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.
![**Exercise 5.47**
A small model car with mass \( m \) travels at constant speed on the inside of a track that is a vertical circle with radius \( r = 15.0 \, \text{m} \) (Figure 1). The normal force exerted by the track on the car when it is at the bottom of the track (point A) is equal to \( 2.50mg \).
**Figure 1 Explanation:**
The diagram shows a circle representing the vertical circular track. The radius \( r \) is indicated by a line extending from the center of the circle to a point on the circumference. At the bottom of the circle, there is an arrow representing the direction of the normal force.
