Look at the diagram of the roller coaster. Evaluate the relative potential energy at points 1-4. The height is in meters (m), Which two statements correctly describe the relative potential energy at various points on the track?

• At (1) the potential energy is greater than the potential energy at (3)

• At (2) the potential energy is greater than the potential energy at (3)

• At (3) the potential energy is greater than the potential energy at (4)

• At (4) the potential energy is greater than the potential energy at (2)

Answer explanation

At (1) and (2), the potential energy is higher than at (3) and (4), making the statements 'At (1) the potential energy is greater than the potential energy at (3)' and 'At (2) the potential energy is greater than the potential energy at (3)' correct.

Design a project to compare the effects of physical changes (such as temperature and pressure) on different states of matter.

• Heat and cool water, ice, and steam to observe changes in state and record temperatures at which these changes occur.

• Freeze and melt different metals to see which one has the highest melting point.

• Apply pressure to various solids to determine their hardness.

• Observe the color changes in substances when heated without measuring temperature.

DOK Level 4: Extended Thinking

Nathan lost his balance when he hit the bag with a hard punch. He says that was because of the reaction force from his punch, which was large because the bag is heavy. Is he correct?

• Yes, he is correct.

• No, it is not the weight, it is the large mass of the bag that gives the large reaction force.

• No, the reaction force depends on the force of Nathan's punch, not on the mass of the bag.

• No, the bag does not exert a reaction force, because it is flexible.

Answer explanation

The correct choice is 'No, the reaction force depends on the force of Nathan's punch, not on the mass of the bag.' The reaction force is determined by the force applied, not the mass of the bag.

A student conducts 5 trials to investigate factors affecting the formation of impact craters and here are the results. Which statement BEST describes the results of the investigation?

• The kinetic energy of the marble just before impact is proportional to the depth of the crater it forms

• The kinetic energy of the marble just before impact is proportional to the mass of the marble

• The depth of the crater is proportional to the mass of the marble

• The depth of the crater is proportional to the mass of the marble

Answer explanation

The kinetic energy of the marble just before impact is proportional to the depth of the crater it forms
