What is the name given to the path followed by a projectile?

$A$ man at the top of a tower throws an object horizontally,whereas he simply drops another. Will these two objects reach the earth at the same time?

The factors associated with the motion of an object are: Force,Velocity,Acceleration,and Momentum. Out of these four factors,which one remains constant for all bodies—large or small—undergoing a free fall?

The weight of any person on the moon is about $1/6$ times that on the earth. He can lift a mass of $15\, kg$ on the earth. What will be the maximum mass,which can be lifted by the same force applied by the person on the moon (in $, kg$)?

The value of $g$ on the earth's surface is $9.8 \, m s^{-2}$. Suppose the earth suddenly shrinks to one-third of its present size without losing any mass. What is the value of $g$ on the surface of the shrunk earth (in $, m s^{-2}$)?

$A$ stone is dropped from the roof of a building. It takes $4 \, s$ to reach the ground. Find the height of the building. $(g = 9.8 \, m \, s^{-2})$
