How do you say hello to your friends? Do you shake hands or fist bump? Do you use force to do it? Yes! But, what is force? How would you describe it?
Motivation phase
Working
Every day we work. We lift, push or put down many things during the day. If we think about the force that we use during those activities, how would we draw it? Analyze photo and describe what arrows represent. Is it force? Yes.
Information phase
Newton's laws
You have learned Newton's laws of motions. Which one is related to the force? Watch the video and find out. All of them are related to the force. Does that mean that force is important? Yes
Information phase
Vectors in general
Find out how to draw a force.

Video about vectors
To improve your knowledge of vectors please watch the following video on YouTube.
Consolidation phase
Practical example
1. Graphically draw force that is:
F=500N
F=3kN
F=70N
F=1000N
As a reminder, analyze photo.
Consolidation phase
Time to play
Try to find matching pairs.
Consolidation phase
Time to do experiment
Take the kitchen scale and some fruit. Add all fruit on the kitchen scale. Now, draw the fruit as forces. They all have same direction. Each force would be mass of the fruit times 10 N (newton).
