Copy of 11.) Forces Simulation (5/28/2026)

Directions:

1. Click, "Net Force" in the simulation below.

2. In the menu at the top of the simulation, check the boxes for “Sum of Forces”, “Values”, and “Speed”.

3. Answer the below questions.

In the simulation:

• Place one small blue person on the left side - it must be small.

• Answer the questions below the simulation.

In the above simulation, click "Net Force".

In the menu to the upper-right, click, "Sum of Forces," "Values," and "Speed."

On the rope:

• Left side - place one small blue person - it must be small.

• Right side - place one medium red person - it must be medium.

Click on the “Friction” section of the simulator.

• In the menu in the upper-right, select, "Forces," "Sum of Forces," "Values," "Masses," and "Speed."

• Apply the variables to the simulation as described in each row of the below table.

• As the simulation runs for each set of variables, observe for and record the friction force and sum of forces in the table.

• To run the simulation, slide the "Applied Forces" control all the way to the right, up to 500 N.
