Aug 23, 2024 · Force, in mechanics, any action that tends to maintain or alter the motion of a body or to distort it. The concept of force is commonly explained in terms of Isaac Newton’s three laws of motion. Because force has both magnitude and direction, it is a vector quantity.

A force is an influence that can cause an object to change its velocity unless counterbalanced by other forces. The concept of force makes the everyday notion of pushing or pulling mathematically precise. Because the magnitude and direction of a force are both important, force is a vector quantity.
Jan 10, 2020 · Updated on January 10, 2020. In science, force is the push or pull on an object with mass that causes it to change velocity (to accelerate). Force represents as a vector, which means it has both magnitude and direction. In equations and diagrams, a force is usually denoted by the symbol F.

May 27, 2024 · There are only four known fundamental forces, which are the gravitational force, the Coulomb force, the weak nuclear force and the strong nuclear force. Furthermore, there are many mechanisms and phenomena, which can result in a variety of forces and force characteristics like spring forces and contact forces.
Sep 12, 2022 · An intuitive definition of force —that is, a push or a pull—is a good place to start. We know that a push or a pull has both magnitude and direction (therefore, it is a vector quantity), so we can define force as the push or pull on an object with a specific magnitude and direction.
In mechanics, a force is that which causes a change in velocity or, if you prefer, that which causes an acceleration. When more than one force acts on an object it is the net force that is important. Since force is a vector quantity, use geometry instead of arithmetic when combining forces.
