How does changing only the load change acceleration at the same net force?

Mapping under review · 2026-10-21A rover needs to move a heavier cargo using the same motor. Design a fair comparison: record two runs with different masses, holding applied force, friction and elapsed time fixed. Then predict a new load.
Fₙₑₜ = applied force − opposing friction; a = Fₙₑₜ ÷ mass. If the applied force does not exceed the threshold, friction balances it and the initially resting cargo stays at rest. The track view clips at 200 m; the numerical position stays exact.

What do these two runs support about changing mass at the same nonzero net force?
A fresh run uses 3 kg, an applied force of 16 N and the same 2 N friction threshold. Starting from rest, what is its acceleration? Subtract the opposing force before dividing by mass.
Original one-direction constant-force model, initially at rest. Vertical forces balance. Friction balances an applied force up to the selected threshold, then remains at that threshold while sliding. The threshold is an independently chosen force, not a material coefficient; changing mass does not automatically change it. Real static and kinetic friction can differ. No collisions, air resistance, slope or motor power limit are represented. Graph and table provide alternatives to the track picture; motion advances only when requested.
