Friction is always present when two solid surfaces slide along each other
- sliding friction is called kinetic friction
- static friction applies when two surfaces are at rest
The net force towards the center of circle
If the road flat ,force is supplied by friction
If the tires not slip : the friction is static
If the tires start to slip : the friction is kinetic
atan : dv/dt
falls with constant
velocity called terminal velocity
