PSEB Class 9 Force and Laws of Motion Practice

Force and Laws of Motion is an important Class 9 Science chapter that explains how force changes the state of rest or motion of an object. Students learn the difference between balanced and unbalanced forces, the meaning of inertia, and the three laws of motion given by Newton.

Questions from this chapter may ask students to identify examples of inertia, explain Newton's first, second and third laws, calculate momentum using p=mv, calculate force using F=ma, and understand action-reaction pairs, recoil and conservation of momentum.

Use this 20-question practice test before broader Class 9 Science revision. After completing the test, review every explanation carefully and repeat the test after revising weak areas such as inertia, momentum, force calculations, Newton's laws, and conservation of momentum.

What to Review for Force and Laws of Motion

Focus on force, inertia, Newton's laws, momentum, and conservation of momentum.

Force and Inertia

Review force, push, pull, balanced forces, unbalanced forces, change in state of motion, inertia of rest, inertia of motion, inertia of direction, and mass as a measure of inertia.

Newton's Laws of Motion

Practice Newton's first law, second law and third law. Revise the formulas p=mv and F=ma, SI unit of force, and relation between force, mass and acceleration.

Momentum and Applications

Revise momentum, unit of momentum, action and reaction, recoil of gun, walking, jumping, catching a ball, seat belts, conservation of momentum, and practical examples of laws of motion.

Key Force and Laws of Motion Concepts to Remember

Before repeating the test, make sure you can connect each law with its correct example. Most questions become easier when you first decide whether the situation is about inertia, acceleration, action-reaction, or conservation of momentum.

Common Mistakes in Force and Laws of Motion Questions

Force and Laws of Motion questions often depend on exact definitions and correct use of formulas. When checking your result, see whether one of these common mistakes affected your answer:

  • Confusing balanced forces with unbalanced forces
  • Thinking balanced forces always stop an object immediately
  • Forgetting that unbalanced force can change speed or direction
  • Confusing inertia with force
  • Forgetting that greater mass means greater inertia
  • Confusing Newton's first law with Newton's second law
  • Using p=ma instead of p=mv
  • Using F=mv instead of F=ma
  • Forgetting the unit of force is newton
  • Forgetting the unit of momentum is kg m/s
  • Thinking action and reaction act on the same object
  • Forgetting that action and reaction are equal and opposite
  • Confusing recoil with forward motion of the bullet
  • Forgetting that momentum is conserved when no external force acts
  • Ignoring direction in momentum and force examples

Force and Laws of Motion Practice FAQ

Common questions about this PSEB Class 9 Science Force and Laws of Motion practice test.

Yes. The Force and Laws of Motion practice test is free to use and does not require registration, payment, or a subscription.

The test contains 20 multiple-choice questions with four answer options, instant result checking, and detailed explanations.

Review force, balanced forces, unbalanced forces, inertia, Newton's three laws of motion, momentum, p=mv, F=ma, recoil and conservation of momentum.

Inertia is the tendency of an object to resist a change in its state of rest or uniform motion in a straight line.

Momentum is the product of mass and velocity. It is given by p=mv.

Newton's second law states that the rate of change of momentum is directly proportional to the applied force and takes place in the direction of the force. It is often written as F=ma.

Newton's third law states that for every action, there is an equal and opposite reaction. The two forces act on different objects.
