Concept-Development 6-4 Practice Page 1. The weight of the block is represented by vector W. We show axes parallel and perpendicular to the surface of the inclined plane. 2. W has a component parallel to the surface (bold vector). Acceleration down the incline is due to this component. 3. W also has a component perpendicular to the surface (bold vector). This compo-nent gives the force ...

5. Summarizing 2, 3, and 4, where the weight of one object causes the acceleration of two objects, we see the range of possible accelerations is (between zero and g) (between zero and inﬁ nity) (between g and inﬁ nity). 6. A ball rolls down a uniform-slope ramp. a. Acceleration is (decreasing) (constant) (increasing). b. If the ramp were ...

Concept-Development 34-1 Practice Page Electric Current 1. Water doesn’t ﬂ ow in the pipe when (a) both ends are at the same level. Another way of saying this is that water will not ﬂ ow in the pipe when both ends have the same potential energy (PE). Similarly, charge will not ﬂ ow in a conductor if both ends of the conductor are at the same electric potential. But tip the water pipe ...
