The gravitational force between two objects is given by:
F = GMm/r²
F = force, G = gravitational constant, M and m are the masses, r = distance between the objects.
The force is dependent on only the masses of the objects and the distance between them. It is not dependent on the temperature of the objects.
Choice B
Answer:
force = mass * acceleration
therefore the SI unit is kg*m/s2 or newton's
it's a vector quantity because it has both direction(acceleration) and size (mass)
Answer:
18 grams
Explanation:
The mass of an object is the object's fundamental property. It is the amount or quantity of mater in the object. Irrespective of the object's location or the gravitational force applied on the object, the mass of an object remains the same. In other words, the mass of an object is the same everywhere.
The mass should however not be confused with its weight which depends on the mass and the gravitational force applied on it.
In summary, whether on earth or in the moon, the mass of an object remains the same. If the mass of the object is 18 grams on earth, it will also be 18 grams in the moon.
