2. The nearest grocery is 60 m, east from your house. You are walking at 1.2 m/s for 15.0 s toward the grocery when it started to rain and you ran back to your house to get an umbrella. It took you another 5.0 s to go back to your house. You start walking again at 1.2 m/s until you reach the grocery. (a) What is your average speed? (b) What is your average velocity?
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.
