To begin, consider a car moving with a constant, rightward (+) velocity- say of +10 m/s. If the position-time data for such a car were graphed, then the resulting graph would look like the graph at the right. Note that a motion described as a constant, positive velocity results in a line of constant and positive slope when plotted as a position-tim...
The shapes of the position versus time graphs for these two basic types of motion - constant velocity motion and accelerated motion (i.e., changing velocity) - reveal an important principle. The principle is that the slope of the line on a position-time graph reveals useful information about the velocity of the object. It is often said, "As the slo...
Consider the graphs below as example applications of this principle concerning the slope of the line on a position versus time graph. The graph on the left is representative of an object that is moving with a positive velocity (as denoted by the positive slope), a constant velocity (as denoted by the constant slope) and a small velocity (as denoted...
As a final application of this principle of slope, consider the two graphs below. Both graphs show plotted points forming a curved line. Curved lines have changing slope; they may start with a very small slope and begin curving sharply (either upwards or downwards) towards a large slope. In either case, the curved line of changing slope is a sign o...
Use the principle of slope to describe the motion of the objects depicted by the two plots below. In your description, be sure to include such information as the direction of the velocity vector (i.e., positive or negative), whether there is a constant velocity or an acceleration, and whether the object is moving slow, fast, from slow to fast or fr...
Mar 31, 2022 · This article will cover the basics for interpreting motion graphs including different types of graphs, how to read them, and how they relate to each other. Interpreting motion graphs, such as position vs time graphs and velocity vs time graphs, requires knowledge of how to find slope.

Aug 17, 2022 · The effects of forces. Friction. Changing shapes. Temporary changes of shape. Springs and wires. In this section, we will learn how different objects and their size affect the impact of the forces applied to them. Forces are pushes/pulls of one thing onto another. An example of a force is gravity.

INTRODUCTION. Physics is the study of objects (entities); specifically, objects that exist. In Physics, we must have an object for else there would be nothing to study, nothing to perform activities or motion. Only an object can serve as a valid noun in a sentence of Physics with the capability to perform actions.
