STEPS

Use the following guide to complete the following steps.

1. Observe and note the mass of Mass 1 and Mass 2.
2. Observe and note the distance between m1 and m2.
3. Observe and note the Force on m1 by m2 and the Force on m2 by m1.
4. Change the distance between m1 and m2 by moving the masses apart. Observe and note the Force on m1 by m2 and the Force on m2 by m1at two new distances apart. Note: You will move the masses by placing your mouse on the figures and sliding them.
5. Change the mass of Mass 2. Note: You will change the mass by moving the slider to the left or right. Observe and note the Force on m1 by m2 and the Force on m2 by m1when Mass 2 has two different masses.

1. How well did you describe what was done during the simulation?
2. How well did you describe what was observed during the simulation?
3. Did you provide additional questions about gravitational forces?
4. Did you discuss two specific ideas from the reading related to the observations?
5. Did you discuss how the simulation contributed to your understanding of the theory of gravitation and its historical development?
