Question three. What Is Intertia?
Answer :
The belongings of a fabric frame by distinctive feature of which the frame at relaxation has a tendency to stay at rest and an object in motion tends to stay in movement is called interia.
Bodies have two kinds of intertia :
Interia at rest
Intertia of motion
Question four. How Is Interia Related With Mass Of The Body?
Answer :
A quantitative degree of the belongings of interia of an item is its mass. Greater the mass of the frame, larger is the effort needed to set it in motion. Also greater the mass of a frame, the bigger is the effort needed to prevent it if it's miles in movement already.

Physics Interview Questions
Question 8. What Is Gravitational Force?
Answer :
There is a gravitational pressure of attraction between any two gadgets. All items fall closer to the earth due to gravitational pressure of earth, F= mg, where m is mass of the body. The route of this force is towards the centre of the earth. This force is powerful over huge distances.
Question 9. What Is The Electrostartic Force?
Answer :
There are forms of fees; fantastic and terrible. The electrostatic pressure among two opposite costs is appealing while between comparable fees it is repulsive. This pressure is powerful over massive distances.
Dimensions Interview Questions
Question 10. What Is Magnetic Force ?
Answer :
The pressure between magnets is known as magnetic pressure. The electric and magnetic forces are two facts of the overall electromagnetic pressure information.
Question eleven. What Is Atomic And Nuclear Forces?
Answer :
With the help of these forces we will provide an explanation for he observations made on atoms and nucleons. These observations can be explained on varieties of forces called strong and vulnerable forces. Strong force acts among protons and neutrons in a nucleus. It acts simplest over a completely brief range of approximately 10 -15 m. A susceptible force acts among any standard debris like electron and neutron.
Unit of Measurement Interview Questions
Question 12. A Horse Cannot Pull A Cart And Run In Empty Space.Why ?
Answer :
Because there's no friction in empty area.
Sound Interview Questions
Question thirteen. Passengers Are Thrown Forward From Their Seats When Speeding Bus Stops Suddenly?
Answer :
This is because if inertia of movement.
Question 14. State The Law Of Conservation Of Momentuem?
Answer :
When two or more bodies have interaction with each other, their general momentum stays consistent, provided no outside forces are appearing.
Question 15. What Is Force Of Friction?
Answer :
When a stable body is moved over the surface of every other stable body, an opposing force acts in between the two surface ( parallel to them ) and it has a tendency to spoil the relative motion in among them. This opposing pressure is called pressure of friction. The importance of the pressure of friction depends upon the nature of the two surfaces in touch.
Gravitational Interview Questions
Question 16. Why Are The Types Of Vehicles Retreaded If They Become Smooth?
Answer :
Rolling of a wheel on floor is viable because of the friction among the 2. Due to this cause the kinds have treads which increase friction and avoid slipping.
Question 17. What Is Meant By Rolling Friction ?
Answer :
The frictional force among two surfaces while one roles over the other is referred to as rolling friction. A wheel or a ball is slightly flattened while its rests over a floor. A surface also is barely dented. Because of this deformation a resistance pressure arises when the wheel or ball rolls on a surface. This is known as rolling friction. Rolling friction is lots smaller than sliding friction.
