1. The second law of motion states that force is equal to the mass of an object multiplied by its acceleration (F = ma). This means an object's acceleration is directly proportional to the net force acting on it and inversely proportional to its mass.

  2. The direction of motion of falling objects does not change; they accelerate downward due to gravity. If unaffected by other forces, they continue to fall straight down until they encounter resistance or impact.

  3. Yes, the velocity of objects in free fall changes continuously; they accelerate downward due to gravity, increasing their velocity by approximately 9.8 m/s² each second, assuming no air resistance.

  4. The mass of an object is a measure of its matter content, reflecting its resistance to acceleration and inertia, independent of its location or the gravitational force.

  5. The gravitational force with which the Earth attracts an object depends on two factors: the mass of the object and the distance between the object's center and the Earth's center.
