Since F = ma and the same force acts, the force is constant for every mass. Checking the graph, a × m is the same at each point (for example 1 kg × 10 m s −2 = 10 N, 2 kg × 5 m s −2 = 10 N), so F = 10 N throughout.
The force-mass graph is therefore a straight horizontal line at F = 10 N , parallel to the mass axis.
