Vectors – addition 1

May 6, 2023

Analytically and graphically addition of forces.

Motivation phase
Let's play

Do you remember the difference between scalars and vectors? Match the pairs and find out.

Motivation phase
Analyze the photo

During the play or work we have lots of forces that act on one object. How can we know how much total force acts on an object? Can we add forces? How?

Information phase
What if?

The previous photo showed us forces that are lined in the same direction. Analyze this photo and try to answer the question - Do the forces of the climber act in the same or in different directions? They act in different direction. How do we add those forces?

Information phase
Presentation about addition of vectors

Pay attention to the way vectors are added and what the addition of vectors depends on.

Information phase
How to add vectors

Watch the video and find out how to graphically add vectors that have different direction.

Consolidation phase
Add vectors as your experiment

Use kitchen scale and fruits. Measure each fruit, times its mass with 10 and add them analytically and graphically.

Consolidation phase
Answer the questions

Read the questions and answer them.

  1. What is the difference between vector addition and scalar addition, and how are they related?
  2. How is the addition of vectors used in physics, engineering, and other fields?
  3. What is the difference between adding vectors graphically and algebraically, and when is each method appropriate?
  4. Describe how to add different directed vectors graphically?
  5. Describe how to add different directed vectors analytically?
