In a total time of 3.0 minutes, a duck on a pond paddles 31 m [N33oE] and then paddles another 57 m [E28oS]. Solve for the displacement graphically (with a ruler and protractor) and then answer the questions. Using the displacement you determined from your graph, what was the duck’s average velocity for the trip? What total distance did the duck travel? What was the average speed of the duck for the whole trip?
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.
