Using Parallax to Determine Distances

Does the mention of proteins and polypeptide relationships in your classroom result in mass confusion? Does the attempt to teach this important concept generate multiple questions and, at times, lead to a room filled with blank...

Parallax is the apparent change of an object determined by the line of sight. Sal defines the concept of parallax and applies it to how we determine the relative distance between us and nearby stars. He draws a diagram to illustrate what...

How can you determine the distance between two objects when one is incredibly far away? Discover how early astronomers and mathematicians calculated quantities such as the distance between Earth and the Sun in an insightful video. The...

As a follow-up to the Khan Academy video on parallax, this video focuses on parallax as it relates to astronomical distance. Sal uses cardinal directions and the seasons to help students orient themselves in the proverbial night sky....

A short clarification begins where the last video on stellar distance left off. It intends to clarify the trigonometry involved in using Parallax to determine stellar distance. The instructor uses the equations from the previous video to...

Displacement is a foundational concept for physics pupils. If they are having trouble discerning it from distance, this activity can help clear things up. The first page is essentially a piece of graph paper. It has a compass rose and a...

Scientists don't have a ruler long enough to measure to the stars, so they rely on math. Scholars learn to calculate the distance from Earth to a star using the parallax method. They use angle measures from different perspectives to...

This resource provides flexible alternate or additional learning activities for students learning about the concepts of distance, speed, and acceleration.

Explore the concept of projectile distance through determining the angle that will provide the maximum distance of a launched projectile.  Students launch baseballs on a football field and video tape the path of the ball.

Home is where your displacement is zero. Scholars practice solving distance versus displacement problems of increasing difficulty. They begin with two stage motion and, by the wizard level, each problem has four stage motion to consider....
