Question

When a pencil cell is released from a certain point on an inclined wooden board, it travels a
distance of 35 cm on floor A before it comes to rest. When the same pencil cell is released
from the same point on the same inclined board, it travels a distance of 20 cm on floor B
before coming to rest. Which floor, A or B, offers greater friction? Give reason for your
answer.​

Answer 1

Answer:

We know that friction reduces the acceleration or speed of motion of any object, as we saw in the first experiment with floor A the cell traveled for 35 cm whereas in experiment 2 the cell traveled for 20 cm which means that floor B offers more friction,thus stops the cell in lesser travel.

Answer 2

Answer:

Answer. We know that friction reduces the acceleration or speed of motion of any object, as we saw in the first experiment with floor A the cell traveled for 35 cm whereas in experiment 2 the cell traveled for 20 cm which means that floor B offers more friction,thus stops the cell in lesser travel.
