How FRICTION affects motion?
• if you roll a ball along the floor or ground, it will slow down and stop even though no apparent force is being applied to it. The ball slows down and stops because of friction. • Friction slows down a moving object. Friction occurs when two objects rub against each other. • • A car that runs on a very rough road slows down due to friction. However, on a smooth road, it travels fast. • A smooth surface has a very few bumps and hollows. There is less friction on a smooth surface. A running object can glide or move continuously with very little force. • • Smooth surface produces less friction and allows shoes and tires to slip. • On a rough surface, there are more bumps and hollows. When you push the cart on a rough road, it will travel slowly. There’s more friction acting on the moving cart. The rougher the surface, the more friction there is, thus, the slower an object moves. • • Friction is lesser on a smooth, shiny surface. • Friction is greater on a rough surface. • Advantages and
