Q25

#### Read the following sentences carefully, and choose the correct one:

[A]. When you push up box on the floor it undergoes rectilinear motion.
[B]. Measurement involves the comparison of an unknown quantity with a known quantity.
[C]. Motion of needle of a sewing machine is periodic motion.
[D]. All the above.
##### What do you mean by “one oscillation”, “vibratory motion” and “random motion” in 6th Science Chapter 10?

One complete cycle from the point of release to the other extreme and back to the initial point is called one oscillation. A very fast back and forth motion is called vibratory motion. When a body moves in different direction and does not have a fixed path, it is called random motion.

##### How many types of motion is exhibited by the earth moving around the sun as per Class 6 Science ch. 10?

The earth moves around the sun, so it has circular motion. The earth repeats its motion around the sun after regular intervals of time after one year. So, it has periodic motion and the earth rotates on its axis, so it has also rotational motion. Thus, the earth has three types of motion at the same time, circular motion, periodic motion and rotational motion.

##### Can you write, one differences between “circular motion” and “rotational motion” according to class 6 Science chapter 10.

The difference between circular motion and rotational motion is that in circular motion an object as a whole travel along a circular path but in rotational motion, the object spins on its axis.

##### How many types of motion exhibited by the sewing machine, explain as chapter 10 of 6th Science?

The sewing machine has a wheel which rotates on its axle. So, the wheel of a sewing machine shows rotational motion. The sewing machine has also a needle which moves up and down continuously. The needle of sewing machine undergoes a periodic motion. Thus, a sewing machine exhibits two types of motion at the same time, rotational motion as well as periodic motion.
