A large boulder would have the greatest tendency to stay motionless. This is due to its significant mass and inertia, which make it more resistant to changes in its state of motion compared to smaller objects like a piece of dust, sand, or a small rock. The larger mass means it requires a greater force to move it, making it more likely to remain stationary in the absence of such force.
