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...

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...

Why do many tightrope walkers use a balancing pole? The simulation explores the benefits of balancing poles and the features that are most important. Pupils control the pole length, pole mass, pole stiffness, and the initial angle of...

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...

Acceleration, velocity, mass, and gravity all play a role in the motion of a rocket. Young scientists explore the connection among these components using an interactive tutorial. They adjust the mass and thrust force to experiment with...

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...

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...

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...
