Weight is the force acting on an object due to gravity - it has the unit newtons (N) and acts towards the centre of a gravitational field. The weight of an object can be measured using a calibrated ...

The weight of an object and its mass are directly proportional. For a given gravitational field strength, the greater the mass of the object - the greater its weight is. Weight can be calculated using ...

In quantum mechanics, charged particles like electrons can be sensitive to the effects of electromagnetic fields, even when placed in a region where both the electric and the magnetic fields are zero.

Exact solutions in electromagnetic fields and gravitational dynamics offer a rigorous window into the fundamental interactions that govern our universe. By applying advanced mathematical ...

Even teeny objects obey the law of gravity. A gold ball just 2 millimeters wide, with a mass of about 90 milligrams, is now the smallest object to have its gravitational pull measured. Observations of ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...
