A racing car starts from rest at t= 0 and reaches a final speed v at time t. If the acceleration of the car is constant during this time, which of the following statements is true? O a. The velocity of the car remains constant. O b. The car travels a distance = VX t. Oc None of statements (a) through (d) is true. Od. The magnitude of the acceleration of the car is dv/dt. O e. The average speed of the car is 2v.
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.
