1. A stone is thrown vertically upwards with initial velocity 24 m s-1. Calculate the (i) displacement of the stone after 4.0 s. [Answer: s = 17.5 m] (ii) velocity of the stone at 10 m above the point of launch. [Answer: v=±19.5 m s (iii) time to reach maximum height. [Answer: t = 2.45 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.
