Concept explainers

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.

Constant Acceleration Problems Show all steps and work! A cyclist is traveling at 12.0 m/s when he applies the brakes and begins to slow. After 4.5 s the cyclist has slowed to 3.0 m/s. What was the cyclistť's (a) acceleration (assume it was constant)?, and (b) the distance traveled in this time? 1. A truck driver travels at 90.0 km/h down a highway when he sees a deer cross in front of him down the road. He hits the brakes with a reaction time of 0.750 s and begins to slow down (at a constant rate) of 5.50 m/s². Reacting to the horn, the deer yielded and the truck driver was able to disengage the brake- his speed at that time was 45.0 km/h. a) How far from the moment he saw the deer to when the brakes were disengaged did the 2. truck travel? b) How long was the truck braking? 3.
