# Force

**Formula:** `F = mass × acceleration`

The concept of force is fundamental in physics and represents the interaction that causes an object with mass to change its velocity. This interaction is quantified by the formula ** F = mass × acceleration**. Here,

**represents the force applied to the object,**

*F***is the mass of the object, and**

*mass***is the rate of change of velocity of the object. Force is a vector quantity, which means it has both magnitude and direction. It's measured in Newtons (N), where 1 Newton equals the force required to accelerate a one-kilogram mass by one meter per second squared. This formula is widely used in various fields, such as engineering, for designing structures and vehicles, in astronomy for calculating gravitational forces between celestial bodies, and in biomechanics for understanding forces in the human body.**
