Question

Whats the force excerted on objects by earth's pull?

Answer 1

Folks.... gravity is NOT a FORCE.... it's a special term for acceleration due to a large body like earth..

The simple answer is WEIGHT.

The force that the earth pulls objects towards it is called..Weight.  It's calculated by

W = m*g   (which is the same form as Newton II ...  F = m*a, and we're replaced a with g)

Now this is only true for objects close to the earth's surface.  If the object is further out... say in space, you would have to use Newton's Universal Gravitation formula..

F = GMm/d^2

were G is the universal gravitaton constant.

M is mass of Earth,

m is mass of object

and d is separation distance (theoretical centre to centre)

Answer 2

gravity dude.

oh and to the guy above me freefall is 9.81 m/s ^ 2

but you know 10 is rounded up

Answer 3

it is whatever the mass of the object times 9.8.

make it a good day

Answer 4

The force exerted on an object by earth's pull = It's Weight.

When an unbalanced force is applied to an object, the object will accelerate. The size of the acceleration depends upon the force applied and the mass of the object. There is a relationship between force, mass and acceleration (force = mass × acceleration).

Gravity is a force that attracts objects with mass towards each other. The weight of an object is the force on it due to gravity. There is a relationship between weight, mass and acceleration of free-fall (weight = mass × acceleration of free-fall). The gravitational field strength of the Earth is 10 N/kg and its acceleration of free-fall is 10 m/s2.

Answer 5

it is -9.8m/s^2 or 9.8m/s^2 down. Gravity is a vector quantity which means that it has to have a direction associated with it. If you forget to consider the negative it can mess up your entire question.

Answer 6

it is equal to mass of the object times the gravity( 9.8 m/s/s)

Answer 7

According to Newton it is gravity.
