DO NOW
• What is a frame of reference and relative motion?
Frame of Reference
• In order to describe motion a frame of reference is needed
• A frame of reference is a system of objects that are not moving with respect to one another.
• How fast something is moving is dependent on the frame of reference
• Relative motion is movement in relation to a frame of reference
Distance
• Distance is the length of the path between two points.
• The SI unit is meters and large distances use kilometers
Displacement
• Is the direction from the starting point and the length of a straight line from the starting point to the end point.
• It is good to use displacements for directions• You may need to combine displacements
which can be done using vector addition since displacement is an example of a vector.
Combining Displacements Along A Straight Line
• If in the same direction you add them • If in opposite directions you subtract them
Displacement Not Along A Straight Line
• When the vectors have different directions they may be combined by graphing.
• The straight line from the start to the end point is called the resultant vector and that is the displacement.
Recap
• Displacement is….. • Direction from the starting point and the
length of a straight line from the starting point to the ending point
• Distance is…… • The length of the path between two points.
