# What Is the Formula for Effort Force?

**The formula to calculate force is: force = mass x acceleration, or F = m x a, where force and acceleration have both magnitude and direction.** A force is an interaction that acts upon the state of motion of an object.

Sir Isaac Newton's First Law of Motion states that an object in uniform motion tends to continue that uniform motion unless acted upon by an external force. When a force acts upon an object, it influences its state of motion; this is called work and is measured by finding the displacement of the object or the change in its potential or kinetic energy.
