State and proof of work energy theorem |
| Answer» Work energy theorem states that the change in kinetic energy of an object is equal to the net work done on it by the net force.Let us suppose that a body is initially at rest and a force F is applied on the body to displace it through dS along the direction of the force. Then, small amount of work done is given bydW = FdSAlso, according to Newton\'s second law of motion, we haveF mawhere a is acceleration produced (in the direction of force) on applying the force. Therefore,dW = MadS = M dv/st dSOr dW = M Ds/dt dv = MvdvNow, work done by the force in order to increase its velocity from u (initial velocity) to v (final velocity) is given byW = 1/2 mV2 - 1/2 Mu2Hence, work done on a body by a force is equal to the change in its kinetic energy. | |

Definition of inertial frame of reference and non inertial frame of reference |
| Answer» =)=) Inertial frame of reference =)=)A reference frame in which an object remains either at rest or at a constant velocity unless another force acts upon it. Basically they follow Newton\'s First law of motion.Ex: A person inside a stationary car. ## Non-inertial frame of reference ##A non-inertial frame is an frame where some external force works upon it.Ex: An accelerating car pushes us back into the seat. | |

Coulombs law |
|
Answer» In 1785 the French physicist Charles Augustin Coulomb measured the electric force between small charged spheres using a torsion balance. He then formulated his observations in the form of Coulomb\'s Law. Coulomb\'s Law is an electrical analog of Newton\'s Universal Law of Gravitation. It states thatThe force of attraction or repulsion between two stationary point charges is(i) directly proportional to the product of the magnitude of two charges.(ii) inversely proportional to the square of the distance between them.This force acts along the line joining the two charges.

Name ot the strongest force in the nature? |
|
Answer» Nuclear force as explained above Nuclear force is the strongest force in the nature .The particles inside the nucleus are charged particles (protons) and neutral particles (neutrons) which are bounded to each other by a strong interaction called nuclear force or strong force. Hence, they may be defined as the forces binding the nucleons (protons and neutrons) together in a nucleus. These are responsible for the stability of the atomic nucleus. |

What is the difference between radius of gyration and moment of inertia? |
| Answer» Radius of gyration, on the other hand, has a relationship with moment of inertia however it is defined as the square root of moment of inertia divided by the system\'s mass. This number gives you a distance from the axis of rotation at which there is an equal moment of inertia than that of the entire system. | |

If s=3t^2+4t+9 find velocity at t=2sec. Also find average velocity between 1sec and 4sec |
| Answer» Velocity at t=2sec is 16m/s. You just need to differentiate the distance equation with respect to time which will give you--> v=6t+4 and now just substitute the value of time that is 2 sec and this will give 16m/s. | |
