  1. Chapter 2: Kinematics in One Dimension Essential Concepts and Summary

  2. Displacement • Displacement is a vector pointing from an objects' initial position to its final position, and has a magnitude equal to the shortest distance between the points • SI Unit: meter

  3. Speed and Velocity • Average velocity is the change in displacement over change in time. • Average speed is change in distance over change in time. • Velocity has direction, speed doesn't

  4. Acceleration • Average acceleration is the change in velocity over a change in time

  5. Kinematics for Constant Acceleration • These set of four equations apply when an object moves with constant acceleration along a straight line

  6. Derivation

  7. Freely Falling Bodies • Idealized motion, where air resistance is neglected and acceleration is nearly constant, is referred to as free-fall. • Acceleration due to gravity on earth, g, is 9.80 m/s2 • Kinematics equations are the same but a = g

  8. Graphical Analysis • Slope of position vs. time plot is velocity • Slope of velocity vs. time plot is acceleration • The area underneath a velocity vs. time plot is distance

  9. Summary of Equations
