Error Estimation and Using Excel |
Paper and pencil activities for sig figs, % errors, propagation of error, Excel formulas & plotting. |
|
|
Introduction to Statistical Uncertainty |
Discuss avg, stdev, and Standard Error associated with multiple groups each getting avg & sigma. Apply knowledge to golf ball drop & ping pong ball drop. |
|
|
Math Modeling of1D Motion |
|
Do first task on screen together as a class. Then require 2 tasks with questions or 4 tasks without questions.
The first 2 pages of 161handouts.pdf are step-by-step instructions for making scatter plots (with screen shots). |
|
Freefall with spark timer |
|
|
|
Vectors with Force Tables |
|
|
|
Projectiles |
Contains several variations in handout. Be sure you know which variation you want them to do... |
|
|
Newton’s 2nd Law Part 1 (Fletcher’s Trolley) |
This one uses a Fletcher’s trolley and stopwatches. |
|
|
Newton’s 2nd Law Part 2 (angled) |
This one uses an angled Fletcher’s trolley and photogates. |
|
|
Static Friction Only |
3 experiments use hockey puck on incline to compute mu_s |
|
|
Kinetic Friction Only |
3 experiments use hockey puck on incline to compute mu_k |
|
|
Static and Kinetic Friction Together |
2 experiments measuring mu_s, 1 measuring mu_k all use hockey puck on incline |
|
|
Circular motion (swinging stopper) |
Practice to get the technique right...especially practice how to stop the thing without getting hit in the face. Definitely wear eye protection for this one. |
|
|
Work and Energy |
1. simple pendulum at angle...get v_bot 2. interrupted pendulum...get largest circle radius 3. Atwood’s with spring...get k Focus on getting data & simplest error analysis (avg & stdev type stuff). |
|

Inelastic collisions |
|
|
|
Elastic collisions |
|

|
Old Rotation Lab |
For various shapes: rotation2.0.xlsx For variable point masses: rotation2.0c |
Still a decent lab. Get I of turntable then choose to add disk, ring, and rod (with point masses) or rod with variable position point masses. |
|
Torque & Rotational Energy |
Students do Atwood’s machine with massive pulley using multiple radii and swinging rod with point mass. Worked example for use before task 1 (~30 min). Worked example for use before task 2 (~30 min). |
|
|
Angular momentum (collision with rotation) |
Drop objects onto spinning disk. |
|
|
Buoyant Force |
Lower aluminum cylinder into beaker while recording forces using Pasco Force Sensor. |

Let’s Code Physics YouTube Channel |
Great series of vids if you are just getting started. First 10 vids or so are pretty darn useful. |

|
Vector Decomposition & Addition with Python |
Requires use of glowscript.org Free but requires google ID. Instructions to get started in glowscript included in handout. |
Copy a code which draws a coordinate system & single vector decomposed into components. The components are shown added tail-to-tip with the resultant being the initial vector. Modify the code to display graphical addition of three 3D vectors and associated resultant. |
|
Making Your First Simulations With Motion |
|
Make your first animation using a while loop. Contains a long code filled with “bells & whistles” such as waiting for a click to run, making a plot, creating titles & captions, etc. |
|
Projectile Simulation (with & without drag) |
|
Copy my code without drag. Read how to add in drag. Make the appropriate code modifications. Use the tricks from the last page of 161FirstMotionSims.pdf to make a final code that outputs potentially useful data. |
|
Simulate Blocks on Plane with Friction and Hanging Mass |
The following variation on this handout (including some FBDs) may be useful. SimBlockInclineFriction |
Code provided for a single block on plane with friction. Code fragment for creating the objects for adding in a hanging mass (but none of the physics coding).
Discuss the pseudo code with students so they can think through the if/else conditionals... |
|
Estimate & visualize center of mass positions for various 1D, 2D, & 3D shapes |
Training Playlist (~1hr total)
|
Code provided for uniform rod. Fragments to modify for non-uniform rod. Code for triangular plate. Fragments or almost nothing for semi-circular plate, frustum, hemisphere, and arc. Students really struggle...be ready. |
|
Rotational Kinematics & Rod Pendulum Visualizations |
First make a rotating rod. Then add in a point mass on the rod. Draw velocity arrow for point mass. If torque has been covered, also add in simulation of a uniform rod pendulum. |
|
|
Static Equilibrium Visualization |
|
Do a static equilibrium problem analytically then try visualize the forces. In theory you can work up to making a plot of tension versus cable location. |
|
Universal Gravitation Visualizations |
|
Code provided for two fixed points masses and compute/draw force arrows. Students modify to add a third fixed point mass. Next code provided animates one of the point masses. Students modify to animate the other one. Students modify code to analyze orbits and escape velocity. |
