This video, entitled "Reflecting Angles," shows how angles can be reflected over a line of reflection.

A video entitled "Lines through the y-Axis" that covers writing equations of lines graphed on the coordinate plane.

Howcast - Learn what a personality disorder is from psychiatrist Ankur Saraiya in this Howcast video.

Howcast - Learn the single axis turn to the right and to the left from tango instructors Diego Blanco and Ana Padron in this Howcast Argentine tango video.

An investigation, carried out by the astrophysicists of the Instituto de Astrofísica de Canarias (IAC), questions one of the most interesting findings about the dynamics of the Milky Way in recent years: the precession, or the wobble in...

Pupil outcome: I can explain Earth’s movement and how the Sun gives us night and day and the seasons. Key learning points: - We have seasons because Earth is tilted on its axis as it orbits the Sun each year. - Each season has its own...

Pupil outcome: I can understand how Seneviratne uses structure and language to express ideas of time, identity and place in 'A Wider View'. Key learning points: - The structure of a poem arguably represents the journey of a concept or...

Pupil outcome: I can represent lengths and heights on a graph and use them to solve problems Key learning points: - Information about length and height from a table can be represented in a bar graph. - Information represented in a bar...

Pupil outcome: I can solve problems involving length. Key learning points: - Data can be collected to help solve a problem involving length. - When we collect data, we need to decide which units to measure in: mm, cm or m. - Representing...

Pupil outcome: I can explain why it is winter in the southern hemisphere when it is summer in the northern hemisphere. Key learning points: - In summer there are more daylight hours, compared to winter, the Sun appears higher in the sky...

This lesson explores the relationship between work done by torque and a body's rotational kinetic energy. It covers the application of the work-kinetic energy theorem for rotating bodies, explains how to calculate work done by constant...

This content explains the rotational dynamics of a judo foot-sweep, calculating the initial angular acceleration of an opponent. It analyzes the torques produced by both gravity and an applied pull, demonstrating how force placement and...

Explore how position and displacement vectors describe motion in two and three dimensions using i, j, k notation. Learn how to calculate vector differences and understand reference frames in kinematics

Explore the physics of a conical pendulum, where a bob moves in a horizontal circle forming a cone. Learn to analyze forces, derive equations, and calculate period and centripetal acceleration in circular motion

This content defines the total angular momentum (L) of a rigid body as the vector sum of the angular momenta of its constituent particles. It then extends Newton's Second Law to rotational motion, stating that the net external torque on...

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

In this video, we examine how the multiplicities of each zero (or factor) affects the graph of the polynomial function

In this video, we do a challenging distance formula problem. We find what point on the y axis would be equidistant from two given points.

In this video, we define reference angles, learn formulas for reference angles, and learn how to calculate reference angles. Personally, I focus more on visualizing the angle itself vs memorizing the formula

Watch this video to learn how to take equations written in standard form and write them in slope intercept form!

In this video, we examine a problem where we have to use the fact that parabolas are symmetrical in order to solve it.
