Present you Findings

Question

Make a graph of the data. You may use a graphing program. Think about what data should be on the y-axis and the x-axis. Be sure to label each axis and note the units used in the measurements. Be sure to draw a smooth curve through the points. Do not just connect the dots. Upload your data and graph in the essay box below and answer the following questions.

1. Did the car travel at a constant speed?
2. What was the average speed of the car?
3. What are some practical applications for determining the motion of an object?

Answer 1

You haven't sent your data, but I assume it is distance / time.

Then you should plot time on the x axis (independent variable) and distance on the y (dependent).

Then draw a smooth curve as close to the points as you can.

(1) . If you can draw a single straight line through all the points, then the car is travelling at a constant speed

(2) If your first point is (x1,y1) and last point (x2,y2) this will be (y2-y1) / (x2-x1) [ total distance / total time ]

(3) This question isn't very clear. Odometer on a car ?
