Forces in Physics Quiz

Force is an influence that can cause an object to change its velocity. It is represented mathematically as a vector quantity, often denoted by the symbol $F$.

The SI unit of force is the newton (N), and force is often represented by the symbol $F$.

Force plays a central role in classical mechanics by figuring in all three of Newton's laws of motion, which specify that the force on an object with an unchanging mass is equal to the product of the object's mass and the acceleration that it undergoes.
