How did you learn these ideas?
-discussing class
-watching videos
-doing experiments

Why is it important to know these ideas(What real-world application is there)?

What science ideas did you learn?
-force diagrams
-unbalanced force
-The direction of unbalanced force, on a force diagram, and the direction of delta v ,on a motion diagram, are in the same direction.-Newton's First Law
-balanced forces equal 0

How did you learn these ideas?
-by experimenting in class
-discussing
-doing homework
-watching videos
-drawing representations on white boards

Why is it important to know these ideas(What real world application is there)?
-It is important because then we can use it to draw other diagrams and use it to explain why certain things happen.
-A real world example is 2 little kids pulling from opposite directions on a toy.
