You get to 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 at a constant speed on a linear road.
What does the slope of a position-time graph represent?
~ The slope of a position-time graph represents the displacement in unit time, or the velocity of the object.
How do you find the slope of the position-time graph?
~ To find the slope of the position-time graph, you must draw a triangle whose hypotenuse is the graph line and whose perpendicular sides are parallel to the axes. The slope can be calculated by dividing the vertical side by the horizontal side of the triangle, or by taking the tangent of the angle that the graph line makes with the horizontal side.
What can you conclude if the angle between the graph line and the horizontal line increases?
~ The velocity of the object has increased.
