The greater mass of an objectWhich is the greater amount of force needed to accelerate the object 

Mass is inversely proportional to acceleration. The greater the mass, the smaller the accelaration.

Explanation:

(First of all, what?)

According to classical mechanics, F=ma where F is the force, m is the mass of the object and a is it's acceleration. Rearranging, we get F/m=a

explanation:

crosscutting concepts have application across all domains of science. as such, they are a way of linking the different domains of science. they include patterns; cause and effect; scale, proportion, and quantity; systems and system models; energy and matter; structure and function; and stability and change.
