What does Quantitative and Qualitative mean?

In the Alberta program of studies a student is often required to define things both quantitatively and qualitatively.


For example, in the Physics 20 program of studies, outcome 20–A1.1k reads:

Students will define, qualitatively and quantitatively, displacement, velocity and acceleration.




Qualitative means describing in words. For example:

Acceleration is the change in velocity over time.



Quantitative means describing in terms of numbers, symbols or math. For example:
$latex vec{a}=frac{Delta d}{Delta t}$

An object will have an acceleration of 1 m/s^2 if it accelerates from rest to 1m/s in 1 second.



Physics 20: Review Sheet Solutions

Here are the solutions to the quiz review. Feel free to post comments if you need help. These problems are slightly more difficult than the quiz questions. Take the time to understand these and you will do great on the quiz!

Download it here!

NOTE: The answers have been corrected.

I’ll update the download after school today

Note on question 5: The coefficient of friction is a negative number. Is this possible? No. What it means is that the box wasn’t moving at all!


If you need some step by step examples, try the following from your textbook:

  •  p. 158 #9
  • Example 3.1
  • Example 3.15

Hint: These are the most fundamental problems. If you can master these you will be in a good position to answer whatever I can ask.


Good luck!!

Physics 20 – Chapter 3 Summative Assignment

Newton’s 3 laws are an important part of understanding how objects interact and move. In this project you will choose one of the three projects to demonstrate your understanding of these 3 laws. You may work in small groups or individually, and will present your project to the class on the due date given.

Regardless of the option you choose, each project must meet the following requirements:


  • Contain a detailed description of each of Newton’s 3 laws
  • A real-life example, demo, or portrayal of each law.
  • Relevant formulas for mathematically describing your real-life example
  • Definition and explanation of relevant turns, including balanced and unbalanced forces
  • Relevant free body diagram and description of all forces in it.
  • Project is presented or shown before the class


Option A: Online multimedia presentation

Youtube, iMovie, stop-motion, 3D animation or similar.


Option B: Design and complete an experiment

An experiment or series of experiments to test or demo newton’s three laws. Must be pre-approved by the teacher and include a materials list.


Option C: A website

Weebly, WordPress or similar website. Most content must be original, and provide a rich user experience. Any content you do not create on your own must follow copyright laws and digital citizenship guidelines.

If you have have another idea you would like to try, ask me!


Please read through the rubric. To receive above an 80% you must create a quality project that is innovative and goes well beyond the minimal requirements.

Technical Project runs perfectly with no technical problems. Project runs adequately with minor technical problems. Project does not run satisfactorily. There are too  many technical problems to view project properly.
Spelling and Grammar Project honors all rules of spelling and/or grammar. Project adequately honors most rules of spelling and/or grammar. Project has multiple errors in spelling and/or grammar.
Screen Design Multimedia elements and content combine to deliver a high impact message with the elements and words reinforcing each other. Multimedia elements accompany content but there is little sign of mutual reinforcement. Screens are either barren and stark or confusing and cluttered making content difficult to understand.
Organization The sequence of information is logical and intuitive. Menus and paths to all information are clear and direct. The sequence of information is somewhat logical. The sequence of information and content is not logical and difficult to follow.
Creativity Project shows significant evidence of originality and inventiveness. The project shows some originality combined with a rehash of other people’s ideas, product or images. The work is a minimal collection or rehash of other people’s ideas, products or images.
