1. Motion Distance and Displacement Speed and Velocity AccelerationMomentum

2. Ticket In Watch the video Intro Video Intro Video Define distance in your own words draw an example of distance Define displacement in your own words Draw an example

3. Distance Distance The length of a path between two points SI Unit = Meters (m) Large Distances = Kilometers (km) Small Distances = Centimeters (cm) 1 000 m = 1 km 1 m = 100 cm Example: Rollercoaster Measure path car travels

4. Displacement Displacement The direction from the starting point AND the length of a straight line from the starting point to the ending point Used when giving directions (i.e. 15 blocks North) Example: Rollercoaster The direction from the starting point to the car And The length of the straight line from the starting point to the car NOTE: after you complete your ride and the car is back in place, the displacement is ZERO!!!

6. Vectors Vector A quantity that has magnitude and direction Magnitude = Size, length, or amount Represented by arrows on a graph or map Length of arrow = magnitude Displacement is an example of a vector

7. Combining Displacements Two displacements (represented by two vectors) SAME DIRECTION ADD MAGNITUDE Two displacements (represented by two vectors) OPPOSITE DIRECTION SUBTRACT MAGNITUDE
