Two balls are thrown from the top of the 5 m tall building. Both are thrown with initial speed of 20 m/s. Ball 1 is thrown horizontally, while ball 2 is thrown straight down. What is the difference in the speeds of the two balls when they touch the ground? a. 3.21 m/s c. 5.21 m/s b. 4.21 m/s d. 0
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.
