Which of the following statements is true?

The more massive an object, the faster its acceleration of gravity.

Heavier objects will free-fall more quickly than lighter objects.

Objects in free-fall do not experience air resistance.

Mass and weight are the same.

The true statement is - the more massive an object, the faster its acceleration of gravity

If the object is massive then the acceleration of gravity is faster, such objects will free fall more quickly than lighter objects. The objects in free fall do not experience air resistance are all true statements because the force of gravity which depends upon weight.

It is directly proportional to the weight. Yet the mass and weight are not same because mass is only value in kilograms but the weight is the value in which mass and gravitational acceleration are included. However, its unit is kilograms - 2 which is equal to Newton law of formula which is also unit of force.
