Thursday, February 13, 2020 Day 1 Science Starters Sheet 1. Please have these Items on your desk. Buggy Lab Agenda 2- Science Start: 1. What 2 things have you learned from the Buggy Lab? 2. What specific things make an airplane an actual airplane?
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 The longer the arrow, the greater the velocity. SLOW FASTER Left = negative direction 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 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. The car is moving at constant velocity! Each successive arrow is SMALLER, indicating the velocity is decreasing over time. changing. A dot indicates time is passing, but no arrow means no velocity. The arrows are all the same size, this indicates that the velocity is NOT
