- PhySP19-4.1.34 Here the bleck arrows are being influenced by the green arrow. If fact, you can say that the black arrows are immersed in a green arrow field. We call the green arrow a “field vector”
-
- PhySP19-4.1.35 Here the green influencer is making the black arrow get smaller and smaller because it is in the opposite direction as the black arrow. It doesn’t turn it around instantaneously because the object that is involved with the black arrow (in this case the tennis ball) has mass. So it has INERTIA (resistance to change) The more mass the longer it is going to resist the green arrow, but the green arrow is IMMEDIATELY going to eat away at the black arrow and “slow it down”.
-
- PhySP19-4.1.36 If I line up the black arrows through time, their tips connect in a straight line. (the v vs. t in a trio)
-
- PhySP19-4.1.37 If I line up the accumulation of position over time the tips of the arrows form a parabola because the green arrow influences the black arrow which combines to influence the position. So it is influence squared (parabola).
-
- PhySP19-4.1.39 THis is getting a little ahead, but if the green influencer arrow is perpendicular to the black arrow it influences it to get longer in a direction perpendicular to its original direction.
-
- PhySP19-4.1.40 The green arrow does NOT influence the black arrow in its original direction so the black arrow will keep that original direction forever (Newton’s 1st Law)
-
- PhySP19-4.1.38 The next black arrow will still have that same component in its original direction, but now it will start to have a component in the direction of the green influencer. It will never totally go in the direction of the green arrow because it can not shake the influence its original momentum (moving inertia). Not in a million years of movement (or until it reaches the speed of light in the green direction.
