Free Fall and Air Resistance Falling Bodies |
What makes it work? However, when the cup is in free fall, the water will not leak, making it seem as though the water is not experiencing the downward pull of gravity. It is merely falling to the ground at the same rate as its surroundings (the cup). This feeling of weightlessness (the sensation that you are not experiencing the downward pull of gravity) is also experienced by riders on free-fall rides. On the way to the top, the riders are pressed against their seats, which provides a sense of weight. But as they free fall, they fall at the same rate as their surroundings-in this case, their seats. Without the force of their surroundings pressing on them, the riders feel like they are weightless. But, in fact, they do have weight and are being acted upon by the force of gravity. |
