Explore the effect on spinning objects when the weight distribution or plane is changed. Recognize that angular momentum is conserved by an increase in the speed of rotation when the distribution of weight is closer to the center of mass. Details »
Classroom Resources
Experiment with various lengths of pendulums to derive the relationship between length and period of a pendulum's swing. Graph and analyze the data of the trapeze swing to recognize pendulum motions. Details »
Explore the concept of linear momentum and recreate the momentum transfer of the trapeze act from the video using skateboards. Calculate the momentum of marbles rolling down a ramp to verify the conservation of momentum. Details »
Design a virtual rollercoaster using Rollercoaster Tycoon and calculate the various g’s of the vertical and horizontal loops using the velocity and radius. Measure the centripetal acceleration acts of a spinning cork and analyze the data. Details »
Explore how energy is conserved and converted into different types of energy and analyze data from the circus. Build a marshmallow-launching machine whose energy only comes from a rubber band. Details »
