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

No, the elephant has lots more mass and inertia than the mouse. In other words, the mouse would bounce off of you and you'd hardly notice. You would bounce off of the elephant and he'd hardly notice.

Yes. Weight is only present in gravity.
But no, they would not have the same effect if they bumped into you. The elephant would have more inertia and momentum which are only dependent on the mass.

they have the same velocity but they have different momentum(mass*velocity)..momentum is the key factor in collisions...
whichever body that has greater momentum has a smaller change in its momentum after the collision...
so if u bump into a rat..uve got lots more momentum than the rat..so ur change in momentum will be very little..and the rat bounces off..
its the otherway round with the elephant and ull bounce back...

they would both be weightless because weight is gravity. but the bumping in to you part i guess would happen because of some small gravatational pull? so the elephant would still be more forceful. that makes sence to me.

check newton,s law,s.....force= mass x acceleration......has nothing to do with weight......just mass.
