Answer:
Friction is caused by the inter locking of the irregularities in the two surfaces. When two surfaces are pressed harder together, the force of friction increases. Therefore, it is easy to drag a mat when no body is sitting on it rather than when a person is sitting on it.

it is easier to drag a mat on floor when nobody is sitting on it but much more difficult to drag the same when any person is sitting because the ground increases friction when a person sitting on the mat so it is difficult to move from one place to another ocabanga44 and 133 more users found this answer helpful 4.4 (65 votes)
