If it weren't for friction, you would have to place the object on a perfectly flat surface and ensure it wasn't moving even slightly when you let it go to prevent the object from sliding off the surface.
• Frictional energy warms your hands when you rub them together on a cold winter day.
• Friction permits a car to hold a curve. Without the friction between the tires and the road surface, you would not be able to steer around a curve, because the car would want to travel in a straight line. What's more, without friction, the drive wheels would slip and spin and be unable to propel the vehicle.
