The Bumper Cars at Accoland illustrate horizontal acceleration. Bumper cars are designed to be able to collide with no danger to the rider. That's because the cars are surrounded in large rubber bumper pads that diffuse the impact, while the driver is snuggly buckled in with a harness. Newton's' third law of motion (which states that “if one body exerts a force on a second body, the second body exerts a force equal in magnitude and opposite in direction to the first body.”) certainly applies to bumper cars. Riding in a bumper car lets the rider experience what the impact from a real car would feel like but in a safer environment. As you collide with another car you feel the inertia of your body moving forward even after the vehicle has stopped. The size and weight of the driver will affect the moment as well, as will the speed, and the type of impact front, side, and corner.
