A researcher is calibrating a physical simulation of a delivery chute by measuring the acceleration of a package sliding down a wooden plank under a known towing force.
Before attaching the towing line and recording any data, the researcher elevates one end of the plank slightly to create a small incline.
Give one reason why the plank is tilted.
