7. A car traveling at 15 m/s in the positive direction, slams on the brakes to avoid an accident and undergoes a constant acceleration. The car skids 25 m before stopping. a. Draw a velocity graph for this situation. Remember to quantitatively label your axes. (Hint: Draw the shape of the graph first, and use it to find the time it takes to stop to label the time axis.)
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.
