FLASHCARD QUESTION
Front
What is Newton's 1st Law of Motion?
Back
Newton's 1st Law states that an object at rest will remain at rest, and an object in motion will continue to move at a constant velocity unless acted upon by an unbalanced force.

FLASHCARD QUESTION
Front
What is Newton's 2nd Law of Motion?
Back
Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, expressed as F=ma.
