Question

A ball was thrown to a height of 10 m vertically upwards. The acceleration of the ball while coming down was - 9.8 m/s2 . What was the acceleration of the ball while it was going up?

Answer 1

On a free falling object with no external forces on the object, it's acceleration is always equal to gravity on the planet.

Since gravity is always in downward direction, So whether ball is going upward or downward, acceleration on it will be always equal to -9.8 m/sec^2.

So while ball is going up, acceleration = -9.8 m/sec^2 (-ve sign represents that acceleration is in downward direction)

Let me know if you've any query.
