Explanation:

Question 4

The sentence describes the tendency of objects to resist changes in motion. The word from the word bank that fits this description is "inertia", as inertia is defined as the resistance of any physical object to any change in its velocity.

The sentence states the rule "an object in motion stays in motion unless acted upon by an unbalanced force", which is Newton's 1st Law of Motion. So the word from the word bank that fits here is "Newton's 1st Law".

The sentence describes a push or a pull on an object, and the word from the word bank that means a push or pull is "forces".

Answer:

inertia
