Theme of the lesson

Moment of inertia of a perfectly rigid body

Lesson objectives

Use the Steiner theorem to calculate the moment of inertia of material bodies

Using the solution of a problem in angular variables, determine the linear displacement, speed, and acceleration of a rotating particle or a point on a rotating body

Success criteria

Express the rotational kinetic energy as a function of the angular velocity and the moment of inertia, and relate it to the total kinetic energy

Use the Steiner theorem to calculate the moment of inertia of material bodies

Compare analogies between physical quantities characterizing the translational and rotational motion.

To calculate the moment of inertia of a thin hoop, straight cylinder, disk, ball and a rectilinear rod relative to the axis passing through the centre of mass?

Language objectives

Subject-specific vocabulary & terminology:

Impulse of force, the rate of change of momentum, angular momentum, the law of conservation of angular momentum, rotational kinetic energy

Rotational kinetic energy is the energy of a body related to its rotation.

Basic dynamic characteristics of the rotational motion are moment of inertia and angular momentum L

Middle(5 minutes)

(10 minutes)

Teacher shows examples of calculating moment of inertia for different solid objects (solid sphere, cylinder, thin rod)

Group work - Zhigso

Students divided into groups where they are given conceptual questions, they discuss and answer to this questions, after that one of the students mixed and discuss answer of the first group with another group members if there is some differences in answers

Example of problem solving

Teacher shows and explains example of problem solving by PPT

Problem solving

Students given problems in the worksheet, one student works in the desk while others solve problems in their notebooks and check their solution from the desk, teacher can assist students that have difficulties in solving problem
