Inertia Lesson Plan

7.7 Investigation: The Relationship Between Motion and Force.

1. Teaching Content: Inertia Phenomena

II. Teaching Objectives

1. Know what inertia is.

2. Understand the difference between inertia and force.

3. Understand that all objects have inertia under any circumstances, and inertia is an attribute of the object.

4. Understand the hazards of inertia and how to utilize it, and be able to explain everyday inertial phenomena.

III. Teaching Focus: The Concept of Inertia

Section Four: Understanding of Inertia Concepts and Explanation of Inertial Phenomena

Teaching Process:

1). Observe some inertia experiments to answer the experimental phenomena.

1. Press down hard on the egg to pop it out from the paperboard. The egg should not fly out with the paper, but instead fall into the cup.

2. When the following chess piece is knocked out, the piece above it does not fly out but instead falls onto the table.

3. The car stops due to obstruction, but the block does not stop; instead, it tips forward.

The teacher guides the students to analyze and conclude that a stationary object maintains its original stationary state; a moving object maintains its original motion state; and together with the students, they analyze and conclude the concept of inertia:

We call the property of an object to maintain its original motion state unchanged inertia.

(2) Please have students describe and discuss additional examples of inertial phenomena.
