The students will design and build a vehicle that will be used in a variety of experiments in order to investigate forces. Discussion will revolve around what a force is, what different types of forces there are, and how they act on objects. An investigation of forces in this manner will allow students to gain knowledge of forces in a real and meaningful way. After gaining knowledge of forces, students will be asked to design and build an original vehicle that can be used in experiments involving increasing loads while being acted on by different forces.
