Pre Lab
Directions/Description: In this lab we will be exploring what is happening when nothing is happening. In other words, we will explore sets of forces that add to zero. In these cases we have what is called a static equilibrium.
For any object that is not moving (or moving with a constant velocity), all of the forces acting on it must add to zero according to Newton’s first law. Net forces cause acceleration. Similarly, net torque causes rotational acceleration. Torque is the rotational equivalent to force. We will explore torque in this week's simulation. Static equilibrium means that all forces and torques on a stationary object/system add to zero. Static = Not Moving Equilibrium = All forces and torques add to zero In lab this week, we will create and analyze cases of static equilibrium like in the sample problem to the right. Prior to this week's lab be sure to 1) Watch the two videos to the right, 2) Watch my Pre Lab video below, 3) Explore the simulation as described in the video, and 4) Complete the pre-lab quiz on Blackboard. |

Simulations
Explore the Balancing Act simulation embedded at the following link to see how different factors impact torques and equilibria.

You may use the simulation to answer the pre lab quiz questions as well.

Lab
This week you will be completing a static equilibrium lab not found your lab manual. It will be provided for you at the beginning of the lab period.
We will be using meter sticks and hanging masses to create scenarios demonstrating static equilibrium..
