1. QuestionMultiple choice

A soccer ball speeds up after a player kicks it. What caused the change in motion?

Please select an answer first.

Correct answer: A

The correct answer is An unbalanced force acted on the ball..

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: A kick applies a net force that changes the balls motion, so the forces are unbalanced.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

A kick applies a net force that changes the balls motion, so the forces are unbalanced.

2. QuestionMultiple choice

Which surface would create the greatest friction for a sliding block?

Please select an answer first.

Correct answer: B

The correct answer is A rough rubber mat.

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: Rough surfaces generally create more friction than smooth surfaces.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

Rough surfaces generally create more friction than smooth surfaces.

3. QuestionMultiple choice

A book rests on a table. Which statement best describes the forces on the book?

Please select an answer first.

Correct answer: C

The correct answer is Gravity downward and the table force upward are balanced..

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: The table pushes upward while gravity pulls downward with equal forces, so the book remains at rest.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

The table pushes upward while gravity pulls downward with equal forces, so the book remains at rest.

4. QuestionMultiple choice

A skateboarder starts at the top of a hill and rolls downward. What energy change occurs?

Please select an answer first.

Correct answer: D

The correct answer is Gravitational potential energy changes into kinetic energy..

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: As height decreases and speed increases, gravitational potential energy is transferred to kinetic energy.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

As height decreases and speed increases, gravitational potential energy is transferred to kinetic energy.

5. QuestionMultiple choice

Which force keeps a satellite moving around Earth instead of traveling in a straight line?

Please select an answer first.

Correct answer: A

The correct answer is Gravity.

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: Earths gravitational attraction continually changes the satellites direction.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

Earths gravitational attraction continually changes the satellites direction.

6. QuestionMultiple choice

Two carts have the same mass. Cart A is pushed with twice the force of Cart B. How will their accelerations compare?

Please select an answer first.

Correct answer: B

The correct answer is Cart A will have greater acceleration..

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
  2. Use evidence from the model or investigation: With mass held constant, a greater net force produces a greater acceleration.
  3. Check the conclusion: Confirm that the answer matches the evidence and the scientific relationship in the Hawaii Grade 8 Science assessment task.

With mass held constant, a greater net force produces a greater acceleration.

7. QuestionMultiple choice

What does mass measure?

Please select an answer first.

Correct answer: C

The correct answer is The amount of matter in an object.

  1. Identify the Grade 8 science concept: Determine whether the task uses forces, energy, waves, life science, Earth systems, climate, data, or engineering.
