Question

What force(s) were acting on the objects dropped in the air (normal mode)? What force(s) was acting on the objects dropped in the vacuum?

A) Only gravitational force in both cases.

B) Gravitational force and air resistance in the air, only gravitational force in the vacuum.

C) Only air resistance in the air, only gravitational force in the vacuum.

D) Only air resistance in both cases.

Answer 1

When objects are dropped in the air (normal mode), the forces acting on them are the gravitational force and air resistance. On the other hand, when objects are dropped in a vacuum, only the gravitational force is acting.

Step-by-step explanation:

Answer:

When objects are dropped in the air (normal mode), the forces acting on them are the gravitational force and air resistance. The gravitational force pulls the object towards the ground, while air resistance opposes the motion of the object through the air. The magnitude of the air resistance depends on the size and shape of the object.

On the other hand, when objects are dropped in a vacuum, only the gravitational force is acting. In the absence of air, there is no air resistance to slow down the object's motion, allowing it to fall with only the force of gravity.

Therefore, the correct answer is B) Gravitational force and air resistance in the air, only gravitational force in the vacuum.
