A bobsled has a constant acceleration of 2.0 m/s2 [E], starting from rest. a) How fast is it going after 5.0 s? [speed] b) How far has it travelled in 5.0 s? [distance] c) What is the average velocity in the first 5.0 s? [velocity] d) How far has it travelled by the time its speed has reached 30 m/s? [displacement, incl. direction]
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.
