You could conclude that object a has less kinetic energy than object b. - Object b has a greater inertia than object A
You can conclude many things, but you have to make some assumptions. The conclusion you could make from this limited amount of data is that the two objects are falling, since objects fall at the same rate.
Density = Mass/Volume = 150/6 = 25 grams per cm3.
density = mass/volume = 350/150 = 2.33 grams/cubic centimeter
"Weight" is not measured in kilograms.If your mass was originally 150 kg and you lost 1 kg of mass, then you lost 2/3rds of 1 percent of your original mass.
150 pounds = 68.04 kilograms.
On earth, 150 kg of mass weighs 330.69 pounds (rounded)
mass is how much an object weighs. If you weigh 150 pounds, then you have a mass of 150 lbs (you can say pounds if you want instead of lbs, it is just the abbreviation for pounds). if you weigh 100 kilograms, then you have a mass of 100 kg( you can say kilograms or kilo's if you want, kg is just the abbreviation).
If a person weighs 150 pounds on earth, then his mass is 68.039 kilograms. (rounded) If he weighs 150 pounds on Mars or on the moon, then his mass is a different number of kilograms in each place.
Gravity always works in both directions at the same time. Two masses always attract each other, with a pair of equal gravitational forces than pulls the two masses together. When you stand on a bathroon scale and weigh yourself, you measure the strength of both forces, because they're always equal. If you weigh 150 pounds on Earth, then the Earth weighs 150 pounds on you. When you fall out of a tree, there is a force of 150 pounds that pulls you toward the Earth, and a force of 150 pounds that pulls the Earth toward you. You and the Earth move toward each other until you come together. (Nobody notices the Earth's motion, because the object with the larger mass moves less, and the Earth's mass is about 87,810,000,000,000,000,000,000 times as much as yours.)
A milliliter of water, by definition, weighs one milligram. That is its mass. When 150 mL of water freezes, the volume of the water will change, but the mass will remain the same. So 150 mL of water will weight 150 mg, no matter what state of matter it's in.
Gravity always acts as a pair of forces, not as one single force. The strength of the forces depends on both masses, not just one of them. The forces of gravity attract the diver toward the earth and the earth toward the diver. The forces are equal in both directions. If the diver weighs 150 pounds on earth, then the earth weighs 150 pounds on the diver. The diver accelerates toward the center of the earth with an acceleration equal to (weight)/(diver's mass), and the earth accelerates toward the diver with an acceleration equal to (weight)/(earth's mass). Has that helped, or just confused the issue further ?
The mass and diameter of the planet Mars is less that of Earth so there are changes to how the gravity effects you. This would cause a normally 150 pound person to only weigh 56 pounds on Mars.
You could conclude that object a has less kinetic energy than object b. - Object b has a greater inertia than object A
about 9 pounds
This may be a trick question. We often use the terms "weight" and "mass" interchangeably, but we use the term "weight" to refer to mass that is in a gravitational field (and generally the gravitational field of earth). . If a person weighs 150 pounds, it means that we have used "pound" as a reference, and that involves (or invokes) the effect of the pull of the earth on that person. But that person has mass that is independent of gravitational attraction. A person who has a mass of 150 pounds has that mass no matter where he may be. That person is weightless in deep space where there isn't anything of substance around to exert a gravimetric pull on the person. Mass is present, but there is no weight. . The earth is not said to have weight. Instead, it has mass, and that mass is a bit short of 1024 kilograms. . See an answer to a related question, "What is the weight of earth?"
There are two types of mass, and it turns out that they are physically identical. The first type of mass is defined as a measure of the resistance that an object presents to being accelerated by an applied force. The second definition of mass is a measure of the gravitational force between an object and every other object in the universe. The mathematical expressions for these two (equivalent) types of mass are: 1) m = (F/a), where m is inertial mass, F is the dynamic, pushing force, and a is the acceleration that the mass experiences when the force is applied to it; and 2) m = F * (r^2)/(G * M), where m is gravitational mass, F is the gravitational force of attraction, (r^2) is the square of the distance between the mass and another mass (M), and G is the gravitational constant (6.67 * 10EE-11 in MKS units). Gravitational mass can also be thought of as gravitational charge. It is a remarkable fact that these two apparently very different types of mass, inertial and gravitational, are (as nearly as anyone can tell) absolutely equivalent. Why this so-called Principle of Equivalence is true is, at present, a fundamental mystery. We would understand a lot more about the connection between the large-scale structure of space-time in our universe and the origin of gravity as the quantum mechanical exchange of particles (called gravitons) if we understood why the Principle of Equivalence holds. Mass is an inherent property of a particle or a set of particles. Weight, however, is --not-- the same as mass. Weight is the force that a mass exerts on a scale, and unlike mass it is not an inherent property of an object. Mass is conventionally measured in kilograms (kg), while weight is measured in the U.S. in the English unit of pounds (lb). (The English unit of mass is called a slug.) Unlike mass, weight depends upon where you are: on the Earth (where 1 kg of mass weighs 2.2 pounds), versus on the Moon (where 1 kg of mass weighs 0.37 pounds), versus on Mars (where 1 kg weighs about 1 pound), or in orbit or between planets (where 1 kg of mass weighs nothing). The amount of mass in an object is determined by weighing it in a --known-- gravitational field. To find the amount of mass in an object, weigh it in pounds and then divide by 2.2 to get kilograms. Example: You weigh yourself on a scale and see a weight of 150 lb displayed. What is your mass? Answer: Divide 150 lb. by 2.2 to get your mass in kg. The result is (150/2.2) = 68.2 kg. Some kitchen scales give outputs in units of kg or grams, and likewise some bathroom scales are bimodal and will give results in either sets of units. Be aware that this formula will only work if you are at, or near, the Earth's surface. Different divisors than 2.2 have to be used if you are on another planet. If you are in orbit, the procedure won't work at all because in that situation a mass will produce no weight on a scale. In orbit, you can only find an object's mass by measuring the acceleration, a, that a known force, F, produces on the object and then using the formula m = (F/a) to find the object's mass.
