how is the speed of a rolling ball effected by the following surfacees ? explain a) sand b) polish marble floor
Answers
Answer :
Your answer is below in the explanation.
Explanation: The speed of the rolling ball will be affected by the following surfaces because of friction. In the first case (a), the sand is a rough surface and so, the rolling ball has to face more friction for which it will gradually lose speed. In the second case (b), the polished marble floor is a smooth surface for which the rolling ball has to face less friction due to which, it will move for a longer time on the polished marble floor than on the sand.
Hope you understood and liked the answer.
Please mark as brainliest.
Answer:
send will exert more friction than polish marble floor. therefore the speed of ball decreases quickly but on marble floor due to very less friction the speed will decreases slowly.
