The friction experienced by a body, when at rest, is known as Dynamic friction Static friction Limiting friction Coefficient of friction TRUE ANSWER : ? YOUR ANSWER : ?
The moment of a force Is equal to the product of force acting on the body and the perpendicular distance of a point and the line of action of the force Is equal to twice the area of the triangle, whose base is the line representing the force and whose vertex is the point, about which the moment is taken All of these Is the turning effect produced by a force, on the body, on which it acts TRUE ANSWER : ?
