1. Find the time it takes to travel 30 km for a bus which accelerates uniformly from 40 km/hr to 80 km/hr. 2. Find the distance travelled by a scooter in 25 minutes it accelerates from 100 m/s to 150 m/s. 3. A man is running along a straight road at 4 m/s. If he accelerates at 0.2 m/s in 0.5 minutes, what is his new velocity?
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.
