### 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.

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
