When you double the force acting on an object and keep the mass constant, the acceleration doubles as well.

Here's why:

* Newton's Second Law of Motion: This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically, this is represented as:

F = m * a

where:

* F = Force

* m = Mass

* a = Acceleration

* Doubling the Force: If you double the force (F), and the mass (m) remains constant, the only way to keep the equation balanced is for the acceleration (a) to also double.
