What is moment of inertia |
|
Answer» The virtue of property by which if any object will be rotate about an fixed point is known as moment of inertia. It is denoted or represented by(I)or in other wordsThe product of the mass of the object and squre of the seperated distance is known as moment of inertia. The moment of inertia of an object is a calculated quantity for a rigid body that is undergoing rotational motion around a fixed axis. It is calculated based upon the distribution of mass within the object and the position of the axis, so the same object can have very different moment of inertia values depending upon the location and orientation of the axis of rotation.Conceptually, moment of inertia can be thought of as representing the object\'s resistance to change in angular velocity, in a similar way to how mass represents a resistance to the change in velocity in non-rotational motion, under Newton\'s laws of motion. |

Express centripetal acceleration. |
|
Answer» Deriving the\xa0centripetal acceleration\xa0formula. A body that moves in a circular motion (of radius r) at constant speed (v) is always being\xa0accelerated. The acceleration\xa0is at right angles to the direction of motion (towards the center of the circle) and of magnitude v2\xa0/ r. It is the rate of change of tangential velocity. |

Sir I want to know about 2nd law of motion |
|
Answer» The acceleration of an object is produced by a net force is directly proportional to the magnitude of the net force in the same direction as the net force and inversely proportional to the mass of thr object. The rate of change of momentum is directly proportional to the applied force on which the force is applied According to second law of motion "The rate of change of momentum with respect to time is directly proportional to applied force on it . . F=ma F=maForce=mass*acceleration |
