Newton’s law of Gravitation
there is a force of attraction between any two massive particles in the universe, which is known as gravitational force or force of gravity. Magnitude of this force is proportional to the product of masses of the particles and inversely proportional to the square of distance between them.”
Let two particals m1 and m2 ,and distance between ‘r’ than gravitational force ‘F of magnitude,
F=Gm1m2/r^2
Where,
G= universal gravitational constant
Universal gravitational constant——–
F=Gm1m2/r^2
m1=m2=1 kg
r=1 meter
Then,. G=F
SI unit of ‘G’.
Newton Metre^2/kg^2
Value of ‘G’. 6.67×10^-11
- Cloud Black Hole Energy Save Humanity’s FutureIN BRIEF When the sun dies in a few billion years, humanity must find another power source to survive. One candidate may be black holes, which are full of energy. A thought experiment suggests using the science-fiction concept of a space elevator to “mine” the thermal radiation from a black hole. A space elevator would use a box attached to a rope dangling down… Read more: Cloud Black Hole Energy Save Humanity’s Future
- Kepler’s law of planetary motion.On the basis of Tycho Brahe khagoli abundant, Kepler gave the following three rules regarding the orbiting motion of the Sun in the solar family. The orbits of the planets are different. The law of regional speed. (1)Lows of Orbits the planet and the Sun in the turtle group of a planet sets the same area in the same antralon, that is, the regional speed of… Read more: Kepler’s law of planetary motion.

- What is a Centripetal Force?? And formula of Centripetal Force.Definition—- “A force acting on a body causing it to move in a circular path is known as centripetal force. The direction of this force is always directed towards the centre of the circle.” “a centripetal force accelerates a body by changing the direction of the bodies velocity without change in the body’s speed.”… Read more: What is a Centripetal Force??

- What is a Momentum???English Definition– “The net force on a body is equal to the product of the body’s mass and the acceleration of the body.” P=m v The unit of momentum। Kg_m/sec or newton_sec।। It is also call the Law of conservatioce of force. “The of change of the linear momentum is directly propotional to the impressed force, and takes the dierection in which the force… Read more: What is a Momentum???
