Use the graph to answer the question. Speed (km/h) 100 20 Motion of a Car N 10 30 50 70 90 Time (min) The graph shows the motion of a car. Which conclusion could be drawn from the data? A. The car was at rest between 1 and 2. B. The car was moving faster at 2 than at 1. C. The car was slowing down between 3 and 4. D. The car was constantly speeding up between 1 and 3.
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.
