Exploring motion Graphing

__________ Tells us the rate at which an object moves. ___________ Tells us the rate speed or direction changes. ___________ Is a change in position measured by distance and time. ___________ Tells the speed and direction of a moving object. A. Motion B. Speed C. Velocity D. Acceleration

When we graph speed Time is always plotted on the X-Axis. ​ Distance is always plotted on the Y-Axis

What kind of graph will a non-moving object make? Prediction Label your graph Make a prediction by drawing a line. Distance in meters Time in seconds

What kind of graph will a non-moving object look like? Actual Label your graph Volunteer come to the front and stand still for 5 seconds. Graph the distance traveled each second, then connect the dots. Distance in meters Time in seconds

Objects At Rest

The non-moving object (person): How far did the object (person) move? Zero meters ___________ is increasing to the right, but the person’s ___________ did not change. time distance moving The object is not _______________. stopped The object is _____________ or at rest.

What kind of graph will an object moving at a constant speed look like? Moving Object Prediction Label your graph Make a prediction by drawing a line. Distance in meters Time in seconds

What kind of graph will an object moving at a constant speed look like? Actual Moving Object Label your graph Volunteer come to the front walk across the room at a steady pace Graph the distance traveled each second, then connect the dots. Distance in meters Time in seconds

The moving object (person): How far did the object (person) travel over a period of time? five meters? Time is increasing to the ___________. right _______________ is increasing constantly with time.. Distance The object moves at _____________ speed. constant

What kind of graph will an object moving at a quick constant speed make? Prediction Quick Moving Object Label your graph Make a prediction by drawing a line. Distance in meters Time in seconds

What kind of graph will an object moving at a quick constant speed make? Actual Quick Moving Object Label your graph Volunteer come to the front and demonstrate sprint across room Graph the distance traveled, then connect the dots. Distance in meters Time in seconds

The object (person) moving at a quick constant speed: How far did the object (person) move? 14 meters? Time is ___________ to the right. increasing Distance is ___________ constantly with time. increasing steeper A ________ line means more distance was covered in a given time. The object moves at _______________________ speed. Constant quick

Let’s Review Which graph shows an object travelling at a faster speed? How do you know? This graph shows a faster moving object. We know that because this is the steeper line.

What will a graph of an object that gets faster over time look like? Speeding Up Object Prediction Label your graph Make a prediction by drawing a line. Distance in meters Time in seconds

What will a graph of an object that gets faster over time look like? Actual Speeding Up Object Volunteer start slow, then speed up across the room Label your graph

The object speeding up over time: How far did the object (person) move? 7 meters? Time is increasing to the right. Why is the line on the graph curved instead of straight? It is not a _____________ or steady increase. Because I am not going at a constant rate of speed constant This shows an increase in speed because the line is getting more _________. steep accelerating. The object is _______________________
