A car is standing 200 m behind a bus, which is also at rest. The two start moving at the same instant but with differ- ent forward accelerations. The bus has acceleration 2 m/s? and the car has acceleration 4 m/s?. The car will catch up with the bus after a time of: (a) Vī10s (b) V120s (c) 10/2s (d) 15 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.
