Motion in Physics: Distance, Displacement, Speed

Learn to describe motion terms like distance, displacement, speed, velocity, and acceleration. Interpret motion graphs and understand relative motion using reference points. Discover the difference between distance and displacement with examples. Key concepts covered in this section include defining motion, reference points, and calculating displacement.

  1. CH 9 SEC 1 DESCRIBING MOTION

  2. 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

  3. 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

  4. 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

  5. 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
