Newton's Second Law

Newton's Second Law

The most important equation in classical mechanics:

F = ma quad Rightarrow quad a = rac{F}{m}

Force ($F$) is measured in Newtons ($\text{N} = \text{kg} \cdot \text{m/s}^2$). Mass ($m$) in kilograms. Acceleration ($a$) in m/s².

Physical Meaning

A net force causes acceleration proportional to the force and inversely proportional to mass. A heavier object requires more force to achieve the same acceleration.

Examples

Net Force

The $F$ in $F = ma$ is always the net force — the vector sum of all forces acting on the object. If you push a block with 50 N and friction provides 20 N opposing, the net force is 30 N.

Your Task

Implement acceleration(F, m) returning acceleration in m/s².
