Lesson 1: Distance, Position and Displacement

• Kinematics - The study of motion
• Motion - Change in location of an object as observed by a viewer
• Distance - Length of the path travelled by an object in motion
• Direction - The line an object moves along from a starting point
• Reference Point - Point you look at for directions and distances
• Scalar Quantity - Only has Magnitude (size) (increasing values)
• Vector Quantity - Has both Magnitude and Direction
• Position - Distance & Direction of an object from a reference point. A vector quantity

  ->d (arrow symbol)
• Displacement - Change in the position of an object ->△d (triangle symbol)
• Calculating Displacement: Point A --> B (1 change)

  $->△d =$$->dfinal - ->d inital$
• Calculating Displacement: Point A --> B --. C (Multiple changes)$->△dT=$$->△d1 +$$->△d2$
