Activity:
Make a yo-yo move
PS2.A: Each force acts on one particular object and has both strength and a direction. An object at rest typically has multiple forces acting on it, but they add to give zero net force on the object. Forces that do not sum to zero can cause changes in the object’s speed or direction of motion. (Boundary: Qualitative and conceptual, but not quantitative addition of forces are used at this level.)
By the end of this lesson, the student should able to:
How can you make the yo-yo move towards you?
How can you make the y-yo move away from you?
Note: Accept all answers at this point.
