Forces and Motion Practice Tests

These Grade 7 Science practice tests build understanding of forces, net force, balanced and unbalanced forces, speed, velocity, acceleration, friction, gravity, mass, weight, and Newton's laws.

Skills covered

  • Describing motion with position, reference points, speed, velocity, and acceleration
  • Comparing balanced and unbalanced forces and determining net force direction
  • Explaining friction, gravity, air resistance, and normal force
  • Applying Newton's first, second, and third laws to everyday situations
  • Interpreting simple force, motion, and measurement scenarios

How to use these practice tests

For each question, identify the object and the forces acting on it. Then compare force directions and sizes before deciding whether the object remains at rest, moves at constant velocity, or accelerates.

1. QuestionMultiple choice

What is a force?

Please select an answer first.

Correct answer: A

The correct answer is A push or pull that can change an object's motion.

  1. Identify the motion idea: Determine whether the question asks about force, motion, speed, acceleration, mass, weight, or an interaction.
  2. Connect the evidence: A force is an interaction that can change speed, direction, or shape.
  3. Check the net effect: Compare the direction and size of forces to decide whether motion stays the same or changes.

A force is an interaction that can change speed, direction, or shape.

2. QuestionMultiple choice

Which unit is commonly used to measure force?

Please select an answer first.

Correct answer: B

The correct answer is The newton.

  1. Identify the motion idea: Determine whether the question asks about force, motion, speed, acceleration, mass, weight, or an interaction.
  2. Connect the evidence: Force is measured in newtons, while kilograms measure mass, meters measure length, and seconds measure time.
  3. Check the net effect: Compare the direction and size of forces to decide whether motion stays the same or changes.

Force is measured in newtons, while kilograms measure mass, meters measure length, and seconds measure time.

3. QuestionMultiple choice

What is motion?

Please select an answer first.

Correct answer: C

The correct answer is A change in position over time.

  1. Identify the motion idea: Determine whether the question asks about force, motion, speed, acceleration, mass, weight, or an interaction.
  2. Connect the evidence: An object is in motion when its position changes relative to a reference point over time.
  3. Check the net effect: Compare the direction and size of forces to decide whether motion stays the same or changes.

An object is in motion when its position changes relative to a reference point over time.

4. QuestionMultiple choice

What is a reference point?

Please select an answer first.

Correct answer: D

The correct answer is A location used to determine whether an object has changed position.

  1. Identify the motion idea: Determine whether the question asks about force, motion, speed, acceleration, mass, weight, or an interaction.
  2. Connect the evidence: Motion is described by comparing an object's position with a chosen reference point.
  3. Check the net effect: Compare the direction and size of forces to decide whether motion stays the same or changes.

Motion is described by comparing an object's position with a chosen reference point.

5. QuestionMultiple choice

What is the net force on an object?

Please select an answer first.

Correct answer: A

The correct answer is The combined effect of all forces acting on the object.

  1. Identify the motion idea: Determine whether the question asks about force, motion, speed, acceleration, mass, weight, or an interaction.
  2. Connect the evidence: Net force accounts for the size and direction of all forces on an object.
  3. Check the net effect: Compare the direction and size of forces to decide whether motion stays the same or changes.

Net force accounts for the size and direction of all forces on an object.

6. QuestionMultiple choice

What happens when equal forces act in opposite directions?

Please select an answer first.

Correct answer: B

The correct answer is The net force is zero..

  1. Identify the motion idea: Determine whether the question asks about force, motion, speed, acceleration, mass, weight, or an interaction.
  2. Connect the evidence: Equal opposite forces cancel, producing zero net force.
  3. Check the net effect: Compare the direction and size of forces to decide whether motion stays the same or changes.

Equal opposite forces cancel, producing zero net force.

7. QuestionMultiple choice

What happens when opposite forces are unequal?

Please select an answer first.

Correct answer: C

The correct answer is The net force points in the direction of the larger force..

  1. Identify the motion idea: Determine whether the question asks about force, motion, speed, acceleration, mass, weight, or an interaction.
  2. Connect the evidence: Unequal opposite forces produce a nonzero net force toward the stronger force.
  3. Check the net effect: Compare the direction and size of forces to decide whether motion stays the same or changes.

Unequal opposite forces produce a nonzero net force toward the stronger force.

8. QuestionMultiple choice

Which situation shows a balanced force?

Please select an answer first.

Correct answer: D

The correct answer is A book resting on a table with gravity balanced by the table's support force.

  1. Identify the motion idea: Determine whether the question asks about force, motion, speed, acceleration, mass, weight, or an interaction.
  2. Connect the evidence: Balanced forces produce zero net force, so the book remains at rest.
  3. Check the net effect: Compare the direction and size of forces to decide whether motion stays the same or changes.

Balanced forces produce zero net force, so the book remains at rest.

9. QuestionMultiple choice

Which situation shows an unbalanced force?

Please select an answer first.

Correct answer: A

The correct answer is A skateboard speeds up when a rider pushes backward against the ground..

  1. Identify the motion idea: Determine whether the question asks about force, motion, speed, acceleration, mass, weight, or an interaction.
  2. Connect the evidence: Speeding up means the object has acceleration, which requires a nonzero net force.
  3. Check the net effect: Compare the direction and size of forces to decide whether motion stays the same or changes.

Speeding up means the object has acceleration, which requires a nonzero net force.

10. QuestionMultiple choice

What can a net force change?

Please select an answer first.

Correct answer: B

The correct answer is An object's speed, direction, or shape.

  1. Identify the motion idea: Determine whether the question asks about force, motion, speed, acceleration, mass, weight, or an interaction.
  2. Connect the evidence: A net force can cause acceleration, change direction, or deform an object.
  3. Check the net effect: Compare the direction and size of forces to decide whether motion stays the same or changes.

A net force can cause acceleration, change direction, or deform an object.
