A man walks 20.0km South and then 8.00km 35.0oN of W. a) What is the man’s displacement ? (16.7km, 67o S of W) b) What is the man’s average speed if the entire trip takes 12.0 hours ? (2.30km/hr) c) What is the man’s average velocity ? (1.40km/hr, 67o S of W)
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.
