Problem 2: You are driving in a car with your friend, who is speeding around the corner of a highway. You are worried for your safety, so you ask your friend how fast they are going. Your friend responds, "I am going around this corner at a constant velocity of 65 mph." Is their statement physically correct? No, cars always slow down as they go around corners. No, the word "velocity" is being used incorrectly. OIt might make sense, depending on extra information which is not being given in the problem? Yes, this statement is acceptable.
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.
