Extra Credit 6

In this exercise you will verify Hooke's law for a real spring and determine the spring constant of the spring.  You also will explore a spring simulation.

Go to Canvas, Assignments, Extra Credit 6 and answer the questions in blue font.

Part 1

imageOne end of a spring is attached to a rigid support.
Different weights are hung on the other end, and the spring stretches to different lengths.

 

Procedure:

position (m) force (N)
0.22 0.1
0.255 0.2

Explore the interface!

Experiment:

There are three unlabeled masses colored red, gold, and green.  Design an experiment to determine those masses.  What is the mass (in g) of the golden mass?

Move the setup to the surface of Planet X.  Given g = 9.8 m/s2 near the surface of Earth, design an experiment to determine those gravitational acceleration g' near the surface of planet X.  What is g' in units of m/s2?
