... An object has a weight of -750 N. What is the object’s mass? 19. Define Hook’s law and explain why Hooke’s Law has a negative sign. We saw that the force needed to expand a spring holds a directly linear proportion with the displacement of the spring. We used this information to write Hooke’s Law as ...
