Consider the velocity vs. time graphs for two objects. (a) Does either object ever turn around? If so, identify the time or times. Explain briefly in either case. (Remember to review what you found in lab.) (b) Is there a time when both objects are speeding up? If so, identify the time or times. Explain briefly in either case. (c) Is the acceleration of object B positive, negative, or zero at t = 7 s? Explain briefly.
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.
