Gravity is defined as: Select one: a. an apple falling from a tree toward the ground. b. ability to accomplish a job with the least difficulty. c. natural force or pull toward the earth. Correct d. none of the above.

c. natural force or pull toward the earth

Explanation:

Gravity of the earth is the force of attraction that it naturally possesses to attract any mass.

An apple falls on the earth due to this force of gravity.

The force of gravity near to the surface of the earth is given as:

where:

m= mass of the body

g= acceleration due to gravity

The variation of the gravitational force with height is given as:

where:

where

R = radius of the earth

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.
