Prove that Newton\'s 2nd law of motion is the real law of motion? |
| Answer» Proof. When we can show that Newton’s first and third law are contained in the second law, then we can say that it is the real law of motion.(i)\tFirst law is contained in second law: According to Newton’s second law of motion,It means that there will be no acceleration in the body if no external force is applied. This represents that a body at rest will remain at rest and a body in uniform motion will continue to move along the same straight line in the absence of an external force. This corresponds to Newton’s first law of motion. So, first law of motion is contained in Second law of motion | |

If we kept a glass of hot milk into space...then what will be the effect on it? |
|
Answer» Sorry not due to absence of atmospheric pressure but due to absence of gravity Since there is absence of atmosphere in space thus heat loss by convection is not possible it will renain hot. Also there is absence of atmospheric pressure in space therefore the milk wont acquire the shape of glass |

Difference between gravitational potential energy and gravitational potential. |
| Answer» Gravitational potential energy is energy an object possesses because of its position in agravitational field. The most common use ofgravitational potential energy is for an object near the surface of the Earth where thegravitational acceleration can be assumed to be constant at about 9.8 m/s2.The gravitational potential (V) is thegravitational potential energy (U) per unit mass: where m is the mass of the object.Potential energy is equal (in magnitude, but negative) to the work done by thegravitational field moving a body to its given position in space from infinity. | |
