Question

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 be decreased by half.

B.
The acceleration will be quadrupled.

C.
The acceleration will remain the same.

D.
The acceleration will be doubled.

Answer 1

The acceleration varies in direct proportion to the unbalanced force, if mass remains constant.\[\color{green}{\vec{a} \propto \vec{F}}\]

Answer 2

@ghuczek can you elaborate?

Answer 3

The acceleration varies directly with the force. So, if you double the force, the acceleration will double.

Answer 4

@ghuczek So, D?
