Grade 6 Forces and Motion Practice Test

Build Grade 6 Science skills with five 10-question practice tests on motion, speed, forces, net force, friction, gravity, mass, weight, and Newton laws.

Forces and Motion Practice Tests

These Grade 6 Science practice tests help students describe motion and explain how forces change it. Students practice reference points, distance, time, speed, pushes and pulls, net force, balanced and unbalanced forces, friction, gravity, mass, weight, inertia, and Newton laws.

Skills covered

  • Describing motion using position, distance, time, and reference points
  • Calculating and comparing simple speeds
  • Identifying contact and noncontact forces
  • Determining net force and balanced or unbalanced conditions
  • Explaining friction, gravity, mass, and weight
  • Applying basic ideas from Newton laws to everyday situations

How to use these practice tests

For motion questions, identify the reference point and compare distance with time. For force questions, include direction and compare the sizes of opposite forces. Remember that a net force of zero can describe an object at rest or moving at constant speed, while a nonzero net force changes motion.

1. QuestionMultiple choice

What does Newtons first law describe?

Please select an answer first.

Correct answer: A

The correct answer is An object tends to keep its motion unless an unbalanced force acts on it..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: The first law describes inertia, the tendency to resist changes in motion.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

The first law describes inertia, the tendency to resist changes in motion.

2. QuestionMultiple choice

What is inertia?

Please select an answer first.

Correct answer: B

The correct answer is The tendency of an object to resist a change in its motion.

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: Objects with more mass generally have more inertia and are harder to accelerate or stop.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

Objects with more mass generally have more inertia and are harder to accelerate or stop.

3. QuestionMultiple choice

Why does a passenger move forward when a bus stops suddenly?

Please select an answer first.

Correct answer: C

The correct answer is The passengers body tends to keep moving forward because of inertia..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: The passengers body continues its previous motion until a force changes it.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

The passengers body continues its previous motion until a force changes it.

4. QuestionMultiple choice

What does Newtons second law connect?

Please select an answer first.

Correct answer: D

The correct answer is Force, mass, and acceleration.

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: The second law explains that a greater net force can produce greater acceleration, while greater mass resists acceleration.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

The second law explains that a greater net force can produce greater acceleration, while greater mass resists acceleration.

5. QuestionMultiple choice

What happens when the same force acts on two objects with different masses?

Please select an answer first.

Correct answer: A

The correct answer is The object with less mass generally accelerates more..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: For the same net force, less mass results in a greater change in motion.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

For the same net force, less mass results in a greater change in motion.

6. QuestionMultiple choice

What does Newtons third law state?

Please select an answer first.

Correct answer: B

The correct answer is For every action force, there is an equal and opposite reaction force..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: Forces come in pairs acting on different objects.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

Forces come in pairs acting on different objects.

7. QuestionMultiple choice

Why does a swimmer move forward when pushing water backward?

Please select an answer first.

Correct answer: C

The correct answer is The water pushes the swimmer forward with an equal and opposite force..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: The swimmers backward push on water produces a forward reaction force from the water.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

The swimmers backward push on water produces a forward reaction force from the water.

8. QuestionMultiple choice

What happens when a person pushes against the ground while jumping?

Please select an answer first.

Correct answer: D

The correct answer is The ground pushes the person upward..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: The upward reaction force from the ground helps launch the person.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

The upward reaction force from the ground helps launch the person.

9. QuestionMultiple choice

Which situation shows Newtons first law?

Please select an answer first.

Correct answer: A

The correct answer is A hockey puck stays at rest until a stick applies an unbalanced force..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: The puck remains at rest until an external unbalanced force changes its motion.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

The puck remains at rest until an external unbalanced force changes its motion.

10. QuestionMultiple choice

Why are seat belts important during a sudden stop?

Please select an answer first.

Correct answer: B

The correct answer is They provide a force that changes a passengers forward motion..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: The seat belt helps stop the passenger with the vehicle instead of allowing continued forward motion.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

The seat belt helps stop the passenger with the vehicle instead of allowing continued forward motion.
