## Football physics: The "impossible" free kick - Erez Garty

In 1997, Brazilian football player Roberto Carlos set up for a 35 meter free kick with no direct line to the goal. Carlos’s shot sent the ball flying wide of the players, but just before going out of bounds it hooked to the left and soared into the net. How did he do it? Erez Garty describes the physics behind one of the most magnificent goals in the history of football.

## Ideas to Review for AP 1 Test

Below are a series of simulated situations used to illustrate major ideas in physics. Next to each link I give you a few things to consider as you explore the environment that was recreated in the program.
Dolores Gende's insight:

Series of simulations that illustrate physics concepts.

John Myrick's curator insight,

Take a look at these questions, you will see something like this on tomorrows test. Good luck!

## How Building a Black Hole for Interstellar Led to an Amazing Scientific Discovery | WIRED

Kip Thorne looks into the black hole he helped create and thinks, “Why, of course. That's what it would do.”

This particular black hole is a simulation of unprecedented accuracy. It appears to spin at nearly the speed of light, dragging bits of the universe along with it. (That's gravity for you; relativity is superweird.) In theory it was once a star, but instead of fading or exploding, it collapsed like a failed soufflé into a tiny point of inescapable singularity. A glowing ring orbiting the

## Physics Interactives

Welcome to Physics Interactives! This section of our website features a collection of HTML5 interactive pages that allow a user to explore a physics concept. Some Interactives are simulations that allow a user to manipulate an environment and observe the effect of changes in variables upon the simulation. Other Interactives are skill building exercises in which a user practices a skill that is crucial to learning some aspect of physics. And still other Interactives provide game-like environments that require the user to use a physics concept to meet a challenge. The Interactives are intended to be used by the individual student or learner who is attempting to further understand the concept or by a teacher-led classroom as part of a lesson or homework assignment. Most of the Interactives are accompanied by an activity sheet that suggests ways to use the widget.

Dolores Gende's insight:

We develop tasks in which students use data from contrasting cases to invent ratio or product quantities, rules or equations to characterize a variety of physical systems. Students work through sequences of such tasks to ramp up from everyday contexts to more abstract physics contexts.

## Blue Physics

Dolores Gende's insight:

Blue Physics by David Derbes is a free textbook (PDF), released under a Creative Commons license.

It is intended to be a "teach yourself" text for adults, covering first year college physics.
Knowledge of high school algebra is a prerequisite; calculus is taught as needed.
No prior knowledge of physics is presumed.

The book has many historical notes and worked examples. Internal references are hyperlinked.

## McCulley's HTML 5 Physics Lab Simulations

The simulations listed below are programs that I wrote for my students to use in lab as a complement to a live part of the lab. These programs were written to work on computers, tablets, phones and other handheld devices with HTML 5 capable browsers. All functionality for these programs comes from using the mouse or the touch screen an no keyboard usage is required.
