[A]. Rotational motion and Rectilinear motion
[B]. Rectilinear motion and Circular motion
[C]. Rotational motion and Circular motion
[D]. Rectilinear motion and Periodic motion
Q6

#### Sonali is writing some statements but she confused to know whether the statements are correct or not? If you know the answer to this question, then tell her:

[A]. Motion of a stone falling from height is a rectilinear motion.
[B]. Motion of hands of a clock is a circular motion and periodic motion.
[C]. Motion of moon around the earth is a periodic motion.
[D]. All the above.

Q7

#### The girth of a tree can be measured by using a:

[A]. Plastic ruler
[B]. Meter scale
[C]. Meter rod
[D]. Measuring tape
Q8

#### In the last year board examination, Rahul were asked a question where he had to choose the statement which was/were incorrect? Will you be able to answer this question?

[A]. The earth has two types of motion at the same time as circular motion and rotational motion.
[B]. A bicycle moving on a straight road has two types of motion as rotational motion as well as rectilinear motion.
[C]. The sewing machine has a wheel which rotates on an axle, so the wheel of a sewing machine shows rotational motion.
[D]. The sewing machine has also a needle which moves up and down continuously, so the needle of sewing machine undergoes a periodic motion.

Q9

#### Consider the following statements and choose the correct one:

[A]. One complete cycle from the point of release to the other extreme and back to the initial point is called one oscillation.
[B]. When a body moves in different direction and does not have a fixed path, it is called random motion.
[C]. An object that does not change its place or position with time, relative to its surrounding is said to be stationary or at rest.
[D]. All the above.
Q10

#### Sweety is writing some statements but she confused to know whether the statements are correct or not? If you know the answer to this question, then tell her:

[A]. To guess the amount of anything without actual measurement, called absolute unit.
[B]. The rate of movement of an object is determined by measuring the distance travelled with time.
[C]. When a body moves in different directions and does not have a fixed but it is called a random motion.
[D]. When object moves in the same direction and covers equal distance in a given interval of time then such motion is called translational motion.
##### What do you mean by “one oscillation”, “vibratory motion” and “random motion”?

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?

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”.

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?

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.
