### 7th Class Science 5th Lesson Motion and Time Short Questions and Answers

Question 1.
How do you decide whether any object is in motion or at rest?

1. We can decide whether any object is in motion or at rest by observing its position with respect to its surroundings.
2. If an object is not changing its position with respect to the surroundings then we can say that the object is in rest.
3. We can say an object is in motion when it is changing its position with respect to the surroundings.

Question 2.
Write the differences between distance and displacement.

 Distance Displacement 1. The total length of the path travelled by an object between two places is called distance. 1. It is the shortest distance between the starting and final positions of a moving object. 2. It depends upon the path. It changes according to the path taken. 2. It does not depend upon the path and it only depends upon the initial and final position of the body. 3. It can be measured along the path. No matter whether it’s a straight or a non-straight path. 3. It can only be measured along a straight path no matter what the path followed by object. 4. To calculate it, the direction is not considered. So it does not depend on direction 4. To calculate it, the direction is taken into consideration. So it depend on direction. 5. Its value never become Zero. 5. Its value may become Zero. 6. Its value is always more than or equal to the value of displacement. 6. Its value is always less than or equal to the value of distance.

Question 3.

4. Stop clocks are used to measure shorter time intervals between two events accurately.

Question 4.
What is translatory motion? Explain different types of translatory motions?

1. If all points of a moving object move through the same distance in same direction, then the motion is said to be translatory motion.

2. Observe the movement of hands in a wall clock and the movement of a butterfly in a garden.
3. Measure the angle between two successive positions of the minute hand in a wall clock.
4. You can observe that the change in its position is same for every minute.
5. But in the case of the butterfly, the change in its position is not constant while it is . flying from one flower to another in the garden.
6. We understand that the minutes hand in wall clock covers equal distances in equal intervals of time and the butterfly covers unequal distances in equal intervals of time.
