I. II. III. IV. D The acceleration of the toy car is zero. The acceleration of the toy car is nonzero. The acceleration of the toy car is directed vertically upwards. The acceleration of the toy car is purely horizontal. B E
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.
A toy car is observed to traverse the vertical track ABCDE as shown, starting from point A. Assuming that there is negligible friction between the toy car and the track, which of the following statements is/are TRUE about the acceleration of the toy car when it is at point B? (At this point the car is rising upwards the circular loop.)
