What is friction?

The video explains why cars skid on icy roads, focusing on the concept of friction. Friction is a force that acts in the opposite direction of movement, slowing objects down. The amount of friction depends on the surface type; smooth surfaces create less friction, while rough surfaces create more. On icy roads, the surface becomes smoother, reducing friction and increasing the likelihood of skidding.
