The force unit is called a newton (N), and is defined as the force required to accelerate a mass of 1 kg at a rate of 1 meter/sec. Mathematically expressed;1 N = (1 kg)(1 m/s²) or 1 N = 1 kg.m/s²Even if the math is a bit beyond you, you can note that the SI...
Torque is the twisting force that tends to cause rotation. It is the measure of how much a force acting on an object causes that object to rotate. Visit to learn how to calculate torque along with its formula, meaning and applications.
In Germany, scientists are trying to observe dark matter in a bold new way: by creating it. ALPS II, an experiment at the Deutsches Elektronen-Synchrotron (DESY) in Hamburg, consists of a 250-meter tunnel with an optical cavity. This cavity amplifies a laser that is exposed to an intense...
Thanks to school, most people know how long a foot or a meter is — we are comfortable with these units because we use them every day. Light-years, not so much. Same thing with miles and kilometers — these are nice, human increments of distance that our minds can easily understand. ...
Inductance is defined as the property of an electric conductor which causes an electromotive force that is generated due to a change in the current flow. There are two types of inductance: self-inductance and mutual inductance.
