First, science teaching should provide more concrete learning experiences, which are related to familiar situations and interactive, in order to support conceptual change. Most conventional physics courses, for example, focus on manipulating mathematical expressions that refer to idealized situations, i.e. a frictionless plane.

Static friction is the force responsible for holding an object in place. In order for an object to move, the applied force must overcome the force of static friction. Our lab uses the force of gravity in order to find the maximum static friction force on an object before it turns into kinetic friction. This will help in the

Feb 04, 2013 · Figure 5-4 shows a cart of mass m moving to the right on a frictionless air track under the action of a constant net force, F. Because the force is constant, we know from Newton's second law that the particle moves with a constant acceleration, a. While the force is applied, the cart accelerates from an initial velocity v-% to a final velocity Vf.
