Concept explainers

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.

# Understanding Motion Through Graphs: An Educational Overview

## Introduction
A red car and a green car move towards each other. Below, we examine a graph illustrating their motion. At \( t = 0 \) seconds, their initial positions are:
- Red car: \( x_{\text{red}} \) at \( t = 0 \): \( -30 \) m (blue line on the graph)
- Green car: \( x_{\text{green}} \) at \( t = 0 \): \( 490 \) m (red line on the graph)

The green car has a constant speed of 35 m/s, and the red car starts from rest. The problem posed is: What is the acceleration of the red car?

## Graph Explanation
### Visual Representation
- **Diagram:** Depicts the initial positions of the red car at \( x_{\text{0,red}} \) and the green car at \( x_{\text{0,green}} \).
- **Position vs. Time Graph:**
- The blue line represents the position of the red car over time.
- The red line represents the position of the green car over time.
- Both lines intersect at \( t = 12 \) seconds.
- The x-axis represents time \( t \) in seconds (s), ranging from 0 to 12 seconds.
- The y-axis represents position \( x \) in meters (m).

## Theoretical Application
### True/False Questions
1. **True or False:** The instantaneous value of a velocity vs. time graph is the slope of the corresponding position vs. time graph.
- **True**

2. **True or False:** If you calculate the area under the line of a velocity vs. time graph, it equals the distance the object moved.
- **True**

3. **True or False:** The instantaneous slope of a velocity vs. time graph is the acceleration at that moment.
- **True**

4. **True or False:** If you calculate the area under the line of an acceleration vs. time graph, it equals the velocity of the object.
- **True**

### Projectile Motion Question
5. **Problem Context:** A quarterback throws the ball towards his receiver.
- **a.** At the very top of the ball’s arc, what is the velocity of the vertical component of the ball?
- **Answer:** 0 m
