Serc: Hand Towing a Car: Critical Thinking, Problem Solving and Analysis
In this active learning activity, students will find a technique to move a car with one hand. Students are given only a tow strap, so the students must apply angular force to successfully move the car with one hand.
Physics Aviary
Physics Aviary: Practice Problems: Net Torque Level 1
Students must determine the net torque on a wheel. There will be four forces on the wheel and all of them will be at right angles to the radius from the center of the wheel.
Physics Aviary
Physics Aviary: Practice Problems: Net Torque Level 2
Students must determine the net torque on a wheel. There will be two forces on the wheel that will be apply at random angles to their radii.
