Long-necked plesiosaurs were thought to be slow swimmers. But new research suggests the animals’ large size helped them overcome water resistance.
When an object experiences a force, its change in motion — or acceleration — depends on its mass.
This thin, flexible and lightweight loudspeaker could reduce noise in loud spaces. It also might enable listeners to experience sound in new ways.
Two types of friction help determine how quickly a line of dominoes collapses, computer modeling shows.
Inertia is the tendency of objects to resist changes in their motion.
Scientists discover that orb-weaving spiders listen with their legs, detecting sound vibrations that travel through their silken webs.
A handful of rules can describe the route some object repeatedly takes around another in space. Calculating that path, however, can be quite complex.
Four fundamental forces control all interactions between matter, from the smallest subatomic particles to the largest structures in the universe.
Scientists are using living cells and tissue as building blocks to make robots. These new machines challenge ideas about robots and life itself.
