Answer:
Explanation:
Force = mass x acceleration

Force is always vector and acceleration also vector but the mass is a saclar quanity.
here, the direction of force vector is same as the direction of acceleration vector but the magnitude of force depends on the magnitude of mass of the body.
Is mass is more, force is also more.
Thus, the mass is like an indicator of the magnitude of force.
When temperature decreases the atoms(or molecules) within the substance begin to slow down.
