In physics, a force is an influence that causes the motion of an object with mass to change its velocity (e.g. moving from a state of rest), i.e., to accelerate. It can be a push or a pull, always with magnitude and direction, making it a vector quantity. It is measured in the SI unit of newton (N) and represented by the … See more Philosophers in antiquity used the concept of force in the study of stationary and moving objects and simple machines, but thinkers such as Aristotle and Archimedes retained fundamental errors in understanding force. … See more Sir Isaac Newton described the motion of all objects using the concepts of inertia and force, and in doing so he found they obey certain conservation laws. In 1687, Newton published his thesis Philosophiæ Naturalis Principia Mathematica. In this work Newton set out … See more All of the known forces of the universe are classified into four fundamental interactions. The strong and the weak forces act only at very short … See more Forces that cause extended objects to rotate are associated with torques. Mathematically, the torque of a force $${\displaystyle {\vec {F}}}$$ is defined relative to an … See more Since antiquity the concept of force has been recognized as integral to the functioning of each of the simple machines. The mechanical advantage given by a simple machine allowed for less force to be used in exchange for that force acting over a greater … See more Since forces are perceived as pushes or pulls, this can provide an intuitive understanding for describing forces.
