Normal practice, or a Simulated test

Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 35-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

The computer-based test format: one clock, a question palette, and a score the moment you submit.

  • A clock that does not pause. 35 minutes from the moment you begin, and the paper is submitted for you when it reaches zero.
  • Question palette. Answered, not answered and marked for review, section by section, as the real interface has it.
  • Full screen, proctored. The test takes over the screen; leaving it three times submits the paper.
  • Answers hidden until you submit. The key, the explanations and your score all arrive together at the end.

About this test

Laws of Motion GK Practice Quiz Level 3: Newton's Laws and Momentum

Newton's laws, momentum and the equations of uniform acceleration form the core of this Level 3 Motion and Laws of Motion GK quiz on Aptitude360. It is a General Awareness physics set that pairs concept checks with short numericals on force, momentum, velocity and distance. Every question includes a written explanation.

Concepts tested in this Motion and Laws of Motion set

  • Describing motion: distance versus displacement, speed versus velocity, and scalar versus vector quantities
  • Newton's laws: inertia in a bus that starts or stops suddenly, force as mass times acceleration, and why action and reaction do not cancel
  • Momentum: calculating momentum, conservation in collisions, and the recoil of a gun
  • Impulse in daily life: why a fielder pulls the hands back while catching a fast ball
  • Equations of motion: the meaning of each symbol, which relation has no time term, and numericals from rest
  • Circular motion and units: why uniform circular motion is accelerated, and matching newton, joule and momentum units

Key formulas for laws of motion

  • First equation: \( v=u+at \)
  • Second equation: \( s=ut+\dfrac{1}{2}at^{2} \)
  • Third equation: \( v^{2}=u^{2}+2as \)
  • Momentum: \( p=mv \)
  • Second law: \( F=ma \)
  • Conservation of momentum: \( m_{1}u_{1}+m_{2}u_{2}=m_{1}v_{1}+m_{2}v_{2} \)

Revision tips for motion and force questions

  • List the known and unknown quantities first, then pick the equation of motion that contains exactly those symbols
  • Remember that a body starting from rest has zero initial velocity and a body coming to rest has zero final velocity
  • For recoil questions, treat the initial total momentum as zero, so the gun and bullet move in opposite directions
  • Check whether a quantity needs a direction before deciding if it is scalar or vector

Who should take this Level 3 physics quiz

It is meant for General Awareness aspirants who have revised the basics of motion and want to test themselves at the advanced stage with mixed concept and numerical questions.

FAQs about Motion and Laws of Motion – GK Quiz with Answers – Level 3

What are Newton's three laws of motion?
The first law says a body stays at rest or in uniform motion unless an unbalanced force acts on it. The second law says force equals mass times acceleration. The third law says every action has an equal and opposite reaction.
What is the difference between distance and displacement?
Distance is the total length of the path travelled and is a scalar. Displacement is the shortest straight-line length from the initial to the final position, with direction, so it is a vector and can be zero even when distance is not.
Why does a gun recoil when a bullet is fired?
Before firing, the total momentum of the gun and bullet is zero. To conserve momentum, the gun gains momentum equal in size and opposite in direction to the bullet, so it moves backward.
Why is uniform circular motion called accelerated motion?
In uniform circular motion the speed stays constant but the direction of motion changes at every point. Since velocity includes direction, the velocity keeps changing, which means the body is accelerating.
