graphs
graphes mpl

charts . Ways to show data pictorially, where we can see the patterns in the graph more clearly than we see them in the table.

Graphs show how two (or sometimes more) variable quantities are related to each other. Graph A below shows that X is proportional to X. In (b) we find that y is inversely proportional to X. We try in physics
Obtaining graphs such as (a) and (c) - straight lines slanting up or down, and perhaps passing through the origin 0 (the point with coordinates (0=X))(y=0). These graphs show how x and y each other very clearly.

It is often useful to find the slope and intercept of the graph. The slope, or “gradient” (m), is the ratio x/y (see diagrams above). The “intercept” is the value of y at which the axis of the graph crosses, and it is the value of y when it is zero. The values ​​of m and c in the case of a straight graph give the following line equation: y=mx+c.

When the acceleration a of a body is constant, the graph of speed versus time is a straight line, and it may be as follows:

This drawing has the equation v=mtc. Here m is the ratio (t2 - t1) / (V2 - V1) which equals a, while C equals V0. It is usual to write this equation as follows: V2 = V1 + at.

gravity

Sinker. gravity. One of the basic types of force.
Gravity is the attraction between masses. The actual cause of gravity is not known. Some theories say that it is related to gravitational waves, and others say that there are particles called gravitons.
