Motion can be plotted on a graph by labeling the X- axis with TIME and the Y-axis DISTANCE.

Warm Up A particle moves vertically(in inches)along the x-axis according to the position equation x(t) = t4 – 18t2 + 7t – 4, where t represents seconds.

Graphing Activity Describing the motion of an object is occasionally hard to do with words. Sometimes graphs help make motion easier to picture, and therefore.

Graphing Motion, Speed and Velocity. Graphs of Motion A Distance vs. time graph that is a straight line always means the object moves the same.

Principles of Physics

 motion along a straight line path, motion in one dimension  Which way are you headed?  How far did you go?  How fast are you going?  Is your speed changing? How can we represent the motion of an object visually?

y axis: displacement x axis: time m = slope x = horizontal variable y = vertical variable Direct relationship Indirect relationship Constant relationship

Always include: 1. Axis labels with units 2. Appropriate scales (each box can be 1, 2, 4, or 5 only) 3. A detailed title describing the information in the graph

1. On the grid provided plot the data given in the Table. 2. Draw a best fit line Displacement (m)Time (s) Time (s) Displacement (m) Displacement Versus Time for an Unknown Object

3. Calculate the slope of the graph. (Always use points that are on the best fit line!!!) 4. What does the slope of the graph represent? velocity

t d No, velocity is constant. The line is straight, so the slope is not changing 1. Is the object moving forward or backward? 2. Is the object’s velocity changing? Forward

No, velocity is constant. The line is straight, so the slope is not changing 1. Is the object moving forward or backward? 2. Is the object’s velocity changing? Backward t d

No, velocity is 0 1. Is the object moving forward or backward? 2. Is the object’s velocity changing? Neither, displacement is not changing, so the object is not moving t d

Yes, the object is accelerating. Its speed is increasing (slope gets steeper) 1. Is the object moving forward or backward? 2. Is the object’s velocity changing? Forward d t

Yes, the object is accelerating. Its speed is decreasing (slope levels out) 1. Is the object moving forward or backward? 2. Is the object’s velocity changing? Forward t d
