A travels along a straight road. The following simplified graph below shows the car’s velocity over several time periods during 20 seconds of travel. a) What was the average velocity of the car during the 16.0 – 20.0 s time interval? Answer to two significant digits. b) What was the instantaneous velocity of the car at time = 18.0 s? Answer to two significant digits. c) Compare and explain your results from parts a and b.
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.
A travels along a straight road. The following simplified graph
below shows the car’s velocity over several time periods during
20 seconds of travel.
a) What was the average velocity of the car during the 16.0 – 20.0 s time
interval? Answer to two significant digits.
b) What was the instantaneous velocity of the car at time = 18.0 s? Answer to
two significant digits.
c) Compare and explain your results from parts a and b.
