# Momentum

Momentum, impulse and the relationship to force. Conservation of momentum with collisions, elastic and inelastic.

# Energy

Work, kinetic energy, the work-energy theorem, gravitational potential energy, spring potential energy and conservation of energy.

# UCM, Gravity and SM

Phases of the Moon and tides.

Uniform Circular Motion, Newton’s Universal Law of Gravitation and the gravitational field and the Standard Model of Elementary Particle Physics.

# Two-Dimensional Kinematics

## Initially Horizontal Motion & Relative Motion

Includes examples of four different cases for initial horizontal motion. Relative motion is illustrated with four cases of a boat on a river.

## The Range Equaton

Derivation of the Range Equation and properties of projectile motion. Solving problems with numbers.

## Position, Velocity & Acceleration

Now with vectors and vector components!

## Vectors

Vectors, components, rectangular and polar notation, adding vectors.

# One-Dimensional Kinematics

## More Motion Graphs & Intersecting Trajectories

Horizontal-motion and free-fall problems are reconsidered with motion graphs. We also consider the intersections of trajectories and constructing acceleration, velocity and position graphs given any one of them.

## Working Problems

Horizontal motion and free-fall are considered.

## Many ways to solve a problem!

The same problem is solved …

• … using the area under the velocity curve.
• … using the slope of the velocity to find acceleration.
• … using two definitions of average velocity.

## Motion Graphs & Kinematic Equations

Reading motion graphs, going between position, velocity & acceleration, derivation of the full position equation using motion graphs and the derivation of the time-independent form.

## Position, Velocity & Acceleration

The basic definitions of the variables that describe motion, the difference between speed & velocity, displacement & distance, and the first few kinematics equations.

# Working with Data

Inverse and direct relationships, constants,proportions and squares. Working with linear functions and linearizing power functions to extract the equation. Download the notes:

# What is Physics?

The cool video Concept Trailers may be found here. The PhET Physics simulations may be found here. We also looked at Einstein’s Most Famous Equation. These notes are far from complete, but they might give you a taste of things to come. We will use some of these simulations later in the year.
