Question

Q#2 Explain the law of Gravitation. What will be the effect of elevation on the force of attraction between two bodies. What happens when the bodies are on the moon​

Answer 1

Answer:

Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers

Answer 2

GRAVITATIONAL LAW:

• Newton's Law of Gravitation states that the gravitational force between two masses is directly proportional to the product of the masses and inversely proportional to the square of the distance of separation.

$\boxed{F \propto \dfrac{m_{1} \times m_{2}}{ {r}^{2} } }$

Now, introducing a constant (UNIVERSAL GRAVITATION CONSTANT):

$\boxed{F =G \times \dfrac{(m_{1} \times m_{2})}{ {r}^{2} } }$

________________________

• If elevation means separation between the bodies increases, then value of 'r' increases and the value of force (F) decreases.

• If two bodies are taken on moon, we need to calculate the net Gravitational force on one body as a complex vector addition of force due to the 2nd body and due to Moon.
