Since there is no strict distinction between mass (i.e. density) and weight in industry, simply speaking, the specific gravity of an object is the ratio of its weight to its volume.That is, the weight per unit volume of an object, and its unit is g/cm. Determining the specific gravity...
The ability of a gyroscope to "defy gravity" is baffling! How can it do that? This mysterious effect is precession. In general, precession works like this: If you have a spinning gyroscope and try to change the orientation of its spin axis, the device will respond by changing its orient...
"It makes things fall," children may answer if you ask what gravity does. They might have a little more trouble telling you what this enigmatic force actually is. Scientists don't fully understand it either, but in simple terms, gravity is an invisible attractive force that causes objects to...
Figuring out the weight and balance by calculation alone simply means that you do the math for everything—all of the numbers are filled out line by line. The other methods simply make your life a little easier by giving you some of that information quickly. Understanding the calculation metho...
Here's how it would work out on the street. Imagine that you're riding a motorcycle on the interstate. In front of you, blocking the right half of your lane, is a wreck or some other obstacle. If you're a novice rider, you might be tempted to push on the right side of the hand...
"You've got to figure out where each bullet went. The old way of doing it was, 'Well, he's got 10 holes on the front, there are eight holes on the back, and there's two bullets inside, we're done' legal system won't accept that anymore." A part of a medical examiner's ...
Now, you know exactly what to test. Focuses Your Research: It makes it easier to gather relevant data, so you’re not wasting time on unrelated information. Shows Your Thinking: It lets others see what you’re trying to figure out, making your experiment or paper much easier to follow. ...
Use a full grip so you can Deadlift more weight. If you “don’t feel your muscles” as well with the full grip, add weight on the bar. You’ll feel it once things get heavy. Most people make the mistake of gripping the bar in the middle of their palms. Gravity pulls the bar ...
Urbanization and climate change are contributing to severe flooding globally, damaging infrastructure, disrupting economies, and undermining human well-being. Approaches to make cities more resilient to floods are emerging, notably with the design of flo
