A hypothetical spaceship takes a straight-line path from the Earth to the moon, a distance of about 400,000 km. Suppose it accelerates at 10.0 m/s2 for the first 20 minutes of the trip, then travels at constant speed until the last 20 minutes, when it accelerates at -10.0 m/s2, just coming to rest as it reaches the moon. What total time in minutes is required for the trip?
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.
