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...

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...

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...

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...
