Video describes what gravity is and how it operates between two masses. Followed by a short quiz and a list of additional resources to explore. [4:44]

This tutorial is intended for students to strengthen their understanding of gravitation and understand the nature of this force.

[Free Registration/Login may be required to access all resource tools.] Understand the role of gravity in space.

Video that uses an elevator in motion to describe the relationship among weight, gravity, and relative motion. [3:36] Includes a short quiz and a list of additional resources to explore.

In this video, Peter Bohacek explains the interplay between work and power and how it can be seen in the functioning of a clock. [4:31] Followed by a short quiz and a list of additional resources to explore.

Students defy gravity by stacking blocks in different ways in this exercise. Other projects are linked to this lesson as well.

This lesson focuses on the formation and life cycle of stars. Stars form when enough dust and gas clump together because of gravitational forces. Nuclear reactions release energy to keep the star hot. Some stars grow larger over time....

In this instructional activity we'll explore how we use fairly simple physics to draw particles which move according to the forces we feel in the real world (such as wind & gravity).

Electrical force between two electrically charged objects is inversely related to the distance between the two objects. Investigate why this becomes the inverse square law of physics. Engage in the Coulomb's Law interactive and check...

Through interactive practice problems and illustrated examples, students explore energy relationships for satellites.

As students begin to understand the physics behind thrust, drag, and gravity and how these relate these to Newton's three laws of motion, groups assemble and launch the rockets that they designed in the associated lesson.

Through ten lessons and numerous activities, students explore the natural universal rules engineers and physicists use to understand how things move and stay still. Together, these rules are called "mechanics." The study of mechanics is...

This lesson explains how gravitational force is related to free fall, acceleration due to gravity, and Newton's second law of motion.

In this two-part lesson, students will discover that no matter what the shape of the track, the marble will rise to the same vertical height. They will begin to understand the concepts of gravity, motion, and force.

Learners learn about the importance of dams by watching a video that presents historical and current information on dams, as well as descriptions of global water resources and the hydrologic cycle. Students also learn about different...

An introduction to the ideas behind the misconception and misunderstanding of why all objects accelerate at the same rate. This explanation involves the concepts of force and mass.

Through eight lessons, students are introduced to many facets of dams, including their basic components, the common types (all designed to resist strong forces), their primary benefits (electricity generation, water supply, flood...
