Choose the best example of uniform motion. A pen falls slowly at first but gains speed the longer it falls towards the ground OA toy car pulled by a child rolls 5 inches for every second the child moves it A ball thrown up in the air begins fast, comes to a stop, and falls quickly again. O A bottle of juice left on a hill rolls slowly down the hill until it's too fast to be caught
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.
