Newton’s second law can be formally stated as,

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.

This statement is expressed in equation form as,
a=Fnetm
The above equation can be rearranged to a familiar form as
F=ma
Since force is a vector, Newton’s second law can be written as
F→=ma→
The equation shows that the direction of the total acceleration vector points in the same direction as the net force vector.
