You get to discover and learn what physicists mean when they talk about position, displacement, and velocity. Then observe these concepts in action with position-time and velocity-time graphs.
After completing this tutorial, you will be able to complete the following:
What is one-dimensional motion?
~ One-dimensional motion is the movement of an object traveling in a straight line at a constant speed.
Describe the appearance of a graph of velocity-time an object in one-dimensional motion.
~ On a graph, one-dimensional motion, or the movement of an object traveling in a straight line at a constant speed, appears as a horizontal line that is constant throughout the movement of the object.
On a velocity-time graph of one-dimensional motion, how can you determine the amount of displacement of an object within a specific amount of time?
~ To find the amount of displacement of the object within the specified time interval, you must multiply the velocity and the time. The product of the velocity and the elapsed time represents the area between the horizontal velocity-time graph line and the time axis, which is the amount of displacement of the object.
On a velocity-time graph, how can you tell if an object is moving in the positive direction or if it is moving in the negative direction?
~ On a velocity-time graph, the graph line for an object moving in the positive direction appears above the time axis, while the graph line for an object moving in the negative direction appears below the time axis. Similarly, if the area formed by the graph line and the time axis is above the time axis, it represents a positive displacement; if the area formed by the graph line and time axis is below the time axis, it represents a negative displacement.
