Under such conditions, all objects will fall with the same rate of acceleration, regardless of their mass. Objects that are said to be undergoing free fall, are not encountering a significant force of air resistance they are falling under the sole influence of gravity. a) will be applied to analyze the motion of objects that are falling under the sole influence of gravity (free fall) and under the dual influence of gravity and air resistance.Īs learned in an earlier unit, free fall is a special type of motion in which the only force acting upon an object is gravity.To answer the above questions, Newton's second law of motion (F net = m In situations in which there is air resistance, why do more massive objects fall faster than less massive objects?.Why do objects that encounter air resistance ultimately reach a terminal velocity?.In particular, two questions will be explored: In addition to an exploration of free fall, the motion of objects that encounter air resistance will also be analyzed. because the air resistance is the same for each? Why? These questions will be explored in this section of Lesson 3. But why do all objects free fall at the same rate of acceleration regardless of their mass? Is it because they all weigh the same?. This particular acceleration value is so important in physics that it has its own peculiar name - the acceleration of gravity - and its own peculiar symbol - g. In a previous unit, it was stated that all objects ( regardless of their mass) free fall with the same acceleration - 9.8 m/s/s.
