Physical Science:
Net Force and Vectors-
Will was quizzed on momentum and forces. I showed him situations where force, of different strengths and directions, was applied to an object, and asked him to determine how much force was being applied and what affect this force had on the object. I explained that this ultimate quantity of force is called the net force, and the arrows were called vectors. We worked a few examples so he was confident with the term. I then used an object with two strings attached. I let the object hang from the strings, and had Will identify if one string was exerting more force than the other. I then explained how to draw a parallelogram to show with vectors the force of the two strings.
