A force that is just enough to cause a small cart to pick up a large velocity will produce a negligible change in the motion of a train. This is because the train has much more mass and thus much more inertia than the cart.
How does the force required to move a small cart compare to the force required to move a train?

The force required to move a small cart is much less than the force needed to move a train. This is because a train has significantly more mass, and according to Newton’s second law (F = ma), more force is required to achieve the same acceleration.
