Parametric Equations

discussion summary practice problems analytic geometry In previous sections, we discussed how the kinematic variables of distance, displacement, speed, velocity, and acceleration can be used to analyze motion in a straight line. During one-dimensional motion, the objects moving have only one degree of freedom. This is an idealization, of course. When I step out of my apartment on to the ...

Speed velocity and acceleration

Average velocity formula Average velocity formula What’s the difference between two identical objects traveling at different speeds? Nearly everyone knows that the one moving faster (the one with the greater speed) will go farther than the one moving slower in the same amount of time. Either that or they’ll tell you that the one moving faster will get where it’s ...

Average velocity formula with examples

Average velocity formula: Velocity is defined as:”The rate of displacement of a body is called its velocity.”The velocity tells us not only the speed of a body but also the direction along which the body is moving.Velocity of a body is a vector quantity.It is equal to the displacement of a body in unit time.And is represented as: Velocity=displacement/time V=d/t ...

Catching gravity, rolling by

Catching gravity, rolling by gravity: sits a massive laboratory, its two long arms stretching off into the distance. On windy days, tumbleweeds roll by, piling up against the arms’ concrete housing and creating headaches for the lab’s maintenance workers. Inside, though, there is a buzz of activity as scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO) prepare for the most ...

Pulsars speed up by tapping into superfluid core

Pulsars speed up by tapping into superfluid core electromagnetic radiation superfluid A  in the core of a pulsar may cause the poorly understood effect. The work combines radio and X-ray data to determine pulsar masses, and successfully explains glitches that are documented in 45 years’ worth of observational data. “pulses” of broadband electromagnetic radiation at very regular intervals. Born in the ...

European superscope reveals its three ‘first-light’ instruments

European superscope reveals its three ‘first-light’ instruments superscope Theby the European Southern Observatory (ESO), which recently signed agreements for their construction. For the E-ELT first phase – which will begin in 2024 – the superscope will be equipped with the Mid-infrared E-ELT Imager and Spectrograph (METIS); the Multi-Adaptive Optics Imaging Camera for Deep Observations (MICADO); and the High Angular Resolution Monolithic Optical and Near-infrared Integral ...

Gran Sasso steps up the hunt for missing particles Physicists

Gran Sasso steps up the hunt for missing particles Physicists working at the Gran Sasso National Laboratory in central Italy, located 1400 m under the mountain of the same name, are soon to start taking data from two new experiments. Each facility will target a different kind of missing matter: one will search for dark matter while the other will try and detect ...

Pierre Auger cosmic-ray observatory set for expansion

Pierre Auger cosmic-ray observatory set for expansion cosmic-ray  The AugerPrime overhaul will involve installing scintillation detectors alongside the 1660 existing water Cerenkov detectors. This will enable more precise measurements of the mass of particles that make up cosmic rays, as well as help to identify the origin and nature of such particles. The facility, which covers an area of 3000 km2 in Argentina, ...

Dark-matter satellite ushers in new era of Chinese space science

Dark-matter satellite ushers in new era of Chinese space science Dark-matter satellite Scientists in China are preparing the country’s first dark-matter satellite to start taking data following its launch on 17 December 2015 from the Jiuquan Satellite Launch Center. The Dark Matter Particle Explorer (DAMPE), which is also dubbed “Wukong” (Monkey King) after the famous warrior from the 16th-century Chinese novel Journey to the ...

Fixing the Sun’s magnetic sway on cosmic rays

Fixing the Sun’s magnetic sway on cosmic rays magnetic sway Utilizing as of late discharged information from the Voyager I satellite mission, analysts in the US have built up another and precise recipe that portrays the Sun’s impact on enormous beams. Inestimable beams – extremely high-energy charged particles that originate outside of the solar system and travel at nearly light-speed ...
