We know that weight depends on the acceleration due to gravity 'g' and 'g' is inversely proportional to the radius of Earth. The radius of Earth is maximum at the equator. So 'g' is minimum at equator. Hence the weight of a body is minimum at equator.
The mass of a body remains constant but acceleration due to gravity is inversely proportional to the radius of earth. The radius of earth is maximum at equator, hence, acceleration due to gravity is minimum at equator, so, weight of body decreases at equator.
Yes, you weigh less on the equator than at the North or South Pole, but the difference is small. Note that your body itself does not change. Rather it is the force of gravity and other forces that change as you approach the poles.
The weight of the body equals the product of mass and the acceleration due to gravity. This quantity of a body varies from place to place on the surface of the earth. Complete step by step answer: The force by which the earth attracts the body towards its centre is called the weight of the body.
On a friction-less surface, weight of a body would not be zero.
The mass and weight both of a body becomes zero at the centre of the earth.
This is the case during free fall. Neglecting air resistance, there are no other contact forces on a body during free fall and hence, its weight is zero.
Now the weight of the body is directly proportional to the acceleration due to the gravity on the surface of the earth. So the weight of the body is maximum at the poles and minimum at the equator on the surface of the earth. So this is the required answer.
The first heaviest organ is the skin with a mass of four to five kg. The liver is the second heaviest organ in the body, which discharges bile. The weight of the liver is about 1.5 kg. The brain is the third heaviest organ with an approximate mass of 1.5 kg.
As you are nearer to the center of the Earth in death valley r will be smaller thus making the force larger, so you would weigh more in Death Valley than on Mount Everest. However the difference is so small that it cannot be measured easily. Atmospheric pressure will not affect your weight.
Mount Nevado Huascarán in Peru has the lowest gravitational acceleration, at 9.7639 m/s2, while the highest is at the surface of the Arctic Ocean, at 9.8337 m/s2. “Nevado was a bit surprising because it is about 1000 kilometres south of the equator,” says Hirt.
In space without gravity pulling down on them, Astronauts are essentially weightless. It is important to explore the difference between mass and weight. While Astronauts may not weigh anything in space and can float around freely, their body shape and size does not change.
'Centrifugal force' due to the spinning lowers your body weight by about 0.4 per cent at the equator relative to its weight at the poles. The Earth's spin also causes the planet to bulge, so that at the equator you're about 21km further from the Earth's centre of gravity and so weigh around 0.1 per cent less.
Acceleration due to gravity is maximum at poles and minimum at equator as earth is not perfectly round and slightly flat at the poles. Thus, R for poles is least and g=RGM.
An object weighs less at the equator than at the poles because The force of gravity is less at the equator than at the poles as equator is at less distance from the center of the earth in compare to poles.
Skeletal muscle is one of the most dynamic and plastic tissues of the human body. In humans, skeletal muscle comprises approximately 40% of total body weight and contains 50-75% of all body proteins.
Summary. Mass is a measure of the amount of matter that an object contains. Weight is a measure of force that is equal to the gravitational pull on an object. Mass is independent of location, while weight depends on location.
Though your mass stays consistent no matter where you are, your weight can fluctuate. You'd weigh less standing at the equator than you would at a pole.
In vacuum, there is no force of buoyancy, therefore weight is maximum in vacuum.
Bones provide support for our bodies and help form our shape. Although they're very light, bones are strong enough to support our entire weight. Bones also protect the body's organs.
The weight of a body at the centre of earth is zero because value of g is zero. As we move a body closer to the centre of the earth, the mass of the earth between the centre of the earth and the body keeps decreasing.
a) When a body falling towards earth only under the influence of gravity is called free fall. b) As the mass of an object is constant, its mass will 10 kg itself even in free fall. But weight of an object will be zero while it is in free fall.
The weight of the body is also zero in outer space or at the centre of the earth where the gravitational force on the body will be zero. It will just float around.
When the object is falling freely, it is acted upon by the force of gravity. But, the object is not applying its force to any surface. So, the weight of the object is zero.
