Sally has a very important date at eight in the evening, but she has some errands to do first. She bicycles over to the shopping center at the rate of 6 mph. The shopping center is 8 miles away. She spends an hour and a half there, stops to talk to a friend on the way home for 10 minutes, stops for a meal that takes her 45 minutes to eat, and then spends one hour and five minutes getting dressed for her date. What time did she have to start her errands in order to be ready on time for her date?
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.
