Motion?

  • F = a / m
  • F = m / a
  • F = ma (correct)
  • F = m - a
  • What is the effect of increasing the mass of an object on its acceleration, according to Newton's Second Law of Motion?

  • The acceleration of the object remains the same.
  • The acceleration of the object becomes zero.
  • The acceleration of the object decreases. (correct)

    Study Notes

    Newton's Second Law of Motion

    • Newton's Second Law of Motion describes the relationship between the force acting on a body and the resulting acceleration.
    • The force acting on an object is equal to the product of its mass and acceleration.
    • Mathematically, Newton's Second Law is expressed as F = ma, where F is the force, m is the object's mass, and a is the acceleration produced.
    • The acceleration of an object is directly proportional to the magnitude of the net force applied in the same direction as the force.
    • The acceleration of an object is inversely proportional to the object's mass.
