Question

Can you explain the answer of this question below:&lsquo;A body can be at rest and in motion at the same time&rsquo; the above statement isA:falseB:trueC:partially trueD:Partially false.The answer is A.

Answer

Yes, possible. It will depend on the frame of references. Suppose you are in a train and the train is moving but you are sitting still in the train. Your copassenger will see you still i.e. in rest but someone from the station or outside of the train will see you to move with the train. So you are in rest as well as in motion in different frame of references. The ans is not a

Answer

Answer B is right answer because if u r in aeroplane then u r in rest as compared to people sitting in aeroplane and u r in motion as compared to bird that flying outside the aeroplane . it means that motion is relative

Answer

Understanding Motion Types
When analyzing the motion of a body, it’s crucial to differentiate between various types of motion. The question states that if a body does not rotate, then its motion is translational. Let's break down the options to understand why 'translational' is the correct answer.
Types of Motion
- Translational Motion: This refers to the motion of an object moving from one place to another without any rotation. In translational motion, all parts of the object move in the same direction and cover equal distances in equal intervals of time.
- Rotatory Motion: This type of motion involves an object rotating around an axis. If a body does not rotate, it cannot exhibit rotatory motion.
- Vibratory Motion: This is a type of motion where an object moves back and forth around a central point. While it does not involve rotation, it is also distinct from translational motion.
Why 'Translational' is Correct
- Since the question specifies that the body does not rotate, the only remaining option is translational motion.
- Translational motion can occur in a straight line or along a curved path, but it fundamentally involves no rotation.
- Examples include a car moving on a road or a ball rolling straight without spinning.
Conclusion
In conclusion, if a body does not rotate, its motion is classified as translational. This is why the correct answer to the question is option 'D'. Understanding these concepts is essential in physics, especially in Class 9 studies, as it lays the groundwork for more complex topics in mechanics.

Answer

Answer a is false because while moving in a road in a car you observe that the people outside are moving but in fact you are moving and outside people are at rest
