Question

Give scientific reason
1)accelaration has time factor twice
2)displacement is independent of its path

Answer 1

Now the ball is under the influence of gravity, which, on the surface of the Earth, causes all free-falling objects to undergo a vertical acceleration of –9.8 m/s2. This acceleration is negative because its direction is vertically downward.

Answer 2

Answer:

Presently the ball is affected by gravity, which, on the outside of the Earth, causes all free-falling articles to experience a vertical increasing speed of – 9.8 m/s2.

This speeding up is negative since its heading is vertically descending.

Change in speed is straightforwardly corresponding to time when increasing speed is consistent.

On the off chance that speed increments by a specific sum in a specific time, it should increment by twice that sum in double the time.
