What force is acting on a flying ball?

User Avatar
The forces acting on a flying ball are: 1. The frictional force exerted by air on the motion of the ball. 2. The gravitational force of the earth, of course.

How are the physical properties of an orange different from those of a basketball?

User Avatar
-- Basketballs are much larger in size than oranges. -- Basketballs are filled with air, but oranges are filled with juice and pulp. -- Basketballs have much higher air pressure than oranges. -- Oranges grow on trees while basketballs are manufactured. -- The density of an orange is much greater than the density of a basketball. -- An orange is juicy, easy to chew, and sweet, whereas a basketball is dry, rubbery, and tastes terrible. -- A basketball can bounce and a orange cannot bounce.

What is the difference between bulk specific gravity and apparent specific gravity?

User Avatar
Dry Bulk Specific Gravity does not take into account for anything getting into the permeable or impermeable voids of say a stone by water for instance. Saturated Surface Dry Bulk Specific Gravity takes into account for anything getting into the permeable voids only of say a stone by water. Apparent Specific gravity takes into account for the volume of the impermeable voids and not anything getting into the permeable voids of say a stone by water.
