Images below represents a plot. The horizontal axis on each plot represents time. The vertical axis represents whichever quantity (position, velocity, acceleration) is being discussed. The origin of each plot is represented by 0, and the function is represented by the colored line. For each of the statements at the bottom select the image that best represents the requested plot. You may use the same image for multiple statements if it is appropriate. "K A ck of t E = " AA car starts from rest at a stoplight and undergoes constant acceleration to the East. Which graph best represents the velocity of the car as a function of time? (Choose East to be the positive direction.) HYou hold your arm out over a cliff and release a ball from rest. Consider the time from just after the ball leaves your hand to just before it hits the ground. Which graph best represents the position of the ball as a function of time? (Choose up to be the positive direction and choose the point the ball is released as the origin.) FA bicycle is driving West at a constant velocity. Which graph best represents the velocity of the bicycle as a function of time? (Choose East to be the positive direction.) B You hold your arm out over a cliff and release a rock from rest. Consider the time from just after the rock leaves your hand to just before it hits the ground. Which graph best represents the acceleration of the rock as a function of time? (Choose up to be the positive direction.) Submit Answer Incorrect. Tries 3/10 Previous Tries This discussion is closed. Send Feedback
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.
