# How is acceleration related to force?

##### 1 Answer

Force is **directly proportional** to acceleration.

#### Explanation:

This is brought around from the derivation formula of **Newton's Second Law of Motion** which states; F=ma. Here, ' **F** ' is the resultant force, ' **m** ' is the mass of the object in motion and ' **a** ' is its acceleration in the direction of the resultant force.

For example, imagine applying a **500 N** resultant force to a small car, and applying a **1000 N** resultant force on another small car of the **same mass** . Which one will move faster?

Obviously, the one where a larger force is applied. (Keep in mind that mass is constant. Because mass is inversely proportional to acceleration.)
