What would happen to your mass if you went to the Moon?
A: Our weight on moon is less than it would be on Earth due to a difference of the strength of gravity on the moon. This means that if you went to the moon you would weigh less, even though your mass stays the same!
What does the difference between your weight at the equator and your weight at the poles?
The equator is moving quickly as the earth’s spins, so it has a lot of centrifugal force. The centrifugal force at the poles is zero. Your total weight at sea level at the equator (gravity minus centrifugal force) is therefore 9.764 m/s2 times your mass, whereas your weight is 9.863 m/s2 times your mass at the poles.
How does your weight change at the equator?
‘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.
Will your weight change when you go to the Moon?
Since the Moon is smaller than Earth, it has a weaker gravitational pull. In fact, the Moon only has 1/6 the gravity that Earth does. This means you weigh six times less on the Moon than you do on Earth! When the astronauts landed on the Moon in 1969, they wore space suits and carried heavy packs of equipment.
How would your mass on the moon compare to your mass on Earth?
Your weight on the Moon is 16.5% what you would experience on Earth. In other words, if you weighed 100 kg on Earth, you would weigh a mere 16.5 kg on the Moon. The mass of the Moon is only 1.2% the mass of the Earth, so you might expect it to have only 1.2% of the gravity.
How would mass and weight differ on the moon?
It is also defined as the force of gravity acting on the object. Therefore, the mass of an object on the Moon remains the same as its mass on Earth. But its weight gets less because the gravity on the moon is less than on the Earth.
What is difference between mass and weight?
Mass is a measure of how much force it will take to change that path. Mass depends on how much matter – atoms and so on – there is in an object; more mass means more inertia, as there is more to get moving. Weight, on the other hand, is a measure of the amount of downwards force that gravity exerts on an object.
What is relation between mass and weight of body?
The mass of an object is a measure of the object’s inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
Why a body weighs more on equator than on pole?
The weight of a body depends on the force with which it is attracted towards the centre of the Earth. But this force is greater at the pole on account of less distance from the centre of the Earth. Due to this, the body weighs more at the poles than at the equator.
Does the Moon have more mass than Earth?
The Earth’s Moon has considerably less mass than the Earth itself. Not only is the Moon smaller than the Earth, but it is only about 60 percent as dense as Earth. Thus, the gravitational attraction on the Moon is much less than it is here on Earth, and a person weighs less on the Moon.
Does your mass change on different planets?
Our mass is the amount of matter that we consist of. This mass does not change when we change planets. However, if we went from Earth to Mars, our weight would change because Mars has less gravity than Earth. So, a small planet has less and larger planet has more gravity.
Why does the equator weigh less than the Poles?
You are right, that because of centrifugal force you will weigh a tiny amount less at the Equator than at the poles. Try not to think of centrifugal force as a force though; what’s really going on is that objects which are in motion like to go in a straight line and so it takes some force to make them go round in a circle.
Mass does not change according to location. Weight varies according to location. Mass is a scalar quantity. It has magnitude. Weight is a vector quantity. It has magnitude and direction. The direction is toward the center of the Earth or other gravity well. Mass may be measured using an ordinary balance.
How is the mass of a person measured?
Weight is measured using a spring balance. Mass is measured in grams (g) and kilograms (kg). Weight is measured in Newtons (N). We tend to measure weight in grams, kilograms, ounces, and pounds. Technically, grams (g) and kilograms (kg) are units of mass. The SI unit of force is the Newton (N), with a 1 kg mass having a force of 9.8 N on Earth.
Is the weight of an object always the same?
Mass is a property of matter. The mass of an object is the same everywhere. Weight depends on the effect of gravity. Weight increases or decreases with higher or lower gravity. Mass of an object can never be zero. Weight can be zero if no gravity acts upon an object, as in space.
