Forces: Balanced and Unbalanced

Introduction

In this web quest, you will be learning about forces on an object. You will dive into how unbalanced and balanced forces effect how an object reacts. A force acts on one particular object and has both strength and a direction. We know that an object at rest, typically has multiple forces acting on it. 

Task

With a partner, you will work together to learn about balanced and unbalanced forces. As you go through this web quest, and learn about the variety of forces, you and your partner will complete the graphic organizer for this lesson. Once the graphic organizer is completed, you will be tested on your knowledge of the topic. 

After your research on forces is finsihed, I want you to come up with your own example of a balanced or unbalanced force!

Process

Balanced or Unbalanced? 

Balanced and Unbalanced Forces with 20+ Examples and Q&A

A force is exerted on one object by another. 

A Balanced force is defined as the resultant of all the forces that acts on a body or an object, and sums up to zero, without causing this body or object to move, accelerate, or change its direction, size, or shape.

An Unbalanced force is defined as the resultant of all the forces that acts on a body or an object, and is not equal to zero, while causing this body or object to move, accelerate, or change its direction, size, or shape.

 

You and your partner will watch this video on balanced and unbalanced forces. Make sure you are paying attention to the topics covered in the video because it will help you answer questions later on!

We know that a force can either be balanced or unbalanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged. When the forces acting on an object are unbalanced, they do not cancel out one another.

Look at this picture. On the top, we see that there is the same amount of people on each side pulling the rope equally. This is an example of a Balanced force. On the bottom, it is the opposite. There is no an equal number of people on each side, and the force is not equal. This is an Unbalanced force.

Evaluation

Once you have completed the Google form quiz, you will bring me your graphic organizer on Balanced and Unbalanced forces. After everything is turned in, you will return to your desk and draw your own example of a balanced or unbalanced force. We will present our drawings tomorrow in class. 

Conclusion

You have commpleted today's assignment! We have learned so much about forces and how they can be balanced or unbalanced.

Teacher Page

In this lesson, the students will be investigating balanced and unbalanced forces. They will work in pairs to identify what makes a forced balanced or unbalanced. The students will learn that strength and direction play a major role in the force on an object. 

 

Standard

3 - PS2 - 1 Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.

Clarification Statement

Examples could include an unbalanced force on one side of an object that can make it start moving, or balanced forces pushing on an object from opposite sides will not produce any motion at all. Investigations include one variable at a time: number, size, or direction of forces.

Disciplinary Core Ideas

Each force acts on one particular object and has both 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. (UE.PS2A.a)
