Example of law of action and reaction |
| Answer» Newton’s third law of motion states thatIn any interaction between two bodies , force applied by the first body on the second is equal and opposite to the force applied by the second body on the first.Examples:\tWhen a man jumps from a boat to the shore, the boat moves away from him. The force he exerts on the boat (action) is responsible for its motion and his motion to the shore is due to the force of reaction exerted by the boat on him.\tIf you hit the wall with your fist, the wall also hits your fist with the same force , which you feel. | |

Progectyil motion |
|
Answer» Projectile,, not progectyil A projectile is an object upon which the only force is gravity. Gravity acts to influence the vertical motion of the projectile, thus causing a vertical acceleration. The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity. |

What is constraint equation? |
| Answer» In mechanics, a constraint algorithm is a method for satisfying constraints for bodies that obey Newton\'s equations of motion. There are three basic approaches to satisfying such constraints: choosing novel unconstrained coordinates ("internal coordinates"), introducing explicit constraint forces, and minimizing constraint forces implicitly by the technique of projection methods.Constraint algorithms are often applied to molecular dynamics simulations. Although such simulations are sometimes carried out in internal coordinates that automatically satisfy the bond-length and bond-angle constraints, they may also be carried out with explicit or implicit constraint forces for the bond lengths and bond angles. Explicit constraint forces typically shorten the time-step significantly, making the simulation less efficient computationally; in other words, more computer power is required to compute a trajectory of a given length. Therefore, internal coordinates and implicit-force constraint solvers are generally preferred. | |

Can speed of a body be negative |
|
Answer» No speed of a body is always positive it never be negative further , velocity can be zerobut speed is never zero for a non-zero distance covered but velocity can nope NoAs speed is a scalar quantity , ie, measures magnitude only. As magnitude cannot be negative thus speed remains positive Or else 0.? |

Derivarion of elastic collion of one dimension |
| Answer» We start with the elastic collision of two objects moving along the same line—a one-dimensional problem. An elastic collision is one that also conserves internal kinetic energy. Internal kinetic energy is the sum of the kinetic energies of the objects in the system. | |

What do you mean by parallel vector |
| Answer» If the lines of action of the two vectors are same or parallel to each other, then the vectors are parallel. The magnitude of two vectors need not to be equal for parallel vectors.The parallel vectors are of two types:(a) Like parallel vector: Two vectors are said to be like parallel vectors if they have same direction.(b) Unlike parallel vectors: Two vectors in the opposite direction are called unlike parallel vectors. | |

What is the advantage of friction |
|
Answer» Without friction we are not able to write,walk,and byclining etc. Friction plays a vital role in our daily life. Without friction we are handicap.1. It is becomes difficult to walk on a slippery road due to low friction. (move on ice too)2. We can not fix nail in the wood or wall if there is no friction which holds the nail.3. A horse can not pull a cart unless friction furnishes him a secure . |

Explain why constant pressure is greater than constant volume |
| Answer» The heat capacity at constant pressure is greater than the heat capacity at constant volume because when heat is added at constant pressure, the substance expands and work. QV = CV ∆T = ∆U + W = ∆ U as there no work is done. | |

what is apparent weight during take off an astronaut whose actual weight is 750N |
| Answer» Firstly, the mass of the astronaut is const. and before the take off his weight was , F = m × a . Then , as the rocket accelerates the acceleration of the astronaut becomes 5g + 1g = 6g . Hence, we can now simply find his apparent weight from that formula • F = m × a like that , F = 750N × 6g = 4500g | |
