POSITION, DISTANCE AND DISPLACEMENT PHYSICS HONORS

POSITION • Position is where something is located in relation to an origin. •

POSITION • Position is where something is located in relation to an origin. • Denoted by the letter x. origin

DISTANCE Describes how far something has traveled. Denoted by the letter d. If a

DISTANCE Describes how far something has traveled. Denoted by the letter d. If a racer runs around a 400 meter track 4 times how far have they traveled? 400 m x 4 = 1, 600 m

DISPLACEMENT How is displacement different than distance? Displacement is a straight line measure of

DISPLACEMENT How is displacement different than distance? Displacement is a straight line measure of how far something has moved from its original position. Denoted by the symbol delta and the letter x (∆x).

DISTANCE VS. DISPLACEMENT The blue line represents the path taken. The purple dashes are

DISTANCE VS. DISPLACEMENT The blue line represents the path taken. The purple dashes are the distance. The green dashes are the displacement. Can the displacement ever be greater than the distance?

DISPLACEMENT What about the racer? After 4 laps, what is their displacement? The runner’s

DISPLACEMENT What about the racer? After 4 laps, what is their displacement? The runner’s displacement would be 0 m, because they ended up exactly where they started.

VECTORS AND SCALARS A scalar quantity is one that only has a size (magnitude).

VECTORS AND SCALARS A scalar quantity is one that only has a size (magnitude). Examples: • There are 30 students in this class. • I drove 5 miles to school today. • The temperature is 94 degrees today. Distance is a scalar quantity.

VECTORS AND SCALARS A vector quantity has both a magnitude and a direction. Examples:

VECTORS AND SCALARS A vector quantity has both a magnitude and a direction. Examples: • I walked 3 blocks east. • School is 5 miles north of my house. • He pushed upwards with 10 pounds of force. Displacement is a vector quantity.
