Draw a picture with labels 2. write down everything you know and everything you want to know include units 3. If required draw a diagram (Chapter 4) 4. write down relevant equations 5. solve for the unknown 6. plug in the numbers and calculate 7. put in units and include direction Chapter 2 Important definitions position: coordinate system -known as the displacement from 0 distance: how long you have traveled - final position - initial position displacement: how far away are you from where you started Vector vs. Scalar vector contains number, units and direction scalar only contains number and units Example of vector displacement velocity Example of scalar distance mass time speed
