Visualize the gravitational force that two mass spheres exert on each other. Move spheres in meters, change mass in kilograms, and observe changes to the gravitational forces that m1 and m2 exert on each other.

Introduces caveman Zog to Newton's basic laws of motion. By observing objects on earth and in space, Zog learns that nothing can start moving, speed up, slow down, change direction, or stop unless a force is applied to it--even if the force is hard to see, like gravity or friction. He learns that for every force there is an equal and opposite force and that is the principle behind jet propulsion. And he learns that, scientifically, work occurs only when a force moves an object some distance.

Visualize the gravitational force that two objects exert on each other. Discover the factors that affect gravitational attraction, and determine how adjusting these factors will change the gravitational force.
This video discusses the principle of force and the application of Newton's three laws of motion. Through the use of real-world examples, students will witness the effect of friction on force. Other topics covered include inertia, weight, mass, gravity, and the law of universal gravitation.
Presents three key physics concepts about force and motion: constant speed, acceleration, and gravity and falling. Each concept is illustrated with a variety of experiments and computer animation to illuminate what is happening both visibly and at the molecular level.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term force. Part of the Science Video Vocab Series.

Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term balanced force. Part of the Science Video Vocab Series.

An early exploration (2015) into how to make a sim accessible has taken place for Forces and Motion Basics. It has working keyboard navigation and auditory descriptions for the 'Net Force' screen when the screen reader is in 'Forms' mode. We are working on updating the content so that it can be read by the screen reader in any mode. Notes for the main interaction: Press 'Enter' or 'Spacebar' to enter a group of pullers. Once in the group, use 'Arrow' keys to choose which puller you wish to select. Press 'Enter' or 'Spacebar' to select puller and move to knot selection. Use 'Arrow' keys to choose between different knots. Press 'Escape' to leave a group of pullers or knots, 'Tab' to leave group and go to next element. This prototype has been tested with NVDA and Firefox.
Students explore the characteristics of fluids. Some topics they study include pressure and its impact on the behavior of fluids, Bernoulli’s and Pascal’s principles, and density and its effect on buoyancy. Additional concepts and terminology discussed include: hydraulic devices, particles, differences in pressure, air pressure, and buoyant force.
Through observation and experimentation, students will learn properties of forces, Newton’s Laws of Motion, and how pressure affects the world. Real world examples encourage students to explore their surroundings and to discover the impact forces have on everyday life. Part of the Real World Science series.
To change a spacecraft's speed and direction, NASA engineers use a planet's or moon's gravity, a process called a "gravity assist." In this video, students design and build systems that use magnets to control the speed and direction of a rolling ball. As they build their systems, they use the engineering design process, apply a variety of science concepts, and learn how NASA spacecraft use gravity to help them explore the solar system. Part of the "Design Squad Nation" series.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term unbalanced force. Part of the Science Video Vocab Series.
Gravity and erosion are major factors in changing the shape of the surface of Earth. The different types of erosion and the effect of gravity on objects is discussed in this video. Other topics covered include folding, faulting, deposition, creep, mass movement, landslide, surface runoff, alluvial fan, delta, stream erosion, beach erosion, ice erosion, wind erosion, dune, glaciers, and glacial deposits.
A Category 5 hurricane is a monster of a storm that most people would want to avoid. But, Civil Engineer Arindam Chowdhury actually recreates those monster hurricane force winds in hopes of helping people better prepare for the real thing. With support from the National Science Foundation, Chowdhury and his team at Florida International University and the International Hurricane Research Center designed a 15 foot tall Wall of Wind (WOW). The goal is to see if low rise structures and building materials can withstand the same wind forces they would face in a full-blown hurricane. Part of the National Science Foundation Series “Science Nation.”
In a tsunami, devastation is created by far more than the wave itself. Debris that hits homes and other structures plays a huge role in a tsunami’s destructive power. But until now, engineers could only estimate the forces at work when debris, such as a floating telephone pole, hits a house. With support from the National Science Foundation, engineers from across the country have teamed up to design and carry out a series of large-scale tests aimed at better understanding exactly what happens when debris strikes. Part of the National Science Foundation Series “Science Nation.”
