If the force acting on a body is doubled, then the acceleration produced will also double.

This is directly related to Newton's Second Law of Motion, which states:

Force (F) = Mass (m) x Acceleration (a)

This means:

* Acceleration is directly proportional to the force applied. If you double the force, you double the acceleration.

* Acceleration is inversely proportional to the mass. If you double the mass, you halve the acceleration.

Example:

If a force of 10 Newtons produces an acceleration of 2 m/s², then doubling the force to 20 Newtons will produce an acceleration of 4 m/s².
