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

Which change would most likely increase the acceleration of a toy car?

Please select an answer first.

Correct answer: A

The correct answer is Increase the net force while keeping the mass the same..

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

A greater net force on the same mass produces a greater change in motion.

2. QuestionMultiple choice

What is a balanced-force situation?

Please select an answer first.

Correct answer: B

The correct answer is The net force is zero, so the objects motion does not change..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: Balanced forces cancel and do not produce acceleration.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

Balanced forces cancel and do not produce acceleration.

3. QuestionMultiple choice

Can an object move while the net force is zero?

Please select an answer first.

Correct answer: C

The correct answer is Yes, it can move at constant speed in a straight line..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: Zero net force means no change in velocity, not necessarily no motion.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

Zero net force means no change in velocity, not necessarily no motion.

4. QuestionMultiple choice

Which force usually slows a rolling ball on a floor?

Please select an answer first.

Correct answer: D

The correct answer is Friction.

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: Friction between the ball and floor opposes rolling motion.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

Friction between the ball and floor opposes rolling motion.

5. QuestionMultiple choice

How can a ramp change the motion of a cart?

Please select an answer first.

Correct answer: A

The correct answer is The ramp changes the direction of the gravitational component acting along the surface..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: The slope changes how gravity acts along the ramp and can affect the carts acceleration.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

The slope changes how gravity acts along the ramp and can affect the carts acceleration.

6. QuestionMultiple choice

A cart is pushed with 10 newtons right and 4 newtons left. What is the net force?

Please select an answer first.

Correct answer: B

The correct answer is 6 newtons to the right.

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: Opposite forces are subtracted: 10 newtons right minus 4 newtons left gives 6 newtons right.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

Opposite forces are subtracted: 10 newtons right minus 4 newtons left gives 6 newtons right.

7. QuestionMultiple choice

What would make a bicycle slow down more quickly?

Please select an answer first.

Correct answer: C

The correct answer is Applying the brakes increases friction between the brake parts and wheel..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: Brakes increase opposing force and reduce the bicycles motion.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

Brakes increase opposing force and reduce the bicycles motion.

8. QuestionMultiple choice

Which evidence shows that an object is accelerating?

Please select an answer first.

Correct answer: D

The correct answer is Its speed or direction changes over time..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: Acceleration is any change in velocity, including a change in speed or direction.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

Acceleration is any change in velocity, including a change in speed or direction.

9. QuestionMultiple choice

Why does a parachute slow a falling person?

Please select an answer first.

Correct answer: A

The correct answer is It increases air resistance opposing the downward motion..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: The parachute increases surface area and air resistance, reducing downward acceleration.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

The parachute increases surface area and air resistance, reducing downward acceleration.

10. QuestionMultiple choice

Which investigation best tests how surface type affects friction?

Correct answer: B

The correct answer is Pull the same block with the same force across different surfaces and compare its motion..

  1. Identify the motion concept: Determine the object motion, reference point, force, or data relationship described.
  2. Compare the forces or measurements: Changing one variable at a time makes it easier to compare the effect of surface type.
  3. Check the result: Use direction, time, distance, mass, friction, or net force to confirm the answer.

Changing one variable at a time makes it easier to compare the effect of surface type.
