Are there any forces acting on the apple? After a gust of wind has blown through a tree, an apple falls to the ground.

Question

BlackTom AI · Accepted Answer

The question asks us to evaluate whether there are forces acting on the apple after a gust of wind has blown through a tree and the apple falls to the ground.
Option 1: True. In this situation, several forces act on the apple. Gravity pulls the apple downward toward the Earth's center. As the apple moves through the air, air resistance (a type of drag) acts opposite to its motion, opposing the downward movement. Depending on the wind and the apple's motion, there can also be a buoyant force from the surrounding air, though this is usually small compared to gravity. If the gust gives the apple a horizontal velocity, the air exerts a drag force in the opposite direction of that motion as well. All of these are real forces acting on the apple during its fall.
Option 2: False. This would claim that no forces act on the apple, which contradicts basic physics. Even in free fall, gravity acts on the apple, and any motion through air introduces drag. The presence of wind and air means there are additional forces beyond gravity, making this option incorrect.
In summary, considering gravity and aerodynamic effects as the apple falls through the air after being disturbed by a gust, the claim that there are forces acting on the apple is correct, while the claim that there are no forces is incorrect.
