Identify each statement as either true or false 1.) the greater the mass, the greater the gravitational pull. 2.) gravitational pull decreases with an increase in the distance between two objects. 3.) if there were no gravity, planets would collide with another one. 4.) am objects mass is less on the moon than it is on earth. 5.) the momentum of moving planets does not depends on their masses. 6.) the sun revolves in an orbit within our galaxy

The greater the mass, the greater the gravitational pull.  True.

Gravitational force is the attractive force applied on an object by the earth, which is equal to the mass of the object.

Gravitational forces is directly proportional to mass of object.

Hence greater the mass, greater the gravitational force.

Gravitational pull decreases with an increase in the distance between two objects. True.

Gravitational force depends upon the two factors:

Distance, between the object and earth.

Mass of the object.

Gravitational force is inversely proportional to the sequre of distance.

Hence increase in distance will lower the gravitational pull.

If there were no gravity, planets would collide with another one. True

As the gravitational pull on planets is the attractive force on planets by sun.

Due to which each planet is moving in distinct separated path.

As if there is no gravitational pull the planet will be no more in any path.

They will move randomly, colliding each other.

An objects mass is less on the moon than it is on earth. True

As the gravitational mass depends upon the mass and moon has less mass than earth.

Its gravitational force will also weak, it will attract object with less attraction, making mass of object less.

Because gravitational force is the attractive force applied on an object by the earth, which is equal to the mass of the object.

That's why an object on moon will has less mass than earth.

The momentum of moving planets does not depends on their masses. False

The momentum in moving planets is known as angular momentum.

Angular momentum = mass × velocity × distance

So according to above formula momentum is directly proportional to mass.

Hence statement if false statement.

The sun revolves in an orbit within our galaxy. True

Yes, sun revolves around the center of milky way galaxy.

The shape of milky way galaxy is spiral shape and we are moving aroun this galaxy's center at the speed of 828,000 km/hr.

It takes 230 million years to make one complete orbit around the Milky Way at high rates.

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.
