1. Constant Velocity

2. Recap Fun With Cars

3. Terms Scalar Distance Speed Vector Displacement Velocity

4. Variables t v avg ( v ) x i x f Δ x

5. Average vs. Instantaneous Avg. – for the whole trip Instantaneous – at that instant

6. Graphing Tools: Position - Time Slope = Δy ÷ Δx (rise over run) General equation y = mx + b Slope is velocity

7. Our First Equation y = mx + b x f = vt + x i

8. Problem Solving Strategy Sketch and/or graph the motion Identify known values Identify the unknown Choose an equation Solve Does the answer make sense?
