When you drop objects like a foam ball, a soccer ball, and a bowling ball from the same height on Earth, they will all fall under the influence of gravity, accelerating downwards at approximately 9.81 m/s², regardless of their mass. This is a consequence of the equivalence principle, which states that the effects of gravity are the same for all objects in free fall, as long as air resistance is negligible.
However, in practical scenarios on Earth, air resistance plays a role, especially for objects with significantly different shapes and sizes. Here’s a brief overview of what you might observe:
1. **Foam Ball:** The foam ball is light and has a larger surface area relative to its mass. As a result, it would experience more air resistance compared to the other balls. It may float or drift down slowly, depending on its size and the density of the foam.
2. **Soccer Ball:** The soccer ball is heavier than the foam ball and has a standard size and shape that allows it to cut through the air more effectively. It would fall more quickly than the foam ball but may still be affected by air resistance, causing it to take longer to reach the ground compared to a denser object.
3. **Bowling Ball:** The bowling ball is heavy and has a smooth shape. It would experience less relative air resistance compared to the foam ball and would fall to the ground the fastest of the three.
In summary, if you were to conduct this experiment, you would likely observe that the foam ball takes the longest to hit the ground due to air resistance, while the bowling ball hits the ground first. The soccer ball would fall in between the two. If you were in a vacuum (where there is no air resistance), all three balls would hit the ground at the same time.
