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.
Answers
Answer:
according to third law of motion, if the man experiences a push towards right, it means the capsule is being pushed left from some external force. This is a reality not simply a feeling
Explanation:
This phenomena is well explained from Newton laws of motion;
Newton's three laws of motion may be stated as follows:
Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it.
Force equals mass times acceleration
For every action there is an equal and opposite reaction.
Now as long as the man inside the capsule does not feel any push, it will remain in that steady state.
And according to third law of motion, if the man experiences a push towards right, it means the capsule is being pushed left from some external force. This is a reality not simply a feeling
Now quoting an alternate example;
When you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.
Another example is of a rocket being launched in space.During launch, the burning fuel exerts a downward force, and the reaction force pushes the rocket into the air
Answer:
It is a reality.
Explanation:
The world moves in a circular path. Hence, it exhibits a centripetal force. The direction of the centripetal force is towards the centre. Now, if we move to space suddenly where there is no such force, therefore it takes the body time to adjust to such circumstances.
It is nothing but the withdrawal of the centripetal force and the gravitational force of attraction of the earth. A similar thing is felt when we suddenly change the direction on the top of a merry goes round.
