Newton: egomaniac or troubled genius? – Physics World

Question

Mrs. Hankinson has a zero total external forces acting on her - she keeps moving at a constant velocity, if she is already moving.



a
Newton's First Law of Motion
b
Newton's Second Law of Motion
c
Newton's Third Law of Motion

Answer 1

The scenario described with Mrs. Hankinson, where she has zero total external forces acting on her and continues to move at a constant velocity, illustrates Newton's First Law of Motion.

This law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity unless acted upon by a net external force.

So the correct answer is:

a. Newton's First Law of Motion.
