Why does an object float or sink?
An object floats when the weight force on the object is balanced by the upward push of the water on the object.
If the weight force down is larger than the upward push of the water on the object then the object will sink.
If the reverse is true then the object will rise – rising is the opposite of sinking..
What is the weight of an object?
In science and engineering, the weight of an object is the force acting on the object due to gravity. Some standard textbooks define weight as a vector quantity, the gravitational force acting on the object. Others define weight as a scalar quantity, the magnitude of the gravitational force.
Why is the weight of an object?
Weight, gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon. … The smaller mass and radius of the Moon compared with those of the Earth combine to make the same object on the Moon’s surface weigh one-sixth the value of its weight on Earth.
What is the weight of a 10 kg object?
Weight varies with location depending upon the acceleration due to gravity eg. for a mass m = 10kg on Earth it`s weight is W = mg = 10 x 10 = 100N.
Why is weight in kg?
However, kilogram (kg) is the mass measuring unit at the International System of Units (ISU). So… … Weight, instead, corresponds to the resultant force of the action exerted by gravity of the Earth (in our case) on the mass of a body, and its measuring unit is Newton (N) at the ISU.
What is the weight of a 40 kg object?
If an object has a mass of 40 kg on Earth it will have the same mass on the Moon. But, on a scale on Earth the 40 kg mass will weigh about 88 pounds. On the Moon it would weight about 14.7 lbs because the gravity there is 1/6 that on the surface of the Earth.
How do you find the weight of an object on the moon?
To find the weight on the moon, we divide the weight on earth by the earth’s force of gravity, which is 9.81m/s2. This calculates the mass of the object. Once we have the object’s mass, we can find the weight by multiplying it by the gravitational force, which it is subject to.
When your mass increases your weight?
As your body grows, you will have more mass, which also means you will weigh more. That’s because when you’re on the earth, the amount of gravity that pulls on you stays the same. So when your mass changes, so does your weight!
What is the weight of a 10 kg object on the moon?
When you ask someone their weight and they say 68kg… they mean 667N. We know this because we are both at the surface of the Earth while we are talking. So a 10kg object weighs about 98N on the Earth and about 16N on the Moon.
What is the weight on moon?
The moon’s gravitational force is only about 16.6 percent of Earth’s gravity. A 45-kilogram person would weigh 100 lbs. on Earth but only 16.6 lbs. on the moon.
How much would a 70 kg man weight on the moon?
Given g on moon=1.7m/s2. mass on earth = mass on moon=70kg. JEE Main could be held 4 times a year from 2021 to reduce the student’s examination stress.
How much would a 60 kg person weigh on the moon?
The force of gravity on her moon is approximately 1/6th thst of earth. So therefore the force or weight of a 60kg mass will be 10kg off weight (not converting to Newton’s ofcourse).
How can I calculate weight?
Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
Why is the weight of an object on moon?
The mass of moon is 1/100 times and its radius 1/4 times that of earth. As a result, the gravitational attraction on the moon is about one sixth when compared to earth. Hence, the weight of an object on the moon is 1/6th its weight on the earth.
What is difference between mass and weight?
In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. In scientific contexts, mass is the amount of “matter” in an object (though “matter” may be difficult to define), whereas weight is the force exerted on an object by gravity.
