A student creates this model using a rope between two students to show energy moving through a system: Student A moves the rope while Student B holds their end steady. Which statement best explains how this model shows energy transfer?

• The energy causes each part of the rope to move up and down as it travels from Student A to

  Student B

• The energy makes the rope move sideways toward Student B.

• The energy stays only where Student A moves the rope.

• The energy makes the rope stretch longer.

Which diagram shows a longitudinal wave?

• Top diagram because the coils move back and forth in the same direction as the wave

• Bottom diagram, because the coils move back and forth in the same direction as the wave

• Bottom diagram, because the coils move up and down perpendicular to the wave direction

A student observes a small cube floating on water to show how energy moves through the system: Select TWO statements that correctly explain how this model shows energy transfer.

• The energy only works when the cube moves up.

• The cube moves up and down as energy passes through the water.

• The energy moves through the water while making the cube move up and down.

• The cube stays in one spot on the water.

A student creates a model using a slinky. Points a, b, and c are marked along the slinky as shown: How will point b move when energy passes through this point in the system?

• Forward along the slinky

• In circles

• Up and down while energy moves through

• Remain still

Which type of wave is this model demonstrating?

• A longitudinal wave because the dominoes move up and down as they fall.

• A transverse wave because the energy moves forward as dominoes push in the same direction.

• A longitudinal wave because the energy moves forward as dominoes push in the same direction.

• A transverse wave is caused by the dominoes moving up and down as they fall.
