The trajectory of an arrow traveling in Earth's gravity without air resistance is shown below at points a through e. The arrow has initial speed vo and is launched at angle to the horizontal. The vertical dashed lines represent equal time interval, At. (Note: g = 9.81 m/s²) y(m) Vo Ө 00 a b At point b the vertical velocity is: O Vo sin (0) + ½ g (24t)2 O Vo cos (0) + ½ g (24t)2 Vo cos (0)-g (24t) O Vo sin (0)-g (24t) e x(m)
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.
