Displacement


Kinematics
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
Relative Motion

  • Frame of Reference

  • Earth

  • Newton Example page 14

  • Chair Example


Distance
Distance

  • Scalar Quantity

  • Units: m

  • Total “area” covered


Displacement
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.

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
