Fall of parachute towards the earth surface is not a free fall why?
Answers
Explanation:
No, the falling of Parachute on the earth's surface is not free fall because it has larger surface area due to which it offers the larger air resistance which decreases the acceleration of the parachute so, the parachute will fall towards the earth's surface approximately with constant velocity.
Please if helpful mark as brainliest answer
The fall of a parachute towards the earth's surface is not a free fall because of the large air resistance acting on it.
- We call a body freely falling if only gravity is acting upon it.
- Each and every falling body experiences air resistance but it is very very small that it is best to be neglected.
- Similarly when a parachute falls towards the earth's surface, it also experiences air resistance.
- But this air resistance is quite large owing to parachute's large surface area and hence it cannot be neglected.
- This air resistance acts against gravity.
- Hence, we do not consider the fall of a parachute towards the earth's surface as a free fall.
