Wednesday, February 15, 2017 Day 1 1. Please have these Items on your desk. Science Starters Sheet Science Notebook Agenda Buggy Lab 2- Science Start: https://www.youtube.com/watch?v=9G1dhkRJ3ak Write four motion vocabulary words from the video. Physics goal sheet. Write your starting point on the Line A of the learning activity section. Rate what level you are currently at within the physics unit. Plot a point on the graph.

White board the buggy lab . . . . On the board you should have: 1. One line of best fit graph. 2. Explain your graph. What is it showing? 3. What is your evidence?

Table of contents update Page 29 2/15 Motion Notes

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. Positive Direction, Constant Velocity, Slow Positive Direction, Constant Velocity, Faster

More Complicated Motion… The object moves forward(positive) at constant velocity, then stops and remains in place for two seconds, then moves backward(negative) 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.
