Writing Equations of Parallel and Perpendicular Lines
In this video lesson we will learn how to identify if two lines are parallel and if two lines are perpendicular to each other. We will discover that parallel lines have the same slope. We will learn that perpendicular lines have slopes...

When a chord is bisected by a line then it is perpendicular to that line
Learn how to solve problems with chords. A chord is a line that has its two endpoints on the circle. A chord passing through the center of the circle is refered to as the diameter of the circle. A chord divides the circle into two...

Understanding Parallel, Intersecting, and Perpendicular Lines
In this video, students will learn about parallel, intersecting, and perpendicular lines. They will understand that parallel lines never intersect and are always the same distance apart, while intersecting lines pass through the same point.

Moments _ GCSE Physics
A moment is the turning effect of a force. It’s calculated by multiplying the force by the perpendicular distance between the force and the pivot. For example, by turning a spanner you are producing a moment. If you apply a force of 15N...
