A river flows due south with a speed of 1.5 m/s. You steer a motorboat across the river; your velocity relative to the water is 3.7 m/s due east. The river is 800 m wide. a. What is the magnitude of your velocity relative to the earth? b. What is the direction of your velocity relative to the earth? c. How much time is required to cross the river? d.
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.
