Unicycle
What is the steepness of a hill before a unicyclist slides down it rather than pedaling down it? The simulation graphs the wheel speed versus the unicycle speed as the rider goes down a hill. Scholars control the mass of the rider,...

Orbital Motion
Why do planets orbit the sun in ellipses when moons orbit their planet in circles? Pupils control the semi-major axis, eccentricity of the orbit, and position angle. The resulting orbital appears with the related force vectors as...
CK-12 Foundation
Ramp and Piano
Can you lift a piano into a truck? Simulation allows scholars to explore the relationship between force, ramp length, and weight. Pupils control the variables of truck bed height, ramp length, weight of piano, and the number of friends...

Collisions
Is momentum conserved in a collision, along with energy, or are they opposing forces? Pupils vary the mass and velocity of two bumper cars along with the type of bumper in order to answer this question. Worksheet and in-simulator...
CK-12 Foundation
Bumper Cars
Is the transfer of energy different in bumper cars with stable versus bouncy bumpers? One of the variables explored in the simulation is bumper type; other variables are the mass and velocity of each car. This allows pupils to see the...
CK-12 Foundation
Crash Test Dummy
Why are car manufactures required to install seat belts and airbags; do they really make that big of a difference? Scholars use a simulator to determine the amount of force dissipated by a seat belt and airbag in a head-on crash. This is...

Journey to Mars
Why are there launch windows when traveling to outer space? Scholars explore the trajectory of traveling from one planet to another. By adjusting the departure and destination planets, as well as the launch date, they observe the ideal...

Newton's Apple
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...

Clarke's Dream
How does satellite TV keep a steady stream when the earth and the satellite are constantly moving? Scholars use a simulator to adjust the radius of orbit of a satellite around the earth. They view graphs of acceleration and time period...
CK-12 Foundation
See Saw
Can a mother who weighs five times more than her child really be held in the air on a see saw by the child? A simple simulation demonstrates how this is possible through altering the distance from the fulcrum. Scholars can adjust the...
CK-12 Foundation
Wind Turbine
Scientists know wind is a renewable resource, but is it an efficient one? Scholars adjust the propeller diameter on a wind turbine, the wind speed, and the conversion efficiency within range to learn about the efficiency of these...
CK-12 Foundation
Tetherball
What forces are at work when playing tetherball? Using a simulator, pupils control the ball mass, tether length, and ball speed to better understand the physics of the game. A worksheet and challenge questions reinforce the concepts...
CK-12 Foundation
Phases of the Moon
The sun can tell us what time it is with a sun dial, but can the moon do the same? Scholars play with a simulation of the phases of the moon. They control the type of moon and time of day in order to see when the sun is up and when the...

Water Fountain
Most water fountains are designed to keep the water inside the fountain, but how are they designed to shoot up and out without the water leaving the fountain? Scholars vary the launch angle, fountain height, launch speed, and...
CK-12 Foundation
Horse and Cart
Can a horse pull more than its weight? A simple simulation answers this question and more. Pupils adjust the mass in a cart, the mass of the horse, the acceleration of the horse, and the angle of the tension rope between the horse and...
CK-12 Foundation
Sprinter
Why do sprinters wear spiked shoes? Scholars explore various styles of shoes and how they handle forces when running. Scholars adjust variables including shoe type, horizontal force, surface type, and normal force to determine which...
CK-12 Foundation
Elevator
Do you weigh slightly less when an elevator first starts its descent? The simulation teaches the change in the force based on the acceleration, constant speed, or deceleration of an elevator. Scholars control the mass and acceleration...
CK-12 Foundation
Everglades Airboat
How does an airboat move when there isn't a motor in the water? The simulation teaches the forces related to the thrust and drag on an airboat. Scholars vary the boat mass and thrust force in order to view graphs of the changing force...
CK-12 Foundation
Pirate Ship
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...
