Set youngsters in motion when studying forces. This quick animated film stars Sam and Mia, two intelligent but cool kids who talk about forces and motion on the soccer field. Consider using this resource when preparing junior-high...

How is tug of war related to pushing a refrigerator? Here's a simulation connects these two activities with Newton's First Law of Motion. Four different simulations allow scholars to explore net force with tug of war, motion with pushing...

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...

Keep calm and use the force! Joey pulls a cart and scholars adjust the force required to control the movement. Through simulating different scenarios, participants learn about Newton's Third Law. It includes analysis questions throughout...

Does Newton's First Law of Motion explain how to move a sled across ice? A simulation encourages scholars to decide if they should push, pull, or apply no force. Their decision moves a sled across the ice and to the home at the...

Become a pinball wizard by understanding acceleration. Mia and Sam define acceleration for the audience and touch on the property of inertia. Get your physical science class up to speed by showing this little video, reviewing the...

Explore the forces at work when you try to push a filing cabinet. Create an applied force and see the resulting friction force and total force acting on the cabinet. Charts show the forces, position, velocity, and acceleration vs. time.

Explore the forces at work when pulling against a cart, and pushing a refrigerator, crate, or person. Create an applied force and see how it makes objects move. Change friction and see how it affects the motion of objects.

See how forces affect various items that are pushed or pulled.

Use this simulation to see the results of applying a force to move an object. Analyze forces and friction using graphs.

Use your knowledge about friction to help Carrie get to the Invigatron before someone steals it. Following the activity, read more about friction and resistance, and then take a quick quiz to check for understanding.

An interactive playground for students to explore the physics of roller coasters. Learners investigate by changing the variables of force, velocity, friction, and vectors. Energy bar charts are displayed as the coaster car moves along...

[Free Registration/Login Required] Use given friction formulas and an interactive diagram for an inclined plane to solve a motion problem. After the activity, answer a challenge question to check for understanding.

This site is an interactive app of an inclined plane showing the effect of the angle, the weight of the block, and the friction as a block is pulled up an incline.

Experience the effect of friction, air resistance, and applied force upon a sledder. The speed, acceleration, and force values are displayed as the sled moves. Learners can vary the mass of the sledder and the size of the parachute...

This interesting and interactive exhibit demonstrates how Newton's Laws of Motion impact the design and safety of roller coasters.

An interactive tool where students can explore how a spring behaves, and how changing the elasticity, mass, push/pull force, and friction affect its motion or period. As the spring moves, its motion is shown on a distance-time graph.

Visit this summary of friction. Use the interactive JAVA window to run friction simulations.

Observe how friction affects a mass connected to two springs that are on opposite sides of the mass. Create a graph while the friction is on or off.

Watch how the placement of two weights attached to a chain on different sides of a pulley affect the movement of the system. You can adjust the heaviness of the weights.
