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

F = m * a

Where:

* F is the net force acting on the object

* m is the mass of the object

* a is the acceleration of the object

From this equation, we can see that:

* If you keep the mass (m) constant and double the force (F), you will double the acceleration (a).

Examples:

* Pushing a box: If you push a box with twice the force, it will accelerate twice as fast.

* Gravity: If you take an object to a planet with twice the gravitational pull, it will experience twice the acceleration due to gravity.

Therefore, to double the acceleration without changing the mass, you need to apply twice the net force.
