For ease of understanding and convenience, 21 SI derived units have been given special names and symbols, as shown in Table. Definition of Force … Torque, also called moment of a force, in physics, the tendency of a force to rotate the body to which it is applied. The second, unit of time — symbol s. unit of force is Newton. The coefficient of viscosity η is defined as the tangential force F required to maintain a unit velocity gradient between two parallel layers of liquid of unit area A. Join now. Metric: Unit of force=Newton=(kg*m)/s^2. State the SI Unit of Work and Define it. Apart from that, there are few other ways we can express the unit of measurement of force. English: Unit=poundal=(lb*ft)/s^2. See more. A unit of force is an arbitrary measurement that we designate as "1" (unit), so that all other measurements of force are multiples of that unit.. A force that acts upon an object can cause the acceleration of the object. Every liquid has its own specific viscosity and the measure of this attribute is called the coefficient of viscosity.
