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.

![### Average Velocity Calculation for a Moving Car
The data in the following table describe the initial and final positions of a moving car. The elapsed time for each of the three pairs of positions listed in the table is 0.50 seconds. Review the concept of average velocity and then determine the average velocity (magnitude and direction) for each of the three pairs. Note that the algebraic sign of your answers will convey the direction.
#### Table of Positions
| | Initial position \( x_0 \) | Final position \( x \) |
|---|---------------------------|-----------------------|
| (a) | +2.0 m | +6.0 m |
| (b) | +6.0 m | +2.0 m |
| (c) | -3.0 m | +7.0 m |
**Concept Breakdown:**
- **Initial and Final Positions:** The positions are given in meters (m).
- **Elapsed Time:** 0.50 seconds for each pair.
**Steps to Calculate Average Velocity:**
1. **Determine Displacement:** For each pair, subtract the initial position \( x_0 \) from the final position \( x \).
2. **Calculate Average Velocity:** Divide the displacement by the elapsed time (0.50 s).
\[ \text{Average Velocity} = \frac{x - x_0}{\text{Elapsed Time}} = \frac{x - x_0}{0.50 \text{ s}} \]
**Note:** The resulting average velocity will indicate direction based on the algebraic sign; a positive sign indicates movement in the positive direction, and a negative sign indicates movement in the negative direction.
### Calculations
1. **Pair (a):**
- _Initial Position \( x_0 \)_: +2.0 m
- _Final Position \( x \)_: +6.0 m
- _Displacement_: \( 6.0 \text{ m} - 2.0 \text{ m} = 4.0 \text{ m} \)
- _Average Velocity_: \(\frac{4.0 \text{ m}}{0.50 \text{ s}} = 8.0 \text{ m/s} \) (positive direction)
2. **Pair (b):**
- _Initial Position \( x_0 \)_: +6.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb2c8c9d8-cb7d-4bb3-b241-ba372e4ba26e%2F8681bbdd-b5dd-461a-96d4-a60d7465b9d3%2Farwntof_processed.jpeg&w=3840&q=75)
