Question

Explain the effect of Earth’s gravity on objects on the surface of Earth.

Answer 1

This is the sample answer: 
Gravity pulls objects toward Earth at a rate of 9.8 m/s2. Weight is the result of gravity's pull on a mass on Earth's surface.

Answer 2

Explanation: Gravitational force of earth is the attractive force which acts between any two bodies having mass. It is the product of the mass of the object and the acceleration due to gravity.

Mathematically,

$w=mg$

Where,

m = Mass of the object

g = Acceleration due to gravity which is $9.8ms^{-2}$

This is known as the weight of the object on Earth's surface.

This force is mainly responsible for:

1. Our walking on the Earth's surface.

2. Falling of an apple from the tree on the surface of Earth.
