Final answer:
Force is directly proportional to the mass and acceleration of an object.
Step-by-step explanation:
Force is directly proportional to the mass of an object and the acceleration acting on it, according to Newton's second law of motion. This relationship is expressed by the equation F = ma, where F represents force, m represents mass, and a represents acceleration.
For example, if the mass of an object is doubled while the acceleration remains constant, the force acting on the object will also double. Similarly, if the acceleration of an object is doubled while the mass remains constant, the force acting on the object will also double.
