Question

which types of friction is seen when two bodies are in contract but do not move? 1=static.2=sliding.3=rolling.,4=fluid.​

Answer 1

1. Static friction - as in static friction, the frictional force resists force that is applied to an object, and the object remains at rest until the force of static friction is overcome. In kinetic friction, the frictional force resists the motion of an object.
