The distance between each mark on the scale is 14 meters and the time that passes between two consecutive pictures is 7 seconds. 1a. Which is the best description of boat's motion? -The boat is moving forward. -As time goes on, the position of the boat is increasing. -The boat is moving in a positive direction at a constant speed. -The boat is moving at a constant speed. -This boat travels for the total time of 7 seconds and in that time it covers 14 meters. -The boat travels 14 meters every 7 seconds. -This is a red boat that moves to the right under the influence of air. -The position of the boat changes. 1b. What is the speed of this boat? (m/s) 1c. Where is this boat at t=4 sec? (m) 1d. Assuming the motion of this sailboat stays the same, where will it be at t=12 sec? (m)
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.
