Terms Scalar Vector Displacement Velocity • Distance • Speed
Variables • t • v • x0 • x • Δx
Graphing Tools: Position - Time • Slope = Δy ÷ Δx (rise over run) • General equation y = mx + b • Slope is velocity
Our First Equation • y = mx + b • x= vt + x0
Problem Solving Strategy • Sketch and/or graph the motion • Identify known values • Identify the unknown • Choose an equation • Solve • Does the answer make sense?
