Vectors V. Scalars A Vector is a quantity that is fully described by both magnitude and direction. A scalar is a quantity that is fully described by magnitude alone.
Distance Is a scalar!
Distance Is a scalar Distance is the measured separation from an object’s initial position following the same path to its end position.
Distance Is a scalar Distance is the measured separation from an object’s initial position following the same path to its end position. Only Additive!!!
Sammy pulled out of Boomland in Charleston, MO and travel East on I-57 In 15 minutes he was pulled over for speeding he had gone 18 miles. What is Sammy’s distance traveled?
Sammy pulled out of Boomland in Charleston, MO and travel East on I-57 In 15 minutes he was pulled over for speeding he had gone 18 miles. After, Sammy got his warning he continued his trip and drove 40 miles before he realized he left his phone at Boomland. What is Sammy’s distance traveled?

Displacement Is a Vector
Displacement Is a Vector While distance follows the path of travel Displacement is a measure of the distance between beginning Point A and ending Point B in a straight line.
Displacement Is a Vector While distance follows the path of travel Displacement is a measure of the distance between beginning Point A and ending Point B in a straight line. Can add and subtract depending on direction

What is Sammy’s total displacement? Do we always travel in a straight line though?

Non Linear Motion
What do we do? ?
Motion What we have learned!! Motion is a change in position relative to a frame of reference
Motion What we have learned!! Motion is a change in position relative to a frame of reference We can measure a change position by finding or calculating
Motion What we have learned!! Motion is a change in position relative to a frame of reference We can measure a change position by finding or calculating Distance- measure the path
Motion What we have learned!! Motion is a change in position relative to a frame of reference We can measure a change position by finding or calculating Distance- measure the path Displacement- measure from point A to point B
Motion What we have learned!! Motion is a change in position relative to a frame of reference We can measure a change position by finding or calculating Distance- measure the path Displacement- measure from point A to point B So now we have to measure motion relative to time!!!
