1. QuestionMultiple choice

What happens when the net force on an object is zero?

Please select an answer first.

Correct answer: A

The correct answer is Its motion does not change..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: A zero net force means balanced forces, so an object at rest stays at rest or a moving object keeps constant velocity.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

A zero net force means balanced forces, so an object at rest stays at rest or a moving object keeps constant velocity.

2. QuestionMultiple choice

A 4 kilogram object accelerates at 3 meters per second squared. What is the net force?

Please select an answer first.

Correct answer: B

The correct answer is 12 newtons.

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Use force equals mass times acceleration: 4 times 3 equals 12 newtons.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Use force equals mass times acceleration: 4 times 3 equals 12 newtons.

3. QuestionMultiple choice

Which change increases the gravitational potential energy of a box?

Please select an answer first.

Correct answer: C

The correct answer is Lifting the box to a higher shelf.

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Gravitational potential energy increases when an object is raised higher in a gravitational field.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Gravitational potential energy increases when an object is raised higher in a gravitational field.

4. QuestionMultiple choice

What happens to the kinetic energy of a moving bicycle when its speed increases?

Please select an answer first.

Correct answer: D

The correct answer is It increases..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Kinetic energy depends on motion and increases as speed increases.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Kinetic energy depends on motion and increases as speed increases.

5. QuestionMultiple choice

Which statement describes friction?

Please select an answer first.

Correct answer: A

The correct answer is It acts opposite the relative motion of contacting surfaces..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Friction resists sliding or attempted sliding between surfaces in contact.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Friction resists sliding or attempted sliding between surfaces in contact.

6. QuestionMultiple choice

A wave has a frequency of 5 hertz. What does this mean?

Please select an answer first.

Correct answer: B

The correct answer is Five complete waves pass a point each second..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Frequency measures the number of complete cycles that occur each second.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Frequency measures the number of complete cycles that occur each second.

7. QuestionMultiple choice

Which wave requires a medium to travel?

Please select an answer first.

Correct answer: C

The correct answer is A sound wave.

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Sound is a mechanical wave and needs particles in a medium to transfer the disturbance.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Sound is a mechanical wave and needs particles in a medium to transfer the disturbance.

8. QuestionMultiple choice

What happens when light reflects from a smooth mirror?

Please select an answer first.

Correct answer: D

The correct answer is It bounces off the surface..

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: Reflection is the change in direction that occurs when light bounces from a surface.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

Reflection is the change in direction that occurs when light bounces from a surface.

9. QuestionMultiple choice

Which circuit contains more than one path for electric current?

Please select an answer first.

Correct answer: A

The correct answer is A parallel circuit.

  1. Identify the science idea: Read the situation, model, or data carefully and identify the science concept being tested.
  2. Use evidence: A parallel circuit has branches, so current can travel along more than one path.
  3. Check the conclusion: Compare the answer with the evidence and confirm that the explanation matches the question.

A parallel circuit has branches, so current can travel along more than one path.

10. QuestionMultiple choice

What energy transformation occurs in a battery-powered flashlight?

Please select an answer first.

Correct answer: B

The correct answer is Chemical energy changes to electrical energy and then light energy..
