Answer 2

Answer:

The incorrect statement is

III. There is danger of slipping while walking on ice since there is more friction

Explanation:

I. Frictional force helps us to walk without slipping

This statement is true as friction tends to stop relative motion between our feet and the floor thus, providing a grip

II. The friction between our feet and the ground holds our feet to the ground

This statement is also true (refer to explanation I.)

III. There is danger of slipping while walking on ice since there is more friction

This statement is false as there is danger of slipping while walking on ice since there is less friction

IV. Friction causes damage to the soles of our shoes

This statement is true since friction is responsible for wear and tear which causes damage to the soles of our shoes
