The velocity against time graph below shows the motion of two cars A and B. velocity/m s¹ 8 co 6.5 C D B 9 tis Which of the following statements correctly describes the motion of both cars? A Cars A and B meet each other at 0s and 6.5 s respectively. B Initially, car B is faster than car A. After 7 s, B stops moving while A continues to move on. Initially car B is leading. After 6.5 s, car A is leading. Throughout the 9 s interval, car B is leading. (
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.
