a cheetah and a gazelle are both stopped. The gazelle runs and accelerates so that it reaches a velocity of 20 m/s after 100m, then runs at a constant velocity of 20 m/s. The cheetah waits 3 seconds and accelerates at 2.5 m/s to reach a final velocity of 22 m/s and then travels down the road at 22 m/s. When does the cheetah catch the gazelle? How far do they travel?
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.
