Force Force is a push or pull which tends to change the state of rest or of uniform motion , the direction of motion, or the shape and size of a body. Force is a vector quantity. The SI unit of force is Newton, denoted by N. One N is the force which when acts on a body of mass 1 kg produces an acceleration of 1 m/s².

Jan 11, 2024 · Force is a physical quantity that describes the interaction between objects. It is what causes objects to accelerate or change their state of motion. There are four main types of force: gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force.
Definition of Force. What we have been calling “pushes and pulls” or “external influences” is called force in physics. Most people have an intuitive idea of what force is, and like so many other physics concepts, this intuition is very likely wrong. We'll start by saying what force is not, then move on to its definition.
According to quantum field theory, the forces between particles are mediated by other particles, and the fundamental forces can be described by the exchange of virtual force-carrying particles: the strong nuclear force mediated by gluons; the electromagnetic force by photons; the weak nuclear force by W and Z bosons; and gravity by hypothetical ...
Forces are responsible for all the interactions between particles and objects. They can be divided into two categories: contact forces and non-contact forces. Gravity - AQA
