You want to model Newton's first law of motion using a sliding object. Which surface would work best?

Answer 1

In order to model Newton's first law of motion accurately, it is preferable to choose a surface with minimal friction or resistance. A surface that works best for this purpose is a smooth, level, and slippery one. Examples would include ice, polished marble, or a low-friction material like Teflon. Choosing such a surface would minimize the effects of friction and external forces, allowing the object to slide freely and maintain constant velocity unless acted upon by an external force, as described by Newton's first law of motion.
