Driving a spacecraft around a planet isn’t anything like driving on a planet. A physicist explains orbital navigation.

I assume the laws of physics still apply in "unintended acceleration." In particular, F=ma, "force equals mass times acceleration," implies that acceleration depends on a continued applied force. With ...

The questions in this quiz are suitable for GCSE physics students studying terminal velocity, Newton's first, second and third laws and braking. If you struggled with the quiz, don't panic - we've got ...

Most explanations rely on "dark energy" to explain the Universe's accelerating expansion rate, but a new study takes a different path.

In a fixed-field alternating-gradient (FFAG) accelerator, eliminating pulsed magnet operation permits rapid acceleration to synchrotron energies, but with a much higher beam-pulse repetition rate.

The shocking discovery that the universe is expanding at a faster and faster rate has taken the 2011 Nobel Prize in physics. Three American-born astrophysicists will divide the $1.5 million prize, ...
