Graphing Motion Worksheet: Analyze displacement, velocity, and acceleration over time for different motion patterns.

Problem Overview:

The task involves completing a series of graphs for displacement-time (\(d-t\)), velocity-time (\(v-t\)), and acceleration-time (\(a-t\)) based on the given patterns. Each row represents a different motion scenario, and the goal is to match the correct \(v-t\) and \(a-t\) graphs with the provided \(d-t\) graph.

Key Concepts:

1. Displacement-Time (\(d-t\)) Graph:
- Slope = Velocity (\(v\)).
- A straight line indicates constant velocity.
- A curved line indicates changing velocity (acceleration).

2. Velocity-Time (\(v-t\)) Graph:
- Slope = Acceleration (\(a\)).
- A straight horizontal line indicates constant velocity (zero acceleration).
- A curved line indicates changing acceleration.

3. Acceleration-Time (\(a-t\)) Graph:
- A straight horizontal line indicates constant acceleration.
- A curved line indicates changing acceleration.

Solution Approach:

For each row, we will analyze the \(d-t\) graph and determine the corresponding \(v-t\) and \(a-t\) graphs based on the relationships between displacement, velocity, and acceleration.

- \(v-t\) Graph: Curve that rises and then falls.
- \(a-t\) Graph: Line that starts positive and becomes negative.

#### Row 7:

- \(a-t\) Graph: Line that starts negative and becomes positive.

#### Row 8:
- \(d-t\) Graph (Problem 36): S-shaped curve.
- Analysis: Velocity changes from increasing to decreasing (positive acceleration, then negative acceleration).
- \(v-t\) Graph: Curve that rises and then falls.
- \(a-t\) Graph: Line that starts positive and becomes negative.

#### Row 9:
- \(d-t\) Graph (Problem 37): Parabolic curve (concave down, then concave up).
- Analysis: Velocity decreases to zero, then increases (negative acceleration, then positive acceleration).
- \(v-t\) Graph: Curve that falls to zero and then rises.
- \(a-t\) Graph: Line that starts negative and becomes positive.

#### Row 10:
- \(d-t\) Graph (Problem 38): Horizontal line, then straight line with negative slope.

- Analysis: Zero velocity, then constant positive velocity.
- \(v-t\) Graph: Horizontal line at \(v = 0\), then horizontal line above the \(t\)-axis.
- \(a-t\) Graph: Horizontal line at \(a = 0\), then horizontal line at \(a = 0\).

#### Row 12:
- \(d-t\) Graph (Problem 40): Horizontal line, then parabolic curve (concave up).
- Analysis: Zero velocity, then velocity increases (positive acceleration).
- \(v-t\) Graph: Horizontal line at \(v = 0\), then straight line with positive slope.
- \(a-t\) Graph: Horizontal line at \(a = 0\), then horizontal line above the \(t\)-axis.
