Motion Graphs (2 of 8) Position vs. Time Graph Part 2, Acceleration | Summary and Q&A

TL;DR
Analyzing graphs to determine motion direction and speed changes.
Key Insights
- 🫥 Straight lines on a position vs. time graph represent constant velocity.
- ❎ Positive slope indicates motion in the positive direction, while negative slope indicates motion in the negative direction.
- 💱 Changes in slope signify changes in velocity, indicating acceleration or deceleration.
- 🐎 Curves on the graph show motion with varying speed, such as speeding up or slowing down.

Questions & Answers
Q: How does the slope of a position vs. time graph relate to velocity?
The slope of the graph represents the velocity of an object, with positive slopes reflecting positive velocities and negative slopes indicating negative velocities.
Q: What does a straight line on a position vs. time graph signify?
A straight line on the graph indicates constant velocity, where the object is moving at a consistent speed in one direction.
Q: How can changes in slope on a position vs. time graph indicate acceleration or deceleration?
Changes in the slope of the graph, either increasing or decreasing, signify changes in velocity, reflecting acceleration (speeding up) or deceleration (slowing down).
Q: What type of motion can be represented by a curve on a position vs. time graph?
A curve on the graph can represent motion with varying velocity, such as an object accelerating or decelerating over time.
Summary & Key Takeaways
-
Position vs. time graphs show motion in one dimension with straight lines indicating constant velocity.
-
Slope of the line equals velocity, with positive slope indicating positive velocity and negative slope indicating negative velocity.
-
Changes in slope on the graph indicate changes in speed (acceleration) or direction of motion.
