Question

The y-intercept of a position-time graph of an object gives the average velocity of the object.

Answer 1

The y-intercept of a position-time graph of an object gives the average velocity of the object is False.

Answer: False.

Explanation:

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 $y =mx + c$. 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.
