How to represent this statement in a diagram?

In summary, the conversation was about the representation of two forces with magnitudes of 3N and 5N and an angle of 60 degrees between them. The first diagram did not have arrowheads, causing confusion about the direction of the forces. The speaker then made changes to the diagrams, but it was pointed out that the top diagram was incorrect as it showed an angle of 120 degrees instead of 60 degrees. The person responsible for the diagrams admitted their mistake and it was concluded that the bottom diagram was correct. The conversation ended with the agreement to explain the mistake to the person responsible for the diagrams.

How to represent this statement in a diagram?
Statement: My friend represented this sentence "Two forces have magnitude of 3N and 5N, and have an angle of 60 between them" into this diagram:

243220


But why didn't he represent like this?:
243221

Hi,

You can't tell until you add arrowheads. If A and B both point to the left in the first diagram (or both to the right), the angle is indeed 60 degrees.
And if e.g. A points to the left and B to the right, then the smallest angle to rotate A to make it align with B is 120 degrees.

Hi, You can't ...rees.

See, I made changes to my diagrams.

Yes, now my #2 post looks weird...

Never mind. The smallest angle you can rotate over to make them align and pointing in the same direction is 120 degrees in the top picture and 60 in the lower.

So both diagrams are fits the context ?

No. In the top diagram the angle between the two vectors is 120 degrees, not 60.

Are you saying second diagram is correct ?

What I say isn't important; what you understand is

In the bottom diagram the angle between the two vectors is 60 degrees

The short answer is: Because he was wrong.

@Benjamin_harsh : it it clear to you now, and can you explain (e.g to your friend) why he was wrong ?

FAQ: How to represent this statement in a diagram?

How do I determine what type of diagram to use?

The type of diagram to use depends on the type of information you want to represent and the specific relationships between the components within the statement. Some common types of diagrams include Venn diagrams, flowcharts, and concept maps.

What elements should I include in the diagram?

The key elements to include in a diagram are the main components of the statement, their relationships, and any relevant supporting information. It's important to only include essential information to avoid clutter and confusion.

How can I ensure the diagram accurately represents the statement?

To ensure accuracy, start by thoroughly understanding the statement and its components. Then, carefully consider the relationships between the components and use appropriate symbols or labels to represent them in the diagram. It can also be helpful to have others review the diagram for accuracy.

Can I use different colors or shapes in the diagram?

Yes, using different colors or shapes can be helpful in visually differentiating between components or indicating specific relationships. However, it's important to use them consistently and purposefully, rather than just for aesthetic purposes.

Is there a specific format or layout I should follow for the diagram?

There is no one specific format or layout that must be followed for a diagram. However, it's important to choose a layout that makes the most sense for the statement being represented and ensures clarity for the reader. Some common layout options include hierarchical, radial, or network diagrams.
