Interview Questions.

Q1. If Two Objects Have Equal Momenta, Then?

The lighter items is transferring faster than heavier.

Q2. A Bomb Is Dropped From An Aircraft When It Is Directly Above A Target At A Height Of a thousand Metre. The Aircraft Is Moving With A Velocity Of 500 Km / Hour. Will The Bomb Hit The Target ?

The bomb will not hit the target. The bomb wil strike at a point 1982 metre faraway from the target. 

Q3. What Is Force?

It is an effort which sets the objects in motion.

Q4. Which Is The Force That Makes The Car Go Straight?

Centrifugal pressure

Q5. A Stone Tied At The End Of A Rope Is Being Whirled In A Horizontal Circle. Suppose The String Breaks Then?

The stone moves toward the centre of the circular course.

Q6. What Is The Energy Of A Body Is Defined As ?

It is defined as its potential to do work.

Q7. What Is Meant By Rolling Friction ?

The frictional force among  surfaces while one roles over the other is called rolling friction. A wheel or a ball is barely flattened when its rests over a surface. A floor is also slightly dented. Because of this deformation a resistance pressure arises while the wheel or ball rolls on a floor. This is called rolling friction. Rolling friction is much smaller than sliding friction.

Q8. What Is A Force Field?

It is region in which at each point, the magnitutde and the path of the pressure is known.

For example: the gravitational force due to the earth appearing on a mass of 1kg can be certain at all the factors at the floor of earth each in importance and direction. We then say that there is a gravitational “ force field ”

Q9. What Is Displacement ?

Displacement is the vector that specifies the alternate in function of a factor or a particle in connection with a preceding position. When the preceding point is the foundation, that is higher referred to as a role.

Q10. What Does The First Law Of Thermodynamics Confirm ?

It confirms the law of conversion of strength.

Q11. What Is Atomic And Nuclear Forces?

With the help of those forces we will provide an explanation for he observations made on atoms and nucleons. These observations can be defined on  types of forces known as robust and susceptible forces. Strong force acts between protons and neutrons in a nucleus. It acts simplest over a very brief range of about 10 -15 m. A weak pressure acts between any  fundamental debris like electron and neutron.

Q12. What Is Force Of Friction?

When a stable body is moved over the surface of every other strong body, an opposing force acts in between the 2 surface ( parallel to them ) and it has a tendency to smash the relative movement in among them. This opposing pressure is known as pressure of friction. The importance of the force of friction depends upon the character of the 2 surfaces in contact.

Q13. What Is A Force?

It is defined because the outside organization that adjustments or has a tendency to alternate the kingdom of relaxation or uniform motion of a frame in a straight line.

Q14. A Horse Cannot Pull A Cart And Run In Empty Space.Why ?

Because there's no friction in empty area.

Q15. The Heat Added To A System Is Equal To?

A exchange in its inner kinetic strength, ability strength.

Q16. Why Are The Types Of Vehicles Retreaded If They Become Smooth?

Rolling of a wheel on surface is viable because of the friction among the two. Due to this cause the sorts have treads which growth friction and keep away from slipping.

Q17. A Rocket Works On The Principle Of Conservation Of Momentum. It Follows From Which Law ?

Newton’s 1/3 regulation.

Q18. Who Helped To Found The New Science Of Thermodynamics, Establishing Clear Relationship Between Heat, Work And Energy?

Lord Kelvin

Q19. When A Force Acts On A Body In Its Direction Of Motion Then The Momentum?

Keeps on increasing.

Q20. The First Law Of Thermodynamics Is Concerned With The Conservation Of ?

Energy 

Q21. What Is Intertia?

The assets of a fabric body by distinctive feature of which the body at relaxation has a tendency to stay at relaxation and an object in motion has a tendency to stay in movement is known as interia.

Bodies have two varieties of intertia :

 Interia at relaxation

 Intertia of movement 

Q22. Which Are The Basic Types Of Forces?

 Gravitational force

 Electrostatic pressure

 Magnetic force

 Atomic force

 Nuclear pressure

Q23. How Is Interia Related With Mass Of The Body?

A quantitative measure of the assets of interia of an object is its mass. Greater the mass of the body, larger is the attempt had to set it in motion. Also more the mass of a body, the larger is the attempt needed to prevent it if it's far in motion already.

Q24. What Is The Electrostartic Force?

There are two forms of prices; nice and bad. The electrostatic pressure between two opposite costs is appealing while between two comparable prices it is repulsive. This pressure is effective over massive distances.

Q25. The Motion Of A Billiard Ball Or Carom Coin Represents The Motion Of?

Two dimensions.

Q26. What Are Allotropes ?

They are different bodily systems of a solid substance,

Example: diamond and graphite both are, allotropes of carbon.

Q27. An Astronau Just Releases A Spoon Out Of His Spaceship Acclerating In The Interstellar Space At A Constant Rate Of a hundred M / S 2. Then The Acceleration Of The Spoon At The Instant When It Is

Zero.

Q28. If The Particles Move With Same Velocity And Their Paths Are Parallel, Their Motion Is Called?

Trlatory and rotatory movement.

Q29. State The Law Of Conservation Of Momentuem?

When two or greater bodies interact with one another, their general momentum stays regular, supplied no external forces are acting.

Q30. Which Are The Main Forms Of Energy In Physics ?

Heat, Light, Sound, Magnetic, Electric, Kinetic, Potential etc,, are the main styles of strength.

Q31. What Is Gravitational Force?

There is a gravitational force of appeal between any two gadgets. All gadgets fall towards the earth because of gravitational pressure of earth, F= mg, where m is mass of the body. The route of this pressure is toward the centre of the earth. This pressure is effective over massive distances.

Q32. What Is The Principle Of The Working Of A Rocket ?

Conservation of momentum

Q33. Which Is Called A Rotatory Motion ?

When a frame rotates about a set axis the movement is stated to be rotatory.

Q34. When An Object Is In Equilibrium Or Balanced The Turning Force On One Side Of The Fulcrum Is Equal To The?

Turning force on the opposite side.

Q35. Who Was The First Person To Formulate The Laws Concerning Rest And Motion ?

Isaac Newton.

Q36. Which Force Causes Weightlessness In Orbit ?

Centripetal force

Q37. What Is Meant By Dynamics?

The have a look at of motion, which describes a relation among pressure and its impact, is referred to as dynamics.

Q38. Who Used Turning Forces To Weigh Things In Ancient Time ?

Rom

Q39. Passengers Are Thrown Forward From Their Seats When Speeding Bus Stops Suddenly?

This is because if inertia of motion.

Q40. What Is Called The Crystallography ?

It is the technique used to have a look at the shape of crystals.

Q41. What Is Magnetic Force ?

The pressure between two magnets is called magnetic pressure. The electric powered and magnetic forces are two information of the general electromagnetic pressure records.
