Which of the following are true? As a ball falls freely in a vacuum, it falls the same distance each second. A ball is thrown straight up. At the top of its path, its velocity is zero. An object in freefall has different acceleration when it is going downward compared to when it is going upward. In freefall, an object’s velocity is proportional to the distance it has falls from rest – that is, an object that has fallen 10 m (from rest) is going twice as fast as when it had fallen only 5 m. A ball is thrown straight up. At the top of its path, its acceleration is zero.

A free falling object is an object that is falling under the sole influence of gravity. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. There are two important motion characteristics that are true of free-falling objects:Free-falling objects do not encounter air resistance. All free-falling objects (on Earth) accelerate downwards at a rate of 9.8 m/s/s (often approximated as 10 m/s/s for back-of-the-envelope calculations). Which of the following statements about free fall and the acceleration of gravity are TRUE? List all that apply. There are 5 correct selections. *
