The earth and the moon are attracted to each other by gravitational force. Does the earth attract the moon with a force that is greater or smaller or the same as the force with which the moon attracts the earth? Why?

Why will a sheet of paper fall slower than one that is crumpled into a ball?

Gravitational force on the surface of the moon is only $\frac{1}{6}$ as strong as the gravitational force on the earth. What is the weight in newtons of a $10\, kg$ object on the moon and on the earth?

What do you mean by free fall?

$A$ ball thrown up vertically returns to the thrower after $6\, s$. Find
$(a)$ the velocity with which it was thrown up,
