Difference between static friction kinetic friction and limiting friction |
| Answer» static friction :- if a body is at rest and we apply the insufficient force to slide it so that the body keeps in rest without tending to any disturbance in its position due to a opposite force acting on it between the two contact surfaces. that opposite force is known as static frictionlimiting friction:- it can be defined as the friction offered by contact surface about which body tends to move due to external increasing force. ie., it is the maximum value of static friction.kinetic friction:; the friction exerted during the motion of the body. | |

Why newton second law of motion is real law of motion |
|
Answer» Newton\'s second law is the real law of motion in the sense that the firest and third law of motion can be derived from the 2nd law of motion. This means that if no force is applied on the body, its acceleration will be zero Newton\'s second law of motion can be formally stated as follows: The acceleration of an object as 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 the object. |

Why does a railway track have a particular shape like I |
| Answer» This is typical shape of the cross-section of a track laid with Flat-footed Rails. ... These are shaped so for following purposes: The top portion or the HEAD of the rail is thicker to take up the impact of the fast moving wheels, and carry the load of trains preventing abrasion of the tracks. | |

What is center of mass |
|
Answer» A hypothetical point where whole mass of a system is supposed to be concerned It is point it is a point where n terms of the system is supposed to be concentrated such that if entire external force is supposed to be acting at centre of mass then straight line of motion of system remain unchanged The point where whole mass of a body is concentrated .Actually there is no such point where whole mass of body is concentrated. It is used for study of macroscopic body. |
