1. A cart is being pulled along a horizontal track by an external force (a weight hanging over the table edge) and accelerating. It shoots a ball straight up (vertically) out of a spring launcher as it moves. (The ball has a very small mass in relation to the cart). After it is fired, what happens to the BALL? 1) it depends on how fast the cart is moving 2) it falls behind the cart 3) it falls in front of the cart 4) it falls right back into the cart 2. The same cart is now rolling down a smooth inclined track and accelerating. It shoots a ball straight up (vertically) out of a spring launcher as it moves. After it is fired, what happens to the BALL? 1) it depends on how fast the cart is moving 2) it falls behind the cart 3) it falls in front of the cart 4) it falls right back into the cart

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.
