Question

Define rotatory motion with a suitable example.

​

Answer 1

a. When an object falls freely to the ground, it is under the effect of a constant force known as force of gravity. No other forces act on it. Hence, from Newton's second law of motion, we can say that this constant force of gravity accelerates the the freely opposite, their effects do not get cancelled because these action and reaction forces do not act on the body. ball has s ball than a cricket ball moving with the same velocity.

b. Even though the magnitudes of action force and reaction force are equal and their directions are opposite, their effects do not get

cancelled.

c. It is easier to stop a tennis ball as compared to a cricket ball, when

both are travelling with the same velocity.

d. The velocity of an object at rest is considered to be uniform...The answer for the given riddle is pencil.

Explanation:

The hints for the riddle are iam from a mine and wood is major hint.

Generally natural resources like coal, diamond, graphite, iron are from mines.

In the above natural resources generally graphite is surrounded by wood and daily used by us as pencil for writing.

Rotatory motion is the motion that occurs when a body rotates on its own axis. A few examples of the rotatory motion are as follows:

1. The motion of the earth about its own axis around the sun is an example of rotary motion.
2. While driving a car, the motion of wheels and the steering wheel about its own axis is an example of rotatory motion.
