Does gravity have any effect on inertial mass?

$A$ stone is dropped from the edge of a roof.
$(a)$ How long does it take to fall $4.9 \, m$?
$(b)$ How fast does it move at the end of that fall?
$(c)$ How fast does it move at the end of $7.9 \, m$?
$(d)$ What is its acceleration after $1 \, s$ and after $2 \, s$?

What is the shape of the path followed by a projectile?

The equation $F = G \frac{m_1 m_2}{r^2}$ is valid only for:

The force of gravitation between two bodies varies with the distance $r$ as:

State whether the following statement is true or false:
The force of attraction between two bodies is called gravity.
