Question

Which of the following best illustrates an application of Newton’s First Law (also called the Law of Inertia)? A A passenger not wearing a seatbelt is ejected from an automobile during a severe crash. B Dinner plates remain on a table when a slick tablecloth is pulled out from underneath them. C An ice hockey puck continues sliding across the relatively frictionless ice until it comes into contact with a wall or a player’s stick. D All of these are examples of Newton's First Law.

Answer 1

Answer:

D. All of the Above

Explanation: Newton’s first law is “An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force” So if a pencil is rolling on a table and you stop it with you hand instead of letting it roll of the table in this case, the pencil is the object in motion and you are the unbalanced force.
