Go to the roller coaster simulation and click on the "launch" button. pay attention to the pie chart as the roller coaster moves and fill in the blank. be sure to keep this website open because there will be several questions related to it.

the kinetic energy the roller coaster goes downhill.

click the "step" button on the simulation to observe the energy at different points on the roller coaster ride.

kinetic energy is greatest
potential energy is greatest at
kinetic energy is decreasing while potential energy is increasing between

which chart comes closest to the relationship between kinetic energy and potential energy at point 6?
increases
point 2
point 1
3 and 4
the middle one

Follow these directions and answer the questions. 1. set up the ripple tank as in previous investigations. 2. bend the rubber tube to form a "concave mirror" and place in the ripple tank. the water level must be below the top of the hose. 3. generate a few straight pulses with the dowel and observe the reflected waves. do the waves focus (come together) upon reflection? can you locate the place where the waves meet? 4. touch the water surface where the waves converged. what happens to the reflected wave? 5. move your finger twice that distance from the hose (2f = c of c, center of the curvature) and touch the water again. does the image (the reflected wave) appear in the same location (c of c)? you may have to experiment before you find the exact location. sometimes it is hard to visualize with the ripple tank because the waves move so quickly. likewise, it is impossible to "see" light waves because they have such small wavelengths and move at the speed of light. however, both are examples of transverse waves and behave in the same way when a parallel wave fronts hit a curved surface.

Work = force × a. work b. energy c. distance d. momentum

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?
