Explain why a graph of acceleration versus the reciprocal of the total mass must pass through the origin when the net force is constant.

An illustration of the letter 'A' in a speech bubbles

From Newton's Second Law we get

a = F/m  or

1/m = (1/F)a

If F is a non-zero constant, then (1/F) is also a constant.

Of the acceleration is zero, then

1/m =(1/F)*0 =0

This gives the ordered pair (a, 1/m) of )=( 0,0)
