Question

Write the expression for the acceleration due to gravity?

Answer 1

1. The force of attraction by which a body is attracted toward earth is called the force of gravity.
2. Weight is equal to the product of mass and acceleration due to gravity.
3. $$\begin{gathered} g=\frac{GM}{R^2} \\ g\to acceleraationduetogravity \\ G\to gravitationalcons\tan t \\ M\to Massofplanet \\ R\to radiusofplanet \end{gathered}$$
4. Force of gravity depends on the distance from the earth.
5. The force of gravity is zero at the center of the earth.
6. The force of gravity decreases towards the center of the earth and also above the surface of the earth.
