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.
