PSEB Class 11 Laws of Motion Practice

Laws of Motion is a key Class 11 Physics chapter that explains how force affects the motion of a body. It connects basic ideas such as inertia, momentum, impulse, friction, equilibrium, and centripetal force with Newton's three laws of motion.

Questions from this chapter may ask students to identify Newton's laws, calculate force or momentum, understand impulse, apply conservation of linear momentum, analyse friction, or recognise the direction of centripetal force in circular motion.

Use this 20-question practice test before broader Class 11 Physics revision. After completing the test, review every explanation carefully and repeat the test after revising weak areas such as Newton's laws, friction, momentum, impulse, and circular motion.

What to Review for Laws of Motion

Focus on Newton's laws, momentum, impulse, equilibrium, friction, and centripetal force.

Newton's Laws and Inertia

Review the intuitive concept of force, inertia, Newton's first law, Newton's second law, Newton's third law, mass, acceleration, and net force.

Momentum and Impulse

Practice momentum, impulse, change in momentum, conservation of linear momentum, and applications of Newton's laws in simple situations.

Friction and Circular Motion

Revise static friction, kinetic friction, rolling friction, lubrication, centripetal force, and the role of friction in circular motion.

Key Laws of Motion Concepts to Remember

Before repeating the test, make sure you can connect each law with its physical meaning. Many Laws of Motion questions become easier when you identify whether the situation involves inertia, net force, momentum, impulse, friction, or circular motion.

Common Mistakes in Laws of Motion Questions

Laws of Motion questions often look simple, but small mistakes in direction, force balance, or friction can change the answer. When checking your result, see whether one of these common mistakes affected your answer:

  • Confusing mass with weight
  • Thinking force is always needed to maintain uniform motion
  • Forgetting that inertia depends on mass
  • Using Newton's second law without considering net force
  • Confusing momentum with force
  • Confusing impulse with momentum
  • Forgetting that impulse equals change in momentum
  • Assuming action and reaction act on the same body
  • Forgetting that action and reaction are equal and opposite
  • Using conservation of momentum when external force is present
  • Confusing normal reaction with weight
  • Assuming friction always acts opposite to motion, not relative motion
  • Confusing static friction and kinetic friction
  • Forgetting that limiting friction is proportional to normal reaction
  • Using wrong coefficient of friction formula
  • Assuming rolling friction is greater than sliding friction
  • Forgetting that lubrication reduces friction
  • Taking centripetal force as a new separate force
  • Using tangential direction for centripetal force
  • Forgetting that centripetal force is directed toward the centre

Laws of Motion Practice FAQ

Common questions about this PSEB Class 11 Physics Laws of Motion practice test.

Yes. The 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, inertia, Newton's laws of motion, momentum, impulse, conservation of linear momentum, equilibrium of forces, friction, lubrication, and centripetal force.

Newton's first law explains inertia. A body remains at rest or in uniform straight-line motion unless acted upon by an external unbalanced force.

Newton's second law relates net force to mass and acceleration. In simple form, it is written as F = ma.

Impulse is the product of force and time interval. It is also equal to the change in momentum of a body.

If no external force acts on a system, the total linear momentum of the system remains constant.

Centripetal force is the net force directed toward the centre of a circular path. It is responsible for circular motion.

Yes. Review the explanations, revise difficult concepts, and complete the 20-question test again whenever you need additional practice.
