Friction acts as a centripetal force in the case of a car turning. The friction creates a tangential force allowing the car to turn.
Tension can act as a centripetal force in the case of circles. Such as swinging a mass on a string, the tension force allows it to move in a curved path.
Gravity acts as a centripetal force in the case of satellites. The gravity keeps the satellite within the orbit.
Answer:

The elephant and the mouse having zero weight in a gravity free space will not bump into you at the same effect.
<u>Explanation:
</u>
When both are in a gravity free space, the weights are zero, as we know that the
But when they will acquire the speed of same magnitude, say v, their different masses will acquire different momentum, which will make the difference in effect while bumping.
And as we know 
Therefore, effect of impact by elephant will be more than that of mouse
. An elephant breaking into you will take you back faster than a mouse in space hits you.
