In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

- Force is an external cause which tends to change the state of rest or motion, or it is something that can change the shape and size of any object.
According to Newton's second law of motion, force is equal to the product of mass and acceleration, i.e.,
- The SI unit of force is newton (N). It is named after the mathematician, Sir Isaac Newton.
