So she can reach faster
you will need it when you push a trolley.
Friction can be very useful in your life. You need low friction when you ski. If you have high friction you cannot glide easily on the snow. You can also use low friction when you ice skate. If you have high friction you cant glide across the ice. When you use your laptop your keypad has to be able to glide. Some examples of high friction are erasing with your pencil, rubbing your hands together etc.
we need friction because if there were no friction the objects around us will slide

You need high friction so your feet and hands don't slip.

Friction is high on a carpet.
Friction is considered a force because it acts on an item and causes changes, which is what a force is. Nothing would happen if the item was in an area where friction was not possible or if friction was where an object was not since they need each other to exert external effort.

In the bearings, where you want as little friction as possible.
Example of high friction is a really rough surface like sandpaper.
