Gravity and friction affect the way you slide down. They also affect every activity that you do, from walking to running, going up and down the stairs, and many more. We naturally encounter gravity and friction and help us with our daily life. Both gravity and friction are kinds of forces. Gravity keeps everything on Earth firmly on the ground. On the other hand, friction is a forcethat resists the movement of an object sliding against another.
