A cheetah was observed traveling a distance (d) of 100.0 + 0.2 m in a time period (At) of 2.98 0.01 s. The average speed over the time period is given by ="/Ar: The nominal value of the cheetah's speed is calculated as 33.56 /s. What is the uncertainty in the cheetah's speed expressed in /s? (Round answer to three decimal places for entry into eCampus. Do not enter units. Example: 12.341)
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.
