​

Answer 1

Answer:

decreased

Explanation:

a glass normally slips from our hand if we do not hold it properly this is because the absence of friction or because of less friction. due to friction we sometimes fall, slip, get tired easily but on the flip side if friction is reduced to a greater extent then it will be almost impossible for us to walk.
