Question

a vacuum has no air. how do you think the results will change if the object fall through a vacuum

Answer 1

if an object falls through vacuum it will reach the ground at the same time with another object taken for comparison

Answer 2

Answer:

The object will continue to move with same velocity.

Explanation:

• When an item is subjected to a net external force that is not zero, that is, when the total of the forces acting on the object is not zero, it experiences acceleration.
• On Earth or any other planet, when anything is dropped, it has no initial velocity.
• However, the force of gravity is exerting a net downward pull on the item. In that instance, the item is speeding, as the response indicates.
• Imagine a scenario where an item is given a downward beginning velocity in a vacuum.
• Since there is no net force acting on the item in this situation, it will keep moving downhill at its initial speed without accelerating.

Hence as a conclusion we can state that as per the newton law of inertia, The object will keep moving at the same speed and with same direction.
