Students will determine mathematical relationships among position, velocity, acceleration, & time and apply graphical and mathematical relationships to solve problems related to constant acceleration.

Warm-up Draw a motion diagram for each section of the graph...

EXPLORATION

Motion diagram...positive and negative acceleration...

EXPLANATION

Vocabulary terms to know...

none

algebraically re-arrange the definition of average acceleration in terms of final velocity.

Teach students how its done, do a couple example problems.

show how we get constant acceleration from the Position-time graph...free fall data

What do we mean by constant acceleration, give examples to support your answer.

3.3 - Free Fall

Objectives:

Students will...

define acceleration due to gravity

solve problems involving freefall

n order to explain the concept of acceleration due to gravity

Vocabulary terms to know...

free fall

acceleration due to gravity

WARM-UP

KWL - acceleration due to gravity.

ENGAGEMENT

Drop a piece of paper (uncrumbled)

Drop a crumble piece of paper

Drop a book

....which falls faster? Why? Does weight have anything to do with the rate at which objects fall.

EXPLORATION

Classwork

- Flash Cards for ALL EQUATION & VOCABULARY TERMS.

- Write a one page Summary of the Concept of Free Fall

...in your summary include the following...

* Galileo Galilei's experiment, his objective for the experiment and his conclusion.

* Explain what it means by acceleration due to gravity, give an example

* When do you treat acceleration due to gravity as positive or negative

* Explain what happen to the velocity and acceleration of an object as it is thrown upward, reaches the top of its flight and falls back to the person's hand.
