Pressure
Asked by | 01 Sep, 2012, 12:43: PM
answered-by-expert Expert Answer
the pressure on ourself is due to the weight of air above our head.
So clearly as we move up, the amount of air above our head decreases and so is the pressure.
 
u can also get it from the fact the pressure is defined as the force exerted per unit area.

CBSE 9 - Physics
A boy throws a steel ball straight up. Consider the motion of the ball only after it has left the boy's hand but before it touches the ground and assume that forces exerted by the air are negligible. For these conditions, the force(s) acting on the ball is (are): a. A downward force of gravity along with a steadily decreasing upward force b. A steadily decreasing upward force from the moment it leaves the boy's hand until it reaches its highest point on the way down there is a steadily increasing downward force of gravity as the object gets closer to the earth c. Constant downward force of gravity along with an upward force that steadily decreases until the ball reaches it highest point on the way down there is only a constant downward force of gravity d. Constant downward force of gravity only
