Questions on the motion topic in physics are a common type of question that students are asked to answer in competitive exams. These questions can be challenging, but they can also be very rewarding to solve. To solve motion questions, it is important to understand the different types of motion, as well as the equations of motion. Once you have a good understanding of these concepts, you can start to tackle motion questions.

With a little practice, you will be able to solve motion questions with ease. So, we have attached 10 questions of Motion for you to practice with. You should aim to answer these questions in less than half a minute for each.

Comment below your score, considering each question has 1 mark only. If you scored 8 to 10, congratulations! You are one step closer to selection. If you have scored 5 to 8 marks, then you are doing well, keep it up. If you have scored less than 5 marks then you need to work a little harder on this subject. But don&#39;t worry, we are here to help you master the subject.

Let&#39;s check the answers and solutions and try to find out what went wrong. 
 

<h2>Answers and Solutions</h2>

Q:1 The correct answer is Option 1 i.e. Newton&#39;s Second Law of Motion

Riding a bicycle is a good example of Newton&#39;s Second Law of Motion.

Newton&#39;s first law states that every object will remain at rest or in uniform motion until and unless an external force is applied to it.

Newton&#39;s second law states that the rate of change of momentum of a body is directly proportional to the force applied to it.

Newton&#39;s third law states that for every action there is an equal and opposite reaction.

 

Q:2 The correct answer is Option 1 i.e. Projectile motion

Projectile Motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity.

In Linear Motion, the particles move from one point to another in either a straight line or a curved path.

Rotary Motion is the motion that occurs when a body rotates on its own axis.

Oscillatory Motion is the motion of a body about its mean position.

 

Q:3 The correct answer is Option 1 i.e. Newton’s First Law of Motion

First Law of Motion: It states that an object at rest remains at rest and an object in motion remains in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Second Law of Motion: It states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.

F = ma

Force = mass x acceleration

Third Law of Motion: It states that for every action, there is an equal and opposite reaction.

Pascal’s Law: It states that pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.

 

Q:4 The correct answer is option 1 i.e. Longitudinal waves

The orientation of particle motion relative to the direction of energy propagation is one 0f the ways waves are characterized. There are three categories:

Longitudinal waves - Movement of the particles is parallel to the motion of the energy.  Sound waves moving through the air is an example of this type of wave.

Transverse waves - Movement of the particles is at right angles (perpendicular) to the motion of the energy. Movement of a wave through a solid object like a stretched rope or a trampoline is an example of this type of wave.

Surface waves - particles travel in a circular motion.  These waves occur at interfaces.  Examples include waves in the ocean and ripples in a cup of water.

 

Q:5 The correct answer is option 1 i.e. Radian.

Rotational motion refers to anything spinning or moving in a circular path, in a fixed orbit. It is also called angular motion or circular motion.

To describe the angular displacement of an object in rotational motion the natural unit radians (π) is used since rotational motion involves studying circular paths.

One revolution (360 degrees) equals 2π radians​.

 

Q:6 The correct answer is option 4  i.e. Centripetal Force.

The component of force acting on an object to keep it moving in curvilinear motion along a circular path, directed toward the axis of rotation is called Centripetal Force.

Centripetal Force defined by Isaac Newton in 1684.

Centripetal Force is a real force that keeps the object from flying out.

Formula of Centripetal Force (F) = mac = mv2/r.

 

Q:7 The correct answer is Option 2 i.e. Second Law

Kepler’s second law is also known as the &#39;The law of equal areas&#39;.

According to this law, a planet no matter where it is in its orbit, covers the same area of space in the same amount of time.

 

Q:8 The correct answer is Option 4 i.e. Simple harmonic motion

Motion of a piston in an automobile engine is an example of Simple harmonic motion.

Simple harmonic motion are oscillatory(motion that moves back and forth) and periodic (motion that repeats itself after an interval of time) types of motion.

In Simple harmonic motion, the restoring force of a moving object is directly proportional to the displacement of the object from its equilibrium position.

 

Q:9 The correct answer is Option 3 i.e viscosity of the fluid

Brownian motion refers to random movements displayed by microscopic particles suspended in fluids (liquids or gases) resulting from the impact of molecules of the surrounding medium.

The speed of the Brownian motion is inversely proportional to the viscosity of the fluid. The lower the viscosity of the fluid, the faster the Brownian movement.

 

Q:10 The correct answer is Option 4 i.e Stroboscope

A stroboscope is an instrument that uses an intense, high-speed light source for visual analysis of objects in periodic motion and for high-speed photography.

This device is used for viewing rapidly moving objects by creating an optical illusion that appears to slow down or stop motion.
