Big Challenge: Design and build a vehicle that will go straight, far, and fast, and carry a load. Students explore principles of motion and force, including relative motion, velocity, acceleration, Newton’s laws, friction, gravity, balanced and unbalanced forces, and net force. They use these principles to improve their design of two cars—one with and one without a propulsion system.
