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.
![### Position vs. Time and Velocity vs. Time Graphs
#### Introduction
Understanding the relationship between position, time, and velocity is crucial in physics, especially in kinematics, which deals with the motion of objects. Below, is a graph representing the position versus time (distance-time) for an object and a corresponding graph that you'll create to represent the velocity versus time for the same object.
#### Position vs. Time Graph Explanation
The **left graph** is a **Position vs. Time graph**:
- The y-axis represents **Position (m)** measured in meters.
- The x-axis represents **Time (s)** measured in seconds.
The graph has the following key points:
- From 0 seconds to 5 seconds, the position increases from 0 meters to 20 meters, indicating the object is moving away from the origin.
- From 5 seconds to 10 seconds, the position remains constant at 20 meters, indicating the object is stationary.
- From 10 seconds to 15 seconds, the position increases from 20 meters to 50 meters, indicating the object is moving away again.
- From 15 seconds to 20 seconds, the position decreases from 50 meters back to 0 meters, indicating the object is returning to the origin.
#### Velocity vs. Time Graph Explanation
Using the Position vs. Time graph, we can derive the **Velocity vs. Time graph** as follows:
The **right graph** is a **Velocity vs. Time graph**:
- The y-axis represents **Velocity (m/s)** measured in meters per second.
- The x-axis represents **Time (s)** measured in seconds.
For each segment in the Position vs. Time graph, the velocity can be calculated by the formula:
\[ \text{Velocity} = \frac{\Delta \text{Position}}{\Delta \text{Time}} \]
Based on this, we find:
- **From 0 to 5 seconds**:
- Position changes from 0 m to 20 m.
- Time interval is 5 seconds.
- Velocity: \( \frac{20 \text{ m} - 0 \text{ m}}{5 \text{ s} - 0 \text{ s}} = 4 \text{ m/s} \)
- The velocity is constant at 4 m/s.
- **From 5 to 10 seconds**:
- Position remains constant at 20 m.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff680fd89-90ed-42e9-8d06-46add0eeb22d%2F74810f82-c0fa-4572-9049-1680790d93cd%2F41ha7k_processed.png&w=3840&q=75)
