The weight of an object is the force of gravity acting on it. In this case, 100 newtons is equivalent to approximately 10.2 kg in weight on Earth.
An object that weighs 100 newtons on or near the Earth's surface has about 10.197 kilograms of mass. It doesn't matter whether it's moving or at rest, or what its speed is. Its motion has no effect on its mass or weight.
It can be said to have no weight, as its weight could only be expressed if it were stationary in the Earth's gravitational field. However its mass (the matter it contains) is about 7.35x1022 kg. This is about 1/80th the mass of the Earth.There is a large distinction between weight and mass. Mass has to do with the amount of matter is in some object, and determines how hard it is to push something around. Weight is how big the force of gravity is that is acting on some object. An object has the same mass no-matter where it is, but its weight depends on being close to the Earth or some other planet. For example, if you were out in space, far away from any planets, you would have no weight since there is no gravity, but your mass would still be the same as it is here on Earth.So, it makes more sense to talk about the mass of the moon than its weight.Relative Weight of ObjectsIt is usually not appropriate to talk about the weight of astronomical objects because the force of gravity varies, depending on the mass of a pair of objects, and their distance from one another. For example, if Earth attracts a table with a force of 100N, then the table attracts the Earth with the same force of 100N (Newton's Third Law), so the weight of Earth - on that table - is 100N. If you took the table millions of miles from Earth, that weight (the table or the Earth) would be much smaller, because the effect of Earth's gravity would be much less.Instead of asking about the weight of objects, compare the objects' masses - those don't change, or hardly change.
a lever has a mechanical advantage of 5 . how heavy an object can the lever move if a person exerts 100N force on the lever?
About 10,18 kg. The relationship between kg and Newtons is kg * 9,8 = N The relationship differs slightly depending on the location. If you want a more accurate answer I suggest searching for how much the constant "g", which I in this case set to 9,8, is in your country.
The weight of any object is a measure of the force that gravity acts upon it, and is measured in newtons (N). The weight is given by: F = m g where m is the mass, and g is the gravitational field strength On Earth, g = 9.8 N kg-1 (approximately) So the mass m = F / g = 100 N / 9.8 N kg-1 = 10.2 kg
100N roughly on earth
The acceleration of the object would be approximately 5 m/s^2. This is calculated using Newton's second law, F=ma, where F is the force of gravity (100N), m is the mass (20kg) and a is the acceleration.
The weight of the body in water is reduced by the weight of the water displaced, which is 100N - 65N = 35N. Therefore, the upthrust on the body is 35N.
The work done to push an object is calculated by multiplying the force applied by the distance over which it is applied. In this case, 100N of force is applied over a distance of 5 meters, resulting in 500 Joules of work done to push the object.
The upthrust on a body in water is equal to the weight of the water displaced by the body. Since the weight of the body decreases by 30N (100N - 70N) in water, the upthrust is also 30N.
