By the Pythagorean theorem, the magnitude of the resultant force is [(-10) 2 + (-8) 2] 1/2 ≈ 12.8 N, which is also the magnitude of the equilibrant force. The angle of the equilibrant force can be found by trigonometry to be approximately 51 degrees north of east. Because the angle of the equilibrant force is opposite of the resultant force ...

This is a glossary for the terminology applied in the foundations of quantum mechanics and quantum metaphysics, collectively called quantum philosophy, a subfield of philosophy of physics. Note that this is a highly debated field, hence different researchers may have different definitions on the terms.
Notes [ edit ] ^ The values are given in the so-called concise form ; the number in parentheses is the standard uncertainty and indicates the amount by which the least significant digits of the value are uncertain.
In physics and engineering, a resultant force is the single force and associated torque obtained by combining a system of forces and torques acting on a rigid body via vector addition. The defining feature of a resultant force, or resultant force-torque, is that it has the same effect on the rigid body as the original system of forces. [1]
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.
