1. A tennis ball is thrown upwards from the edge of a cliff with a speed of 10 m/s. It lands on the ground below the cliff 3.0 seconds later. We can ignore air resistance. What is the displacement of the tennis ball? 2. A ball is dropped over the edge of a building. How fast is the ball moving 2.0 seconds after being dropped?
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.
