1.A train moves with a constant velocity of 25 m/s. The train conductor at the front of the train begins to walk towards the back of the train with a velocity of 4.0 m/s. The train is 48 meters long. How long will it take the conductor to reach the back of the train? 2.A ball is thrown on level ground at an angle of 25.0 degrees above the horizontal with an initial velocity of 18.0m/s. What is the range of the throw?
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.
