How are weight and gravitational force related? What is the relationship between momentum and inertia? What is an inertial frame of reference in physics? What type of relationship exists between velocity and centripetal force? How do you find time and velocity in momentum with only force and mass...
Jason Gallivan (l) and Randy Flanagan discuss their latest research findings. Humans have developed sophisticated concepts like mass and gravity to explain a wide range of everyday phenomena, but scientists have remarkably little understanding of how such concepts are represented by the brain. Using ...
You are now familiar with the major players in the universe: space, time, matter, motion, mass, gravity, energy and light. The neat thing about Special Relativity is that many of the simple properties discussed in section 1 behave in very unexpected ways in certain specific "relativistic" sit...
Like other species, we are the products of millions of years of adaptation. Now we're taking matters into our own hands.
Harsh Cornering is a little trickier to both calculate and grasp intuitively. Any time you change velocity you are undergoing an acceleration. When you are turning a corner, this acceleration is 90 degrees from the direction you are travelling, regardless of how tight a turn you are making. Th...

Once aloft, gravity (the weight of the hang glider and pilot) pulls the glider back toward Earth and propels the glider forward, continually causing air to flow over the wing. In addition to the horizontal movement of air, hang gliders can get lift from rising currents of air, such as ...

Little to no gravity can affect how rooting materials function. Different rooting materials and soils are better than others when it comes to water and air distribution -- both key to successful plant growth. Out in space, grainy soils can cause water to scatter and fine soils can prevent air...
