This activity complicates the physics of motion by adding the forces of gravity and friction to the mix. Students use stiff cardboard to build a ramp that will form the arena for the exercise. After measuring the ramp's dimensions, they allow a toy dump truck to descend the ramp and reco...

Unit 4: Forces and Motion (Chapters 5, 6 and 7) Test Study Guide KEY Unbalanced forces always cause change in speed, direction or both. Car tires moving a car forward is one activity in which friction is helpful. Friction occurs because of the roughness of any object’s surface. Because...
Inertia, Motion and Forces Why are seat belts a good idea? Inertia, Motion and Forces What forces act upon this person during a car accident? A force is a push or a pull What is force? A force is a push or a pull It can change the movement of an object Sometimes forces are obviou...

These methods, however, inform poorly on timescales. Neutron scattering is well ...
The considered hulls are fast slender displacement type with transom stern and L/B ratios 14, 12, 8. The most slender hull is a trimaran main hull, the second one is a catamaran demihull and the last one is the Model 5 (Blok and Beukelman, 1984). The calculations were performed using...
