compare the translational and rotational quantities
Answers
Answer:
Translational motion is motion that involves the sliding of an object in one or more of the three dimensions: x, y or z. But an object can still be moving even when it's just sitting at a particular x-, y- and z-coordinate; it can still spin.
Rotational motion is where an object spins around an internal axis in a continuous way. An ice-skater can do this by spinning on the spot. She will give herself rotational energy. And because energy is always conserved and a smaller object must spin faster to have the same energy, when she moves her arms in towards her body, her rotation speed will increase - the spinning will get faster and faster.
This is also the reason that tornadoes spin so fast. Before the tornado forms, the air, in general, is rotating at a large radius. But if that radius decreases, the spinning gets faster, until you have a storm with incredible power.
