Question

Explain the transformation of energy in the following case:
1)A stone dropped from the roof of a building.
2) A ball thrown upwards from. ​

Answer 1

Answer:

1)A stone dropped from the roof of a building.

• A stone dropped from the roof of a building has potential energy at the starting .

• When it is dropped then the potential energy gets converted to kinetic energy .

• During this its total mechanical energy remains the same .

Answer 2

Answer:

hope it helps

Explanation:

i)When a ball is thrown upwards, its kinetic energy at the thrower's hand is transformed into potential energy at the maximum height. ..

(ii) When a stone is dropped from a height its potential energy at the height is transformed into kinetic energy on reaching the groud
