Learn the basics of motion, including how to determine if an object is in motion, measuring distance, calculating speed, and graphing motion. Explore the concepts of speed, velocity, reference points, and slope.

How do you know if you are moving? • Motion is relative. • Motion is defined as an object that is changing it's distance from another object.
What is a reference point? A place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point.
Measuring Distance SI unit for measurement: Distance = Meters Time = Seconds Speed = Meters/Second
Based on the video: Distance was 100m, Time: Started sliding at 8s, landed at 14seconds 14 - 8 = 6 seconds What is his speed?
Using the Formula Speed = Distance / time Speed = 100m / 6 s =
Answer 16.6 Label your answer!
A harder question still Calculate the Distance the boy travels if his speed is 2 meters per second and in 3 seconds.
How to Label Meters / Seconds = m/s Also known as Meters per second
A harder question still Calculate the Distance the boy travels if his speed is 2 meters per second and in 3 seconds. Formula is Speed times Time
Answer 2 meters/second times 3 seconds 2 x 3 = 6 What to label it?
6 METERS Calculate the Distance the boy travels if his speed is 2 meters per second and in 3 seconds.
Graphing motion You can show the motion of an object on a line graph in which you plot distance versus time. Y axis = distance (position) X axis = time At any point in time you can note the distance and time an object has traveled. SLOPE = steepness of line How fast one variable changes in realtionship to another.
Slope = rise / run Same as distance / time Different slopes show changes in speed. Slope
