List 3 examples in which friction us or makes things easier in our daily life. explain the effect of friction for each.

Friction can help us play tennis, knock down bowling pins, and cook dinner.

The three examples in which friction helps us or makes things easier in our daily life are :

(a) Friction helps us to walk. if there were no friction, we wouldn't be able to push earth backwards by our feet . Thus we will not get the reaction force from earth which is necessary for walking.

(b) Conveyor belts will not work if there is no friction. Friction provides a grip for the conveyor belts to transfer motion from one part of a machine to another.

(c) Cars, buses and all locomotives will not be able to stop once they are set in motion if the friction was absent. friction provides a braking forces for these vehicles to stop.

pretty sure it's false
