Understanding Distance-Time Graphs
What is a Distance-Time Graph?
A distance-time graph is a visual representation of an object's motion, illustrating how the distance traveled changes over a period of time. The graph's axes typically include:
- Horizontal axis (x-axis): Represents time (usually in seconds, minutes, or hours).
- Vertical axis (y-axis): Represents distance from a starting point (usually in meters, kilometers, miles, etc.).
This type of graph is fundamental in physics as it helps analyze the motion of objects, determine speed, and understand different types of motion.
Key Features of a Distance-Time Graph
To interpret and answer questions effectively, one must understand the key features of these graphs:
- Slope: Represents the speed or velocity of the object.
- Straight line: Indicates constant speed.
- Curved line: Signifies acceleration or deceleration.
- Horizontal line: Implies the object is stationary.
- Steeper slope: Indicates higher speed.
- Shallow slope: Indicates lower speed.

Common Questions Addressed by the Gizmo Answer Key
1. How to Read a Distance-Time Graph
The answer key provides step-by-step guidance on reading graphs:
- Identify the time interval.
- Determine the distance covered within that interval.
- Calculate the speed by finding the slope of the line.
2. How to Calculate Speed from the Graph
Speed (or velocity) is calculated as:
\[ \text{Speed} = \frac{\text{Change in Distance}}{\text{Change in Time}} \]
The answer key offers detailed solutions for calculating slopes of different segments, including:
- Using two points on the line.
- Deriving average speed over a time interval.
- Interpreting varying slopes for acceleration.
3. Interpreting Different Types of Motion
The answer key explains how to identify:
- Constant speed: When the graph is a straight, diagonal line.
- Acceleration: When the slope increases over time (curved upward).
- Deceleration: When the slope decreases (curved downward).
- Stationary objects: Horizontal lines.
4. Answering Specific Gizmo Questions
The answer key covers typical questions such as:
- "What is the speed of the object during a specific interval?"
- "Does the object stop or change speed?"
- "Estimate the total distance traveled."
