What are some examples of force diagrams


Activity overview

The force can be calculated using Newton's 2nd law, force = mass x acceleration or F = ma , be calculated. That is, when there is a resultant force, the speed changes. In this task draw the student Force diagrams of a car moving in three different ways . The car drives at a constant speed (balanced), accelerates and brakes. Students should be reminded to pay attention to the direction and length of the arrows and to use consistent color coding and lettering on all diagrams.

To differentiate this and challenge your advanced students, imagine a scenario where the car is on a slope. That way, students don't just look at vertical or horizontal forces.

Instructions for students

Show your understanding of force and how it affects movement by drawing force graphs. Remember that forces have both magnitude and direction. This means that you need to pay attention to the direction and length of the arrows.

  1. Click on "Start Assignment".
  2. The situations on the left are Driving a car at a constant speed , Accelerate car and Car slower .
  3. Use the arrows from the Shape menu to add force graphs to the cells on the right. Modify the arrow so they are the correct length and point in the correct direction.
  4. Label your arrows with textables.
  5. Save and submit your storyboard.

    Data protection and security

    Each version of Storyboard That has a different privacy and security model tailored to the expected usage.

    Free version

    All storyboards are public and can be viewed and copied by anyone. They'll also show up in Google search results.

    Personal edition

    The author can choose to keep the storyboard public or mark it as not listed. Storyboards that are not listed can be shared via a link, but otherwise remain hidden.

    Educational edition

    All storyboards and images are private and secure. Teachers can view all of their students' storyboards, but students can only see their own. Nobody can see anything. Teachers can lower security if they want to allow sharing.

    Business edition

    All storyboards are private and secure for the portal and use enterprise-class file security hosted by Microsoft Azure. Within the portal, all users can view and copy all storyboards. In addition, any storyboard can be "shared", whereby a private link to the storyboard can be released externally.
