Force (physique) — Wikipédia
WebbA force is any influence that causes an object to undergo a change in speed, a change in direction, or a change in shape, and is defined in the GameMaker physics world the same as we define gravity, by getting the vector from the two xforce/yforce components. WebbForces are used to push or pull stationary objects, to stop moving objects, to change direction of moving objects. Forces always exist in pairs: a force of action and a force of … 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 … Visa mer 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. … Visa mer 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 Visa mer 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 distances, and are responsible for the … Visa mer 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 arbitrary reference point as the cross-product: Torque is the … Visa mer Since antiquity the concept of force has been recognized as integral to the functioning of each of the simple machines. The Visa mer Since forces are perceived as pushes or pulls, this can provide an intuitive understanding for describing forces. As with other physical concepts (e.g. temperature), … Visa mer Some forces are consequences of the fundamental ones. In such situations, idealized models can be used to gain physical insight.
