Introduction to Kinematics Distance & Displacement
Kinematics • Study of motion without regard to the forces which produce it. • Motion: Described in terms of position as a function of time • Caused by a force [A push or a pull] – Study of dynamics
Relative Motion • Frame of Reference • Earth • Newton Example page 14 • Chair Example
Distance • Scalar Quantity • Units: m • Total “area” covered
Displacement • Vector Quantity • Units: m • Straight path distance from start to finish (shortest path possible)
200 m East 1000 m West When school gets out you go to the grocery store which is 200 m due east. After leaving the grocery store you head home 1000 m due west. Calculate your total distance and displacement.
Distance 200 m East 1000 m West
Displacement 200 m East 1000 m West
600 m North 200 m East This time after going to the grocery store you decide to go to your friends house 600 m due north. Calculate your total distance and displacement
Distance 600 m North 200 m East
Displacement 600 m North 200 m East
