Gravitation pulls everything down (people, rocks, birds, planes..) It takes a force to counter the pull of gravity; in birds' case, it's lift from the birds wing. As air flows past the wing the fact that the length of chord of the upper wing is slightly longer then the length of the chord of the bottom of the wing - this induces a difference in flow speed and creates a slight upward force called lift.
The faster a bird goes, the higher the lift (to a limit.) The longer the wing, the more lift is generated - this is why bird with very long wingspans can travel long distances and go very high compared to birds with shorter wings.*If a bird's wing cannot generate enough lift, the bird will fall to the ground: they must overcome the pull of gravity.
* Note - high speeds are counter to large wings, hawks have shorter and swept vs broad wings on Eagles. The Eagles can go higher and longer, but the Hawks can go faster for short periods of time.

What has a higher gravitational pull the equator or the north pole?
The gravitational pull of the earth is pretty much the same anywhere between the poles and the equator creating a centripetal force pulling things in towards the earth.. However, the rotation of the planet results in an outward centrifugal force pushing things away from the earth. This force is greatest at the equator. Even though the gravitational pull is the same everywhere, the centrifugal force at the equator gives the impression of a very slightly lower gravitational pull.
Which planet has pulling power?
Neptune is the planet that has pulling power.Astronomers noticed that somthing was pulling Uranus from orbiting correctly.They did some research and found out the mystrey planet.
What is Uranus' gravitational pull relevant to Earth's?
uranus's gravitational pull is 91% or earth's.
What is the gravitational pull?
Less than one tenth (1/10) of the earths gravitational pull.
How far from the earth is the gravitational pull of the earth the same as the gravitational pull of the moon?
i dont now
Why the birds and aeroplane are not pulling by gravitational pull of earth?
Because upthrust is greater than gravity, therefore, it stays in the air. Also, the power of the engines/wings hold them up.
What causes an object to have a gravitational pull?
An object has a gravitational pull due to its mass. Gravitational force is a fundamental force of nature that arises from the mass of an object pulling other objects towards it. The greater the mass of an object, the stronger its gravitational pull.
Why do the planets circle the sun?
Planets orbit the Sun due to the gravitational pull between them. This gravitational force keeps the planets in their elliptical paths around the Sun. It is a balance between the planets' inertia wanting to move forward and the Sun's gravitational force pulling them inward.
Why gravitational acceleration decreases when moving earth deep?
As you go down the Earth, there is less matter below you, pulling you down, and more matter above you, pulling you up. (However, the first few kilometers the gravitational force will increase, due to the fact that the Earth is more dense in the center - and you get closer to that center.)
What force does a seesaw use push or pull?
A seesaw uses a combination of gravitational force and the pushing/pulling force applied by the users to create the motion. The pushing and pulling forces result in a torque that moves the seesaw up and down around its pivot point.
What force pulled the satellite down to earth?
Earth's gravitational pull
How can a bird wings and human arm look and function so differently when the same basic tissue that construct them?
Birds Are Made To Fly.Their Wings Are Bigger In Size Than Their Body.Birds Are Of Light Weight And Due To Continuation Of Flapping Of The Wings The Earth's Gravitational Pull To Doesn't Effect Them Too Much,Whereas Human Body Is Heavier Than The Birds,So The Gravitational Pull Pull's Us Down Hence The Humans Can't Fly In The Air
Why does your weight change outside of earth?
Weight changes outside of Earth because weight is a measure of the force of gravity acting on an object. The gravitational pull on an object is determined by the mass of the object and the mass of the celestial body it is on. Therefore, weight will be different on different planets or celestial bodies due to variations in their gravitational pull.
When traveling down a ramp or incline?
When traveling down a ramp or incline, gravity is assisting in pulling you downward. As you descend, your speed will increase due to the gravitational pull. Additionally, friction and air resistance will act as opposing forces, affecting your acceleration and overall speed.
How does the moon effect your weight?
The gravitational pull (gravity) is not as strong on the moon. (It is a smaller object) Since it is not pulling you on to a scale as hard, you do not weigh as much. :)
What happen to gravitational pull of Earth if mass of the object increase or decrease?
The FORCE, or Gravitational Pull of the Earth on an Object is DIRECTLY PROPORTIONAL to the Object's Mass. Force = Mass x Acceleration of Gravity So, if Mass goes up, Pull goes up, If the Mass goes down, the Pull goes down.
What has a higher gravitational pull the equator or the north pole?
