C5 : Friction , Circular Motion & Drag Forces
5.1 : Application of Newton's Laws Involving Friction
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
5.3 : Dynamics of Uniform Circular Motion
5.4 : Highway Curves :
Banked & Unbanked
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
5.6 : Velocity-Dependent Forces : Drag & Terminal Velocity
falls with constant
velocity called terminal velocity
5.2 : Uniform Circular Motion, Kinematics
5.5 : Nonuniform Circular Motion
extra
atan : dv/dt
