While weight and mass might affect how fast an objects falls, moment of inertia is the key to speed today! Much like a figure skater pulling their limbs in to speed up a spin, the more mass an object ...

The same familiar problems. Pick a step motor that’s too big and you’ll end up with vibration. Too small, and it’ll likely stall out. Then there’s rotor inertia. If inertia is too small, you’ll never ...

Oriental Motor U.S.A. Corp. Proper motor sizing is important in these days of cost consciousness. Oversized motors are luxuries that are not cost effective. But a motor that's too small simply won't ...

Newton's laws of motion, often perceived as abstract, are actually evident in everyday experiences. The first law explains inertia, demonstrated by seatbelts in cars. The second law, F=ma, clarifies ...

A new theory of inertia could explain how NASA is generating thrust with a new drive design, and may even show them how to make it more powerful. Share on Facebook (opens in a new window) Share on X ...
