Learning Exercise


Material: Force in One Dimension
Submitted by: Christopher Borquez on Oct 19, 2009
Date Last Modified: Oct 19, 2009
Title: What do forces do?
Description: Students will interact with a simulation to learn about balanced, unbalanced, and net forces and see how they effect motion and velocity.
Type of Task: Core Activity, Group, Student-centered, Supervised
Time Required 15 min
Audience: Middle School
Prerequisites Skills: Motion, speed, velocity
Learning Objectives: Students will be able to describe how unbalanced and unbalanced forces effect motion and velocity and can be combined as a net force
Text of Learning Exercise: If you have a computer lab or laptops students can do this activity on their own. If not the focus questions can be answered as a class as you demonstrate.
Additional Information URL: http://phet.colorado.edu/simulations/sims.php?sim=Forces_in_1_Dimension
Assessment: Students should be able to answer the following focus questions: 1. If the forces are balanced is there any net force? 2. If the forces are balanced does the object move? 3. If the forces are balanced does the velocity of the object change? 4. If the forces are unbalanced is there a net force? 5.If the forces are unbalanced does the object move? 6. If the forces are unbalanced does the velocity of the object change?
