The image shown provides the graphs of the velocity and acceleration functions that model the motion of a certain object. Use the graph to answer the following problems: Indicate whether the object is speeding up or slowing down at the following times. Include a brief justification for your response a. t = 2 The object is ______________________________ b. t = 5 The object is ______________________________ c. t = 8 The object is ______________________________ d. t = 11 The object is ____________________________ e. Is there a time when the object is stopped but the acceleration is not zero? Explain your reasoning.
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.
