Yes, a body can have mass but still no weight. Weight W = mg, where m is the mass of the body and g the acceleration due to gravity. g depends on the location and the mass of the planet. g = 0 at the centre of the earth and in space.
At the center point of the earth, the gravity is zero. So at the center of the earth, the weight of the body is also zero. Hence, it is clear that a body can have mass but no weight.
Hence weight of the body is zero at the center of the earth.
Therefore, it is possible for a body to have inertia but no weight.
Humans in many ways follow the principle of inertia. A body in motion is likely to stay in motion, and a body at rest is likely to stay at rest. One of the biggest obstacles to staying in motion is committing to too much and becoming overwhelmed. When it comes to improving, you must learn to change the way you think.
Inertia affects all objects, and all objects have mass. The mass of an objects demonstrates how much matter is within the object. The larger the mass of an object the more inertia it has. Finally, the weight of an object has to do with the the amount of gravity that is being pulled down upon it.
If in some situation, the contact forces on the body are removed, there will be no sensation by any contact forces of the gravitational force on it. Hence, it will be termed as having zero weight or being 'weightless'. This is the case during free fall.
weightlessness, condition experienced while in free-fall, in which the effect of gravity is canceled by the inertial (e.g., centrifugal) force resulting from orbital flight. The term zero gravity is often used to describe such a condition.
Under what conditions our weight becomes zero? Our weight becomes zero when we fall freely under gravity. Also, at the centre of the Earth, weight becomes zero because acceleration due to gravity is zero at the centre of the Earth.
No, there is no matter without weight. The material which occupies space and possesses mass is called matter. Every matter can be divided into three states.
Since an object has infinite kinetic energy when it approaches the speed of light, it therefore has infinite mass as well.
The confusion exists because people factor out the constant g in weighing things on a bathroom scale. In essence they arbitrarily set the scale factor g equal to 1, which is not true it's g = 9.8 meters per second2. In sum: weight is a force, mass is an inertial resistance to force.
Some people have a naturally low BMI due to physical characteristics that run in their family. A high metabolism. If a person has a high metabolism, they may not gain much weight even when eating high-energy foods. Frequent physical activity.
There's fat inside our bodies in places you may not be aware of, like the brain, nerves, and surrounding organs. "It is impossible to have zero percent body fat," says Dr. Sutterer.
The reason we feel weightless is that we're completely free of anything pushing or pulling on us. When we're stood on the ground, the force of our feet on the ground and the ground against our feet is what makes us feel 'weighted'.
If your BMI is less than 18.5, it falls within the underweight range. If your BMI is 18.5 to 24.9, it falls within the Healthy Weight range. If your BMI is 25.0 to 29.9, it falls within the overweight range.
The zero function essentially readjusts the true zero of your weighing scale and lets it know that there is nothing on the weighing pan.
Newton's first law of motion says: inertia is the resistance an object has to change its state of motion. You may remember it better as: an object at rest stays at rest and an object in motion stays in motion unless acted upon by another force.
The dictionary tells us that inertia means "lack of skill, idleness, laziness."
Weight is a force that acts at all times on all objects near Earth. The Earth pulls on all objects with a force of gravity downward toward the center of the Earth.
There are different factors for it : high metabolism, your daily routine, your genes and lastly, the calorie consumption in the whole in different meals. If you think, you eat a meal of 1000 calorie a single meal and then eat 5 chappati the whole day, nothing is going to happen on your body.
The answer is quite simple: they are not in a caloric surplus. We know that in order to gain weight, you have to be in a surplus. In other words, you need to be consuming more calories than you are burning. You can eat only cookies and never gain weight if your calories are low enough.
There are also different tiers of anorexia based on BMI ranging from mild (<17.5), moderate (16-16.99), and severe (15-15.99), to extreme (<15). A BMI below 13.5 can lead to organ failure, while a BMI below 12 can be life-threatening.
