Question

A body experiences minimum friction in vacuuma

Answer 1

hey mate ur ans

yes it's true that particle experience minimum friction because there is no medium to accelerate it

Answer 2

Answer:

A body experiences minimum friction in a vacuum.

Explanation:

• A decaying atom actually encounters a force that resembles friction as it passes through the vacuum.
• True friction, however, would cause the atom to slow down, which is not what is being here.
• In reality, the moving atom loses momentum rather than velocity because it loses a small amount of mass during disintegration. To elaborate.
• The contact between the atom and the vacuum, despite the vacuum's emptiness and lack of forces on the atom, results in the excited atom's demise.
• A small quantity of energy equal to a particular amount of mass is lost as the moving atom decays to a lower energy state and emits photons as a result.

Thus, A body experiences minimum friction in a vacuum.
