.A truck starts from rest at t = 0 and reaches a final speed v at time t. Which of the following statements is/are true if the acceleration of the of the truck is constant (and nonzero) during this time? The car travels a distance vt. The average speed of the car is v/2. The magnitude of the acceleration of the car is v/t. The velocity of the car remains constant.
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.
