Does size or mass impact gravitational pull? Scholars experiment with force pairs to answer that question. They can change the size, mass, and distance between the objects using an engaging simulatoin. This allows pupils to visualize the...

Scientists state that the higher something is above the earth, the greater the gravitational potential energy. Does this mean there is more gravity acting on the moon than on an apple falling from a tree? Scholars adjust the distance...

Blast off! How do satellites, space shuttles, and space stations escape Earth's gravity and achieve orbit? Young astronauts study rocket science (literally) with an interactive lesson. They discover the four main uses for satellites, how...

Gravity does more than keep our feet on the ground — it holds a satellite in orbit, too. Help learners understand the effects of gravity on an orbiting object through a simulation activity. Individuals adjust a launch speed and watch as...

Are you feeling weighed down by your current gravitation presentation? Assign a hands-on interactive instead! Physics scholars work through a series of progressively harder questions about mass, distance, and gravity using an online...

How does an airplane control its take off and descent? Scholars explore the forces acting on an airplane and control the angle of attack, wing profile, thrust, and airplane size. They learn about lift, drag, thrust, gravity, and the...

Everything that happens is an interaction, from the wind blowing a sail to a cannon ball being thrust out of a cannon. A simulation shows the interactions involving a sail, air, ball, pirate, cannon, deck, ocean, and the Earth and...

We can't see most gases and we can't see things at the molecular level — but that's about to change! A simulation shows pupils the activity of molecules in a gas. The simulation allows scholars to vary the volume, heat, and...

To show the magnitude and direction of all forces acting upon an object, scientists use a free body diagram. This simulation serves as an introduction to free body diagrams allowing scholars to build their own. Pupils select the proper...

In this law and lore worksheet, students choose the correct word to complete each sentence. Students choose either law or lore for 10 sentences.

For this energy, work and power worksheet, students solve 12 problems about circuits, electric motors, Ohm's Law and electric currents.

[Free Registration/Login Required] Learn about the universal law of gravity and the role Newton played in relating terrestrial and celestial mechanics to one another.

An early astronaut's experiences teach students that Newton's third law of motion-for every action, there is an equal and opposite reaction-applies both on Earth and in outer space.

Design your own virtual rocket, and then test launch it. Watch tutorials about Newton's laws of motion and rocket basics to help you improve your rocket's performance.

From the Exploratorium Museum. Includes an interactive feature in which a visitor enters their weight on earth and has their weight on other planets computed and displayed. Discusses the distinction between mass and weight and describes...

[Free Registration/Login Required] Test your knowledge of Newton's Law of Universal Gravitation with an animation and a short quiz.

Have you ever felt that queasy feeling in a moving elevator? Explore the physics behind the sensations of weightlessness and weightiness. Teacher notes and a downloadable handout are also provided.

Use this interactive, animated lab to explore conservation of mechanical energy.

Kepler's second law of planetary motion is stated and explained. An animation of the orbit of a planet and an accompanying graphic assists in explaining the meaning of the law of equal areas.

Students discover the Law of Universal Gravitation by changing the masses of planets and moons and the distance that separates them.

Manipulate the mass and distance of two objects to see how these properties change the gravity force.

This lab was designed to allow students to collect data for the force between two objects in deep space. The students are transported by TARDIS to deep space and can use force probes to measure the pull between two objects. Students can...

[Free Registration/Login Required] Learn about orbits and how an object can stay in orbit under the influence of gravity. By adjusting launch velocities users will understand how to successfully put a virtual satellite into orbit without...

A science simulation launches a projectile from the top of a mountain testing Newton's theory introduced in Principia.
