This list of products is composed of items that are used repeatedly throughout the Conceptual Physics Lab Manual and should be ordered as needed based on the number of students or lab groups in your classroom.

Conceptual Physics chapter demos for teachers discussing projectile motion, non-linear motion, friction and air resistance.

Measuring Constant Velocity- A moving object experiences a change in its position in a certain time. For constant velocity, the change in position over each equivalent time period is constant. Students will graph the position vs. time of a moving car. The graph will be a straight line whose slope is the car’s velocity.

Science students: Start your engines! “When I pull out the constant velocity cars, I usually hear a chorus of, ‘All right!’ from the class. That's what I think, too, because these powerful miniature dune buggies are so effective at helping my students really grasp what constant motion is and how to graph it.

In this experiment, you will plot a graph that represents the motion of an object. Sometimes two quantities are related to each other, and the relationship is easy to see. Sometimes the relationship is harder to see. In either case, a graph of the two quantities often reveals the nature of the relationship. In this experiment, students will plot a graph that represents the motion of a real object.

Lab # 2.1   Mechanics:  Walking the Plank
Purpose
In this activity, students will measure and interpret the forces acting on an object when the object is in equilibrium.
Discussion
Consider two sign painters who work on a scaffold (a plank of wood suspended by ropes at both ends). They might wonder about the tension in the ropes that support [...]
