Introduction
Calculating distance on a velocity-time graph is a fundamental skill in physics and engineering. This calculation allows you to determine how far an object has traveled over time when you know its initial velocity, time of travel, and acceleration. In this article, we will explore the concept of calculating distance on a velocity-time graph, provide the formula for this calculation, and offer an online calculator for practical use.
Formula
To calculate distance on a velocity-time graph, you can use the following formula:
Distance (d) = Initial Velocity (v₀) × Time (t) + 0.5 × Acceleration (a) × Time² (t²)
Where:
- Distance (d) is measured in meters (m).
- Initial Velocity (v₀) is the object’s starting velocity in meters per second (m/s).
- Time (t) is the duration of motion in seconds (s).
- Acceleration (a) is the rate of change of velocity in meters per second squared (m/s²).
How to Use
- Enter the initial velocity in meters per second (m/s).
- Input the time in seconds (s).
- Specify the acceleration in meters per second squared (m/s²).
- Click the “Calculate” button to determine the distance.
Example
Suppose you have an object with an initial velocity of 10 m/s, a time duration of 5 seconds, and an acceleration of 2 m/s². To calculate the distance on a velocity-time graph:
- Enter the initial velocity: 10 m/s.
- Enter the time: 5 seconds.
- Enter the acceleration: 2 m/s².
- Click “Calculate.”
The calculator will display a distance of 75 meters.
