many Forces Typically act on objects that are balanced or unbalanced.
[CER] DISCUSSION QUESTION:
Are the forces acting on a moving self-driving car balanced or unbalanced? Make a claim then gather evidence to support and justify your claim throughout this lesson |
/ Ii / Investigate
1. Net Force Challenge - investigate how you can tell if the forces on an object are balanced or unbalanced.
2. Tug-of-war - demonstrate balanced and unbalanced forces to determine the winner. 3. Force Memes - create your own hilarious memes demonstrating both balanced and unbalanced forces. |

Forces and Motion: Basics Guide
|
Discover and describe how balanced and unbalanced forces affects the motion of the wagon in this simulation.
/ Iii / Level Up!
During this lesson you will learn more about how you can predict an object’s motion, changes in motion, and stability.
✎Notes:
- Each force acts on one particular object and has both a strength and a direction.
- An object at rest typically has multiple forces acting on it, but they add to give zero net force on the object.
- Forces that do not sum to zero can cause changes in the object’s speed or direction of motion.
- The patterns of an object’s motion in various situations can be observed and measured; when past motion exhibits a regular pattern, future motion can be predicted from it.
