1. (a) What is the acceleration of a car that goes from 20 to 30 m/s in 1.5 s? (b) At the same acceleration, how long will it take the car to go from 30 to 36 m/s ? 2. An airplane whose airspeed is 500 m/s covers a distance of 1000 m in 150 s. How strong was the headwind against it?
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.
