A student on her way to school walks East in a straight line 24 meters towards the bus stop, but realizes she dropped her physics notebook along the way. She turns around to retrace her steps. She walks 15 meters West before finding it and then runs the remaining 40 meters East to the bus stop. Assume her home is the reference point. - What is her total distance traveled? (m) - What is her total displacement? ___m to the a. west, b. east, c. no direction, d. north, e. south
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
a. A student on her way to school walks East in a straight line 24 meters towards the bus stop, but realizes she dropped her physics notebook along the way. She turns around to retrace her steps. She walks 15 meters West before finding it and then runs the remaining 40 meters East to the bus stop. Assume her home is the reference point.

- What is her total displacement? ___m to the a. west, b. east, c. no direction, d. north, e. south
b. An ant is crawling along a yardstick that is pointed with the 0-inch mark to the east and the 36-inch mark to the west. It starts at the 8-inch mark, crawls to the 21-inch mark, then moves to the 18-inch mark.
-What was the total distance the ant traveled? (in)
-What was the total displacement of the ant? _____in to the a. west, b. east, c. no direction
