Why does it take Pluto 90,000 days to orbit the sun, but it only takes Mercury 88 days? An interactive lesson helps pupils find a connection between the speed of orbit and distance a planet is from the sun. The simulation allows for...

Can you time the speed of your car perfectly so you only hit green lights? The challenge in the simulation is to alter the timing of the lights or the speed of the car in order to do just that. Scholars learn about angular speed as they...

How do police determine the speed of a car that has hit a stopped vehicle? Scholars determine the momentum of the car system both before and after a collision. They identify instances where the law of conservation of momentum appears to...

Scholars must understand freefall before they learn how objects like airplanes fly. They apply knowledge of velocity and acceleration to predict speed and direction as part of a larger series on vectors and projectiles.

Increasingly, colleges and employers want applicants with strong conceptual analysis skills, so give them some practice! Applying these skills to position-time graphs encourages synthesis of knowledge. To complete an installment of a...

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...

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...

Cliff diving is more than an adrenaline rush ... it's a lesson in physics! Scholars adjust the height of a cliff and plot the resulting velocity and position over time on graphs. They also can incorporate air resistance to monitor 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...

Horizontal and vertical speeds change as projectiles move through space. As part of a series on vectors and projectiles, scholars create vector diagrams to compare these speeds at various locations. They they determine the values for...

Sometimes it appears that a bowling ball slides down the alley rather than rolling, while other times it appears to switch rolling directions at some point. Scholars control the bowling ball size, initial rotation, initial speed, and...

Tommy is stuck in a dungeon and can only escape if you can discover the correct formula for velocity! Through trial and error, scholars enter the velocity required for Tommy to reach the elevator at the proper time. Then they extrapolate...

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...

Study velocity while examining graphical representations. As scholars work with the animation, they discover the effect the height of an incline has on the velocity of the biker. They make conclusions about the slope of the...

In this AC waveforms learning exercise, students answer ten questions about AC voltage, frequencies of waveforms and they interpret diagrams of AC voltage.

For this house movement worksheet, students look at the gps website given and locate where their home may be and what climate change will take place in a million years. Students complete 9 questions.

Do you think you could fire an "unpowered" object into orbit? By controlling the angle and speed at which the satellite is launch, students will try to launch a satellite into space with this computer model. Activity includes questions...
