What is the weight of a body what is the SI unit of weight?
The SI unit of weight is the same as that of force: the newton (N) – a derived unit which can also be expressed in SI base units as kg⋅m/s2 (kilograms times metres per second squared).
What called weight?
The weight of an object (or the weight of an amount of matter) is the measure of the intensity of the force imposed on this object by the local gravitational field. Unfortunately the common terms used to describe the weight of an object are units of mass such as kilograms or pounds.
Do fields have mass?
magnetic fields are produced by charged particles in motion, and depend on the charge and velocity of these particles, but not on their mass. Magnetic fields are ‘polar’ fields with a North and South polarity. Gravitational fields have no polarity at all.
Is everything made of fields?
Carroll’s stunner, at least to many non-scientists, is this: Every particle is actually a field. The universe is full of fields, and what we think of as particles are just excitations of those fields, like waves in an ocean. An electron, for example, is just an excitation of an electron field.
Is everything on earth made of energy?
The quantum theory researchers discovered the answer: Not only do particles consist of energy, but so does the space between. This is the so-called zero-point energy. Therefore it is true: Everything consists of energy.
How many fields are there?
The quarks and leptons are fermions, which is why they have antimatter counterparts, and the W boson comes in two equal-and-opposite varieties (positively and negatively charged), but all told, there are 24 unique, fundamental excitations of quantum fields possible.
