Explanation:

  1. Mass is a fundamental property of matter that does not change due to the application of force.
  2. The mass of an object is a measure of the amount of matter it contains and is unaffected by the forces acting on it.
  3. For example, even if a car accelerates or changes direction, its mass remains constant. The only time mass would change is if there is a physical transformation of the substance (like burning fuel, which reduces the mass of the fuel).

 Additional Information

A force is any interaction that, when unopposed, will change the motion of an object. It can cause objects to start moving, stop moving, or change direction.

Forces have both magnitude and direction, making them vector quantities. The effects of force on a body depend on:

  1. The type of force: Whether it is gravitational, normal, frictional, tension, or applied force.

  2. The magnitude of the force: A greater force generally causes a larger effect.

  3. The point of application: The place where the force is applied can affect how the object moves (e.g., pushing from the center or edge of an object).

  4. The mass of the object: According to Newton's second law, a more massive object requires a greater force to produce the same acceleration.
