FOR PARENTS & TUTORS: This is a longer chapter. This chapter is often problematic for many Physics 12 students as we are diving into circular motion, which can be a conceptual leap for some students. The concept of a "Gravitational Well" is also a foreign and challenging concepts to embrace. Furthermore, the algebra and calculations required in this chapter can be very long and tedious, students are expected to be at a more mature level in their Mathematics skills by this point in the course.

In this chapter, my Physics 12 class will be focusing on learning/reviewing the following main skills:
In this chapter, my Physics 12 class will be focusing on learning/reviewing the following main skills:
Calculating Centripetal Acceleration & Centripetal Force.
Uniform and non-uniform circular motion in the horizontal and vertical direction. (Constant Tangential Velocity, Minimum Velocity, Normal force, Tension Force, Friction Force, Coefficient of Friction, Orbital Velocity, Orbital Period, Orbital Radius).
Circular Motion at an angle (The Conical Pendulum & Banked Curves)
Conservation of Energy and Circular Motion.
The Gravitational Constant.
Calculating the gravitational force of attraction between any two masses in space using Newton's formula for universal gravitational force.
Calculating Gravitational Field Strength
Calculating Orbital Velocity, Escape Velocity, Orbital Period, Orbital energy (E, Ep & Ek) as well as the physics of changing orbits.
The Area under a Fg - Distance graph represents Work.
The shape and behavior of Fg - R graph, g - R graph, and an Ep - R graph.
The Basics of Kepler's Laws
Newton's 2nd law can be extended to circular motion and that a "center seeking" force (Centripetal Force - A Push or a Pull) will accelerate a mass towards the center of a "turn".
Circular Motion is only considered as USM if the tangential velocity of the mass is constant.
Friction Force helps keep a mass turning on the road.
Mass in the absence of continuous Centripetal Force will move tangential to the orbit.
Understanding that Centrifugal Force is a fictious force.
Linear Velocities at different locations from the center of a rotating platform are not the equal, but their orbital period is.
Centripetal Force plays a role in helping us stay anchored to the ground.
This is the chapter where students learn to "equate" different physical quantities and their equation to each other based on the context of the problem. Formulas and equations in this chapter can tend to grow larger and more algebraic manipulations are used to help simplify expressions as well as calculations.
Gravity is an attractive force only and that Gravitational Force obeys the Inverse Square Law
The concept of a 'Force Field" is introduced and how it too obeys the Inverse Square Law.
The concept of a Gravitational Well and that Gravitational Force, Force Field Strength, and Gravitational Potential Energy is set to ZERO at a distance "far enough" at infinity.

My practice tests have always been, are, and will always be intended as a general guide to help students prepare for unit tests. You must review my notes and work through the questions in the review package in addition to the practice test. As I’ve emphasized in class, don’t just learn how to solve a specific problem or set of problems—focus on understanding the underlying Physics and Math concepts. Do not expect to see identical questions with different values on your test. If you do, you’ll be disappointed.
If there are any typos, wrong calculations, or wrong answers please tell me politely. Thank you
