What two variables is acceleration dependent on? What is the relationship between these variables and acceleration? (i. e. if you increase one variable what happens to the acceleration?

Anyone please help

the net force acting upon the object and the mass of the object. The acceleration is always in the same direction as the The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

when one variable increases, the other variable decreases. The greater the mass of an object, the less it will accelerate when a given force is applied. For example, doubling the mass of an object results in only half as much acceleration for the same amount of force

truck y has a greater velocity than truck x.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
