A sprinter accelerates from rest to 8.50 m/s in 1.26 s . What is her acceleration in m/s2? What is her acceleration in km/h2? A light plane must reach a speed of 38 m/s for takeoff. How long a runway is needed if the (constant) acceleration is 3.2 m/s2 ? A stone is dropped from the top of a cliff. It is seen to hit the ground below after 2.83 s . How high is the cliff?
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.
