We started the day going over any momentum questions you have difficulty with.

Then we went through the Static Equilibrium questions from old government exams.

Today we started the study of **Circular motion.**

I used PowerPoints to teach the concepts. Here are the videos of these lessons:

Introduction to Centripetal Force

Centripetal Force Part Two

Centripetal Force Part Three

Try the SNAP book questions on pages 220 – 222. Here are the solutions:

Page 220 Page 220 – 222 Page 222

Then we looked at **Vertical Circular Motion**. Here are the videos of the lessons:

Vertical Circular Motion Part One

Vertical Circular Motion Part Two

Try the SNAP book questions on pages 227 – 230. Here are the solutions:

Page 227 Page 228-230 Page 230

We then started Newton’s Law of Universal Gravitation. Try the questions on pages 235 – 237 in the SNAP book. Here are the answers:

Page 235-236 Page 236-237

Next we looked at Gravitational Field Strength. Try the questions on pages 241 – 242 in the SNAP book. Here are the answers:

Page 241-242

Next we looked at Satellites. Here are the videos that we watched in class:

The Satellite Formula

Using the Satellite Formula

I handed out two worksheets on Gravitation and Satellites.
