7. (M) t (s) 10 Two objects C and D are moving according to graph. Which of the following is true? C has a greater velocity than D. D has a greater velocity than C. C and D have the same velocity. Cis accelerating. a. D is moving, and C is at rest. b. C is moving, and D is at rest. c. C is accelerating. d. C and D are both moving. C has a greater velocity than D. O e. C and D are both at rest. C and D have the same velocity.
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.
