2 Motion in One Dimension • Displacement, velocity, speed • Acceleration • Motion with Constant Acceleration • Integration • Hk: 13, 27, 51, 59, 69, 81, 83, 103.
Terminology • “delta” = change • “o” = initial • “ ” = final • Position • Displacement • Speed • Velocity • Acceleration
Concepts • Slope & derivative (Giam 12-13) • Average vs instantaneous (Giam 12-13) • Integration & area under curve (Tipler) • Acceleration/force, velocity/force • Graph shapes & equations (Giam 21)
Derivative Equation • Constant acceleration (constant force) • Take derivative
Integrated Equations • Integrate “a” with time
V-squared Equation • Integrate “a” over distance “x”
Average Velocity with Uniform Acceleration Uniform Acceleration = constant valued acceleration During uniform acceleration, average velocity is halfway between vo and v: 10
Summary • Speed = rate of travel • Velocity = speed & direction • Acceleration = rate of velocity change • Motion with Constant Acceleration • Integration
Problems • Describe motion (tipler 49)
