You are inside a closed capsule from where you are not able to see anything about the outside world. Suddenly you feel that you are pushed towards your right. Can you explain the possible cause (s)? Is it a feeling or a reality? Give at least one more situation like this. |

Answer» 1. In a capsule, if we suddenly feel a push towards the right it is because the capsule is in motion and taking a turn towards the left. 2. The push towards the right is a feeling. In reality, when the capsule is beginning its turning motion towards the left, we continue in a straight line. 3. This happens because we try to maintain our direction of motion while the capsule takes a turn towards the left. 4. An external force is required to change our direction of motion. In accordance with one of the inferences from Newton’s first law of motion, in the absence of any external force, we continue to move in a straight line at constant speed and feel the sudden push in the direction opposite to the motion of the capsule. 5. Example: While travelling by bus, when the bus takes a sudden turn we feel the push in the opposite direction. |
