### Energy*

Energy is the ability to do work. Advanced civilizations use it and manage it wisely.

### Rotation*

Rotation, with the axis inside the object as it moves, has many equations that are analogous to linear motion.

### Gravity & Orbit*

Newton first explained it, but Gravity is rocket science. The force we feel on earth is actually one of the four fundamental forces in physics, and it works between any two masses at any distance. This week, we'll see how the people at NASA use Newton's equations.

### SHM & Waves*

A pendulum has a lot in common with waves. We'll learn some core ideas here that we'll use later when we study sound and light. We'll return to these ideas often, right up to the end of the year, when we study quantum mechanics and modern physics.

### Motion (linear)*

Analyze motion in one dimension. We'll start simple, but this is a foundation for much of the rest of the course, so learn it well.

### 2D Motion*

Motion in two dimensions relies on a little trigonometry. If trig functions are new to you, you'll have a few more things to memorize. Again, we'll use this on and off for the rest of the course, so learn it well.

### Forces*

The science of physics changed forever when Newton published his three laws in 1687.  It's still the core of physics today.

### Momentum*

Whenever things collide, it's useful to do momentum analysis.
