Inertia: the resistance an object has to a alter in its state of motion.
Newton's first law of motion declares that force is NOT required to keep an object in motion.
Slide a book across the table and watch it slide to a rest position. The book in motion on the tabletop does not come to a rest position due to the absence of a force; rather it is the presence of a force - the force of friction - that brings the book to a rest position.

A scooterist is racing at a speed of 72 km per hour. If the radius of the wheel is 20 cm, find the angular speed of the wheels. Ans) 72kmph=20m/s 20cm=0.2m; v=rw w=v/r w=20/0
Can fibers be bent at right angle? Fibers cannot be bent at right angle. All fibers should be bent with a radius that will not alter the internal architecture of the fiber. For
