DISTANCE VS. DISPLACEMENT: The rescuers walks 20 km west, then 30 km north, then 15 km west, then 10 km north to locate the victims of the landslide. What is the rescuers TOTAL DISTANCE? What is the rescuers TOTAL DISPLACEMENT? 2. SPEED VS. VELOCITY: Man Naki holds a record of 20 s for the men’s 200-m race at the SEA games. What was his SPEED? 3.ACCELERATION: A car accelerates at a rate of 3.0 m/s². If its original speed is 8.0 m/s, how many seconds will it take the car to reach a final speed of 25.0 m/s?
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.
