Vectors in general
Vectors as visually representing the force.
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?
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.
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
Find out how to draw a force.
To improve your knowledge of vectors please watch the following video on YouTube.
1. Graphically draw force that is:
F=500N
F=3kN
F=70N
F=1000N
As a reminder, analyze photo.
Try to find matching pairs.
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).
