Does gravity zero at equator according to centripetal force explain?

gravity provides pretty much the same force on a given mass anywhere on earths surface, due to its mass only and irrespective of earth spin.
example:
say your 70 kg mass at equator (where centripal action is greatest)
force due to gravity : f = (G*m1*m2)/d^2 = 687.4 newtons
force due to centripetal action at equator :
f = mass * (v^2/r)= 70*0.034 = 2.38 newtons

Where is gravity strongest equator or north pole?
Force of gravity is proportional to the masses and inversely proportional to the square of the distance. Only considering the force of gravity, it is larger at the equator. If you measure the weight of an object, however, countering gravity is the centripetal force of rotation, which will "subtract" from the force of gravity at the equator.
Why is gravity stronger at the poles than the equator?
The closer an object gets to the center of the earth, the greater the pull of gravity on that object.
How does rotation affect the value of gravity at the earth surface?
The (centripital) force due to rotation is at its greatest at the equator, if you weigh 100 kg, the force of gravity on you = approx. 982 n anywhere on earths surface, the centripetal force at the equator = 3.4 n
Is Gravity is example of a centripetal force?
It can be. A centripetal force is not fundamental (such as gravity), it is the generic name given to a force that keeps objects moving in orbits (or circles). In the case of the Sun and the Earth, gravity is the centripetal force that keeps the Earth in orbit around the Sun.
The amount of force exerted on an object due to gravity?
Centripetal
What are the scientific forces?
Support, gravity, friction, thrust, centripetal.
How does Gravity shape earth?
Originally earth was a weightless liquid blob, which will default to a spherical shape, add to this the rotation and centripetal swelling at the equator which flattens the poles, then after cooling and solidifying, this pretty much is earth today.
What centripetal force that causes it to move in a circle?
gravity or gravitational pull
Which force acts on a moving car negotiating a bend?
Gravity and centripetal for
What provides the centripetal force that keeps objects in orbit?
Centripetal force wants to move something towards the centre. So in a satellites case that would be the Gravity of the Earth. If you had a rock tied to a string you were spinning around, the Centripetal Force would be the tension in the string acting towards the centre.
Gravity provides a centripetal force on the Moon helping it stay in orbit around Earth?
Gravity provides a centripetal force on the Moon, helping it stay in orbit around Earth. TRUE!!! -iRLANDA♥
What is the gravity percentage on Mars?
Martian gravity is only 38% of the Earth's gravity.
