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.
54) Frictional force encountered after commencement of motion is called

Related Engineering Mechanics MCQ with Answers
Answer is:
ratio of limiting friction and normal reaction
Explanation:
The coefficient of friction is defined as the ratio of the limiting friction (F) to the normal reaction (RN) between the two bodies.
Answer is:
proportional to velocity of sliding
Answer is:
mechanical advantage is equal to velocity ratio
Explanation:
An ideal machine is that in which there is no dissipation of energy in any manner. In an ideal machine, the work output is equal to the work input, i.e., efficiency of an ideal machine is 100%.
In ideal machines mechanical advantage is equal to velocity ratio.
