When the wheel rotates at a high speed, the mud sticking to the wheel flies off tangentially, this is due to inertia of direction. If order that the flying mud does not spiral the clothes of passer by the wheels are provided with mudguards .

Why does a speedy motor cyclist bends towards the centre of a circular path while taking a turn on it?
So that in addition of the frictional force, the horijontal component of the normal reaction also provides the necessary centripetal forces.

Weight of the water and bucket is used up in providing the necessary centripetal force at the top of the circle.

See lessAn athlete runs a certain distance before taking a long jump. Why?
So that inertia of motion may help him in his muscular efforts to take a longer jump.

See lessBodies of larger mass need greater initial effort to put them in motion. Why?
As F = ma so for given a, more force will be required to put a large mass in motion.
As F = ma so for given a, more force will be required to put a large mass in motion.
See lessA body is acted upon by a number of external forces. Can it remain at rest?
Yes, if the external forces acting on the body can be represented in magnitude and direction by the sides of a closed polygon taken in the same order.
