Motion Maps

Motion Map Parts The dot: Indicates the position of the object The arrow: indicates the direction and speed of the object. (sometimes called a vector)

Dots and Arrows Together Dot alone = not moving. Dot and arrow together: Position, direction and speed.

Direction and Size Right = positive direction Left = negative direction The longer the arrow, the greater the velocity. SLOW FASTER FASTEST

The grid…. Motion Maps are drawn along a grid to show the position of the object. Draw a minimum of 3 arrows to show a pattern. Forward, Constant Velocity, Slow Forward, Constant Velocity, Faster

More Complicated Motion… The object moves forward at constant velocity, then stops and remains in place for two seconds, then moves backward at a slower constant velocity.

Example 1 Draw a motion map. The car is accelerating! Each successive arrow is longer, indicating the velocity is increasing. Draw a motion map.

Example 2 The car is accelerating! The car is NOT moving. Each successive arrow is SMALLER, indicating the velocity is decreasing over time. The car is NOT moving. A dot indicates time is passing, but no arrow means no velocity. The car is moving at constant velocity! The arrows are all the same size, this indicates that the velocity is NOT changing.
