Lesson 2.1

Motion
Reference Points
Directions and signs

Change in position over time
If position does not change, object is not moving

mOTION

Helps identify if an object is moving
Point of comparison
Tells you the position, location, and distance of the object

Reference Points

Left is negative and right is positive

North and East are positive

South and West are negative

Signs and Directions

Multiple Choice

I'm going to the left. What sign will this be?

Positive

Negative

Multiple Choice

An object does not change its position. Is the object moving?

YES

Lesson 2.2

Analyzing a distance VS time graph

Multiple Choice

Which line is the fastest?

Multiple Choice

Which line is slowest?

Multiple Choice

Which line indicates that the object is not moving?

Multiple Choice

How many meters did the object move from 12:30-14:00?

Lesson 2.3

total distance
Displacement

SUM of all distance an object travels
direction not involved

Total distance

distance between start point and end point
direction is involved

displacement
