Straight Line on Distance vs Time^2 Graphs

In summary, the question is asking for an explanation of why the graphs should be a straight line for a Distance vs Time^2 graph. The professor clarified that on a position vs. time graph, a constant velocity results in a straight line, but for this problem, the graph is plotting distance vs. t^2.

Homework Statement



The question asks me to explain why the graphs should be a straight line?
We had to make a Distance vs Time^2 graphs.

The Attempt at a Solution



On a position x time graph If the ball is falling only way it can be a straight line if the velocity is constant , right?

I don't have an electronic copy of the graphs on me but here is how the professor answered it.

That is correct, you get a curve (what shape?) when plotting position vs. time for an object accelerating with constant acceleration. But this problem asks you to plot distance on the y-axis vs. t^2 on the x axis.

Thanks a lot.
 

1. What is a straight line on a distance vs time^2 graph?

A straight line on a distance vs time^2 graph represents a constant acceleration. It indicates that the object is moving with the same acceleration throughout its motion.

2. How do you interpret the slope of a straight line on a distance vs time^2 graph?

The slope of a straight line on a distance vs time^2 graph represents the acceleration of the object. The steeper the slope, the greater the acceleration.

3. What does the y-intercept of a straight line on a distance vs time^2 graph represent?

The y-intercept of a straight line on a distance vs time^2 graph represents the initial velocity of the object. It indicates the velocity at the beginning of the motion.

4. Can the slope of a straight line on a distance vs time^2 graph be negative?

Yes, the slope of a straight line on a distance vs time^2 graph can be negative. This would indicate that the object is decelerating, or slowing down, during its motion.

5. How can you use a distance vs time^2 graph to calculate the acceleration of an object?

To calculate the acceleration of an object from a distance vs time^2 graph, you can use the formula a = 2d/t^2, where a is the acceleration, d is the distance, and t is the time. Simply plug in the values from the graph and solve for acceleration.
