Why does a man get hurt when he jumps from a significant height even though newtons universal gravitational law says that height is inversely proportional to acceleration due to gravity?

The difference in gravitational acceleration depends on the distance from the centre of the earth , not the surface. The equation for the new rate of accelration calculated from the surface rate is:
>
a = k / ( ( d / r )2 )
>
where:
a = acceleration due to gravity at new position
k = surface rate of acceleration ( use 9.82 (m/s)/s )
d = distance from earths centre to new position ( r + height of jump) ( 6376000 metres)
r = surface radius ( use 6371000 metres )

Even if you jump from 5,000 metres the rate of acceleration would be :
>
9.8046 (m/s)/s , which is 99.84 % of the rate at the surface

Is the amount of acceleration directly proportional to the fore and to the mass?
No, an object's acceleration is inversely proportional to an objects mass.
By how many times would the gravitational force between two objects decrease if the distance between the two objects was tripled?
By a factor of 9. Gravitational force is inversely proportional to the square of the distance.By a factor of 9. Gravitational force is inversely proportional to the square of the distance.By a factor of 9. Gravitational force is inversely proportional to the square of the distance.By a factor of 9. Gravitational force is inversely proportional to the square of the distance.
How force affects mass and acceleration?
force is directly proportional to acceleration and acceleration is inversely proportional to mass of the body
Does gravitational force depend inversely on mass?
No, it is proportional to mass.
Does mass and air resistance affect the gravitational attraction between objects?
Yes mass affects the gravitational acceleration between objects. But air resistance doesn't affect the gravitational acceleration, it only affects the net acceleration of the objects concerned. According to Newton's Law of Gravitation the gravitational force between two or more objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
What is newtons second of motion?
Acceleration is proportional to the force applied and inversely proportional to the mass
The amount of acceleration is directly proportional to the force and inversely proportional to the mass?
Yes, that is correct.
How do I find the distance an object is from the earth with only it's mass and weight in it's current position?
You divide the mass by the weight, to get the gravitational acceleration. Then you use the fact that this gravitational acceleration, or gravitational field, is inversely proportional to the square of the distance. The distance should be calculated from the center of the Earth.
Are force and mass directly proportional or inversely proportional?
Force is directly proportional to mass provided the acceleration is constant.
According to Newton's Second Law of Motion acceleration is proportional to force and inversely proportional to?
mass
What causes an object to have a gravitational pull?
Gravitational force between objects is proportional to the sum of their mass and inversely proportional to the square of their distance
What is the gravitational force relating to mass and distance?
Its proportional to the product of their masses, and inversely proportional to the square of their distance apart.
