What causes a movement along the demand curve?What causes a movement along the supply curve?
As shown in above diagram, movement along the supply curve is from A to B and from A to C. When there is a movement from A to B, the price reduces from $p$ to $p_{1}$ i.e. from 15 to 10 and there is a contraction of supply from $q$ to $q_{1}$ i.e. from 150 to 100 . When there is a movement from A to $\mathrm{C}$ , the price increases from $p$ to $p_{2}$ i.e. 15 to 20 and there is an expansion of supply from $q$ to $q_{2}$ i.e. from 150 to 200 .

all right, We're doing problem number 26 which is asking what causes the movement along. Demand her what caused the movement along the supply curve. So let's drive. Here's the demand curve. And what's gonna cause you to go from here? Thio here. Well, shifted the supply curve. These are really poorly drawn. Speicher's Jeez, um, a shift of a supply curve from here to here is gonna cause a movement along the commander. Demand itself is not changing demands. This whole curve isn't changing, but the quantity demanded, uh is changing. And that's what a movement along the curve means. It's a changing quantity, demands for quantity supplied. And the only way that's gonna be changing is due to the intersection changing with supply curves of years like by 2 to 1. And the same will be true in the opposite direction. Let's show it. So here is our supply curve And how are we gonna see a shift from here to here? Well, same thing. Demand shifts, man. One to me in two. Since demand is shifting right, there's This isn't moving along. Spicher. The quantity supplied is changing, but supply itself a function. The curve is not changing. Just the quantity is changing, which indicates movement along the curve
