An elephant and a mouse would both have zero weight in gravity-free space If they were moving toward you with the same speed would they bump into you with the same effect Explain?

Weight is mass*gravity, in zero gravity objects have zero weight. But they still have mass! When one object bumps another they under go a collision. Which can be explained by transfer of energy or conservation of momentum. In the case of energy, KE=1/2mv2 the mouse and the elephant have different masses so therefore different kinetic energy. Or in terms of momentum (mass*velocity), again the mouse and elephant have different masses and therefore different momentums at the time of impact. Therefore the reaction you feel will be different.

Can an elephant have the same momentum has a golf ball?
Momentum, in classical terms, is defined as mass x velocity. So, theoretically, an elephant could have the same momentum as a golf ball if the golf ball (small mass) is moving very, very fast, and the elephant (large mass) is moving very, very slowly. If the product of the mass x velocity is the same, then the momentum can be the same.
What are Reference points to explain that train is moving?
A person standing on the ground. For the person on the train, ground is moving and the train is stationary.
What is hall effect explain briefiy?
Deflection of moving carriers in a semiconductor perpendicular to a magnetic field.
How do you explain the effect of balanced forces on the state of motion of an object?
A balanced group of forces acting on the object has no effect on its motion. The object continues moving in a straight line at constant speed.

What is the effect of a magnetic field on a stationary electric field?
The magnetic field will have no effect on a stationary electric charge. ( this means that the magnetic field is also stationary. ) If the charge is moving , relative to the magnetic field then there might be an effect, but the size and direction of the effect will depend on the direction of the electric charge as it moves through the field. If the charge is moving parallel to the field there will be no effect on it. If the charge is moving at right angles to the field then it will experience a force that is mutually orthogonal to the field and direction of the motion. You really need diagrams to properly explain this

What is the effect of balanced forces on an object that is not moving?
A group of balanced forces adds vectorially to zero, so has no effect on any object, whether it's moving or not moving.

Why is Pakistan trying to derail India's growth?
I don't think Pakistan or for that matter any country can derail a huge country like India. What will happen when you throw a twig in front of a slow moving elephant?? It will get crushed but will not stop the elephant from moving ahead.
What effect does time have on the speed of a moving object?
Time in no way has an effect on speed.

Can you explain What is the effect of moving to another country?
Nearly everything would be different and people may act in a weird way because it's their culture and the person that moved may take a while to adjust.
