Third graders will observe and analyze the forces of gravity.

Learn about the force of gravity in this article. Also, view a video that shows angry birds and pigs go weightless!

In the following lesson students will learn about center of gravity and how the body adjusts to the force of gravity to remain balanced.

[Free Registration/Login may be required to access all resource tools.] Using Newton's Law of Gravity and the equations of uniform circular motion, students solve problems involving the force of gravity.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will learn to describe and calculate how the magnitude of the gravitational force between two objects depends on their masses and...

Descriptions of an experiment performed by geologists to determine the Newtonian constant of gravity, or "G". Highly sophisticated reading.

Students describe and create an experiment to prove that like poles of magnets repel each other while opposite poles attract. Using the experiment, they use the data to support the claim that the repelling force is stronger than the...

You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of...

This mini lab was designed to visually illustrate the relationships between the force of gravity and the factors that determine its strength.

An equation for the law of universal gravitation is stated. The weight equation (W=m*g) is related to the law. An interactive JavaScript form allows the user to practice determining the force of gravity and the acceleration of gravity...

A learning module reviewing how much force is needed to push or pull objects. Also learn about the force of gravity.

Students explore the physics utilized by engineers in designing today's roller coasters, including potential and kinetic energy, friction, and gravity. First, students learn that all true roller coasters are completely driven by the...

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]

[Free Registration/Login may be required to access all resource tools.] Discusses the force of gravity and how it affects our lives.

Using this interactive resource will involve making predictions about the effects of gravity in different conditions.

An interactive simulation that teaches about gravitational force, circular motion, and astronomy by manipulating the sun, earth, moon, and a space station to observe the effects of gravity and orbital paths. This simulation can either be...

In this physics interactive lecture demonstration, students will predict what will happen if a plastic bottle, filled with water and having a hole near the bottom, is dropped. Will the bottle fall at the same rate as the water inside the...

Several diagrams provide explanations of planetary gravity as well as the gravity that exists between all objects.

Our bodies function necessarily under the presence of gravity; how blood pumps, a sense of balance and bone growth are all due to life in a world where gravity is an inescapable reality. Armed with experiments from neuroscientists David...

Use water balloons to show the effect gravity will have on different sizes of objects in our solar system. Activity also shows how inertia works.

Students investigate how the force of gravity varies with location on Earth. They are challenged to find the pattern in their findings.

A very detailed look at gravitational force and the many theories that have been put forward to try to explain it. Includes lots of illustrations.

[Free Registration/Login may be required to access all resource tools.] Definition of gravity and how it relates to weight. Includes a video. [3:54]

The application of engineering principles is explored in the creation of mobiles. As students create their own mobiles, they take into consideration the forces of gravity and convection air currents. They learn how an understanding of...
