The weight of an object on Earth is the same as its mass, which is 1kg in this case. Weight is a measure of the force of gravity acting on an object's mass.
The mass is twice as much, so multiply by 2. The radius is 3 times as much--the gravitational force is inversely proportional to the square of the radius, so multiply by 1/9.2 X 1kg/9 = 0.2 kg.
The weight of a 1kg object on the surface of the Moon would be approximately 1/6th of its weight on Earth. This means the object would weigh about 0.1667 kg on the Moon due to the Moon's lower gravity compared to Earth's.
The center of mass of an object is the point at which its mass can be considered to be concentrated. It is the average position of all the mass in the object. It is the point around which the object will balance in any orientation.
The object's mass doesn't change, no matter where it is or where it goes.
The weight of an object on Earth is the same as its mass, which is 1kg in this case. Weight is a measure of the force of gravity acting on an object's mass.
The 2kg brick has more inertia than the 1kg brick. Inertia is directly proportional to an object's mass, so the higher the mass, the greater the inertia.
Mass is the measure of the amount of material in the object being directly related to the number and type of atoms present in the object. Mass does not change with the body's position, movement or alteration of its shape unless material is added or removed. The weight of the object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity. Since the weight is a force, density is mass/volume. If an object has a mass of 1kg on Earth is would have a mass of 1kg on the moon even though it would weigh 1/6th. as much. Mass is inertial property
To move a 1kg object, you need to apply a force equal to its mass multiplied by its acceleration. The force required to move a 1kg object will depend on the acceleration you want to achieve. This relationship is described by Newton's second law of motion, which states that force is equal to mass times acceleration (F=ma).
The weight of any object is caused by the gravitational field of the nearest, large object. For a 1kg mass on the Earth its weight is about 10 Newtons. On the moon, the same 1kg mass would have a weight of about 2 Newtons.
Strictly, kg (kilogrammes) is a unit of weight rather than mass, which is measured in N (Newtons). This is important, because the MASS of an object does not change, whereas its WEIGHT does change according to the gravitational pull it is experiencing. On earth 1kg is about 10N. On the moon, say, something weighing 1kg would have a MASS of a little over 60N. If we change the word 'mass' in your question to 'weight', then the answer would be 'anything greater than 5kg'. If not, then 'anything greater than 50N subject to gravitational forces on the Earth's surface'. An object's INERTIA is the force that must be overcome in order to change its position (if stationary): so, it is clearly easier to move a 5kg object than it is to move any object that is heavier.
The momentum of an object with a mass of 1 kg and a velocity of 10 m/s is 10 kg*m/s. Momentum is calculated by multiplying the mass of the object by its velocity.
Neither! They both have the same mass of 1 Kilogram.
It is: 5kg-1kg = 4kg
The weight of 1 kg is 1 kg on Earth. If the force is to be determined, it is 9.8 Newtons due to gravity.
The mass is twice as much, so multiply by 2. The radius is 3 times as much--the gravitational force is inversely proportional to the square of the radius, so multiply by 1/9.2 X 1kg/9 = 0.2 kg.
None. The mass of an object won't change if you change the state of matter. When you burn it, the mass can change, since the atoms of the original object combine with oxygen, usually.
