Question

You will find it hard to drag a mat if?

Answer 1

Force of friction:

1. Friction is the force that opposes motion when the surface of one object comes into contact with the surface of another.

Dragging mat will be harder if:

1. If an object of heavy mass is placed on a mat then it will be difficult to drag it.
2. An increase of mass on the mat will increase the friction, as two surfaces are in contact with hardly pressed.
3. If the friction between mat and floor is increased then it would be hard to drag it.
4. If the irregularities of the floor or mat are increased.
