First, let’s look at gravity. On the surface of the Earth, the usual model for gravitational force is the object’s mass times the gravitational field (represented by g) where g is about 9.8 Newtons ...

The questions in this quiz are suitable for GCSE physics students studying density, volume and investigating density. If you struggled with the quiz, don't panic - we've got you! You can revise ...

High energy density (HED) physics has critical applications in areas such as inertial confinement fusion and the stewardship of the nation’s nuclear weapons stockpile. Congress has requested that the ...

Figure 1: PIC simulation and spectra from plasma generated by femtosecond pulse irradiation of a vertically aligned array of 55-nm-diameter Ni nanowires. Figure 2: Single-shot M-shell spectra of ...

Researchers have applied physics theory and calculations to predict the presence of two new phenomena -- interspecies radiative transition (IRT) and the breakdown of the dipole selection rule -- in ...

Plasma physics is the study of charged particles and fluids interacting with self-consistent electric and magnetic fields. It is a basic research discipline that has many different areas of ...
