Michael, the regional manager of a mid-sized paper company in northeastern Pennsylvania, must drive to The Office every day for work. During his morning commute, he drives an average of 25 mph due East for 15 minutes to exit his neighborhood, then turns 45o N of E onto I-81, where he drives at 70 mph for 5 more minutes. Finally, he exits I-81 and drives at 30 mph at 45o S of E for 5 minutes before pulling into Scranton Business Park at 1725 Slough Avenue. a. What is his total distance traveled? b. What is his average speed? c. What is his displacement from home when he arrives at work? d. What is his 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.
