In physics, force is a quantitative measure of the interaction between two objects, which results in the acceleration of those objects. Force is defined as any influence that causes an object to undergo a change in motion or deformation.
Force is often described in terms of its magnitude (how strong it is), its direction (which way it is acting), and its point of application (where it is acting). The unit of force in the International System of Units (SI) is the newton (N).
There are many types of forces, including gravitational, electromagnetic, and nuclear forces. Some common examples of forces that we encounter in our everyday lives include frictional forces (such as when we rub our hands together), gravitational forces (such as when objects fall to the ground), and tension forces (such as when we pull on a rope). Understanding the principles of force is essential in many fields, including physics, engineering, and mechanics.
