You need to drive to a grocery store that is 1.0 mi west of your house on the same street on which you live. There are five traffic lights between your house and the store, and on your trip you reach all five of them just as they change to red. While you are moving, your average speed is 20 mi/h, but you wait 1 min at each light. What is your average speed? a. 6.6 mi/h b. 7.5 mi/h c. 12.4 mi/h d. 20 mi/h e. None of the above
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.
