Answer is:
the friction force acting when the body is just about to move
Answer is:
less
Explanation:
Static Friction The friction experienced by a body, when it is at rest is known as static friction.
Dynamic Friction The friction experienced by a body, when it is in motion is called dynamic friction. Dynamic friction is also called as kinetic friction.
Dynamic friction always less than static friction.
The ratio of static friction to dynamic friction is always greater than one.
