The speed of light is now defined to be c = 2.99792458 × 108 m/s. (a) Express the speed of light to three significant figures. 4.03.00*10e8 X Your response is off by a multiple of ten. m/s (b) Express the speed of light to five significant figures. 4.02.9979*10e8 X Your response is off by a multiple of ten. m/s (c) Express the speed of light to seven significant figures. 4.0 2.997925*10e8 X Your response is off by a multiple of ten. m/s
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.
