This equation represents Newton’s Second Law of Motion: F = ma. It shows the relationship of force, mass, and acceleration. How will the acceleration of an object change if the force acting on it is doubled, but the mass of the object remains the same?

A.
The acceleration will remain the same.

B.
The acceleration will be decreased by half.

C.
The acceleration will be doubled.

D.
The acceleration will be quadrupled.

F = ma

We consider the force doubling and mass remaining the same:

2F = ma

We see that acceleration originally is: a = F/m
Now we see that acceleration is: a = 2F/m

So, the acceleration has doubled.
