<em>The y-intercept of a position-time graph of an object gives the average velocity of the object is False.</em>
<u>Answer:</u> <em>False. </em>
<u>Explanation:</u>
The initial position of the object can be obtained by calculating the Y intercept of a position-time graph. In a position-time graph, the independent variable is time and dependent variable is position. Y axis is the position axis and x axis is the time axis.
The equation of the graph is given by . m is the slope of the graph and c is the y intercept. When a particle starts from the origin its y intercept is zero.
The nature of the graph gives us an idea about velocity. When the velocity is positive, the position- time graph has positive slope and when the velocity is positive the graph has negative slope.
