3 Calculating displacement using area of a triangle

 

 
Topic

Number One

 

Activity One:

What is Inertia? Demo with “Pat”

 

Activity Two

Besides uniform motion, what are three things that remain constant.

Paradox: Define? Example?

Change: examples of change?

Humor: Is it unique to humans?

Topic

Number Two

Go through review questions.

Questions to focus on:

a)   What “story” is a graph telling? (matching a graph with a vocab term)

b)   How do we use speed and time to calculater more than acceleration? ( How can we have positive velocity but negative acceleration?)

 

 
Topic

Number Three

 

Using the area of a triangle ( 1/2bxh) to calculate displacement.

 

Area of a triangle is ½ base time height

 

Substitute values of base as time and height as velocity.

 

Displacement = ½ times sec/1 times meters/sec

 

Units that cancel out are time!

 

So final unit is distance or distance from original point.

 

 

Example

 

Total time = 5 seconds

Final Speed = 20 meters / second

 

D= ½ x 5 sec x 20 m/s

 

= ½ x 100 m

 

= 50 meters!
