CH 9 SEC 1 DESCRIBING MOTION
GOAL/PURPOSE • IN THIS SECTION STUDENTS LEARN HOW TO DESCRIBE MOTION USING TERMS DISTANCE, DISPLACEMENT, • SPEED, VELOCITY, AND ACCELERATION. • YOU WILL ALSO LEARN HOW TO INTERPRET GRAPH OF MOTION
MOTION • KEY- AN OBJECT IS IN MOTIONIF ITS DISTANCE FROM ANOTHER OBJECT IS CHANGING. • REFERENCE POINT- IS PLACE OR OBJECT USED FOR COMPARISON TO DETERMINE IF SOMETHING IS MOVING. • KEY- AN OBJECT IS IN MOTION IF IT CHANGES POSITION RELATIVE TO A REFERENCE POINT
Relative motion • KEY- DEPENDS ON YOUR REFERENCE POINT. SITTING IN CHAIR NOT MOVING BUT IF YOU USE THE SUN AS A REFERENCE POINT YOU ARE MOVING. • DISTANCE- IS THE LENGTH OF A PATH BETWEEN 2 POINTS. • EX- WALKING HOME FROM SCHOOL • DISPLACEMENT- IS THE LENGTH AND DIRECTION THAT AN OBJECT HAS MOVED FROM ITS STARTING POINT • EX- AS THE CROW FLIES???? THE STRAIGHT LINE
KEY- distance is the total length of the actual path between 2 points. Displacement is the length and direction of a straight line between starting and ending points
