The gravitational pull on an object is known as its weight. The gravitational field is a region in which a mass experiences a force due to gravitational attraction. The gravitational field strength, g, is defined as gravitational force acting per unit mass on an...
When we are comparing the masses of equal volumes of different substances, we are actually comparing their density. The density of a substance is defined as its matter per unit volume. Density = mass ÷ volume p = m ÷ v The SI unit for density is kilogram per cubic...
The mass of an object is a measure of the matter in it. It depends on the number of atoms it contains and the size of those atoms. This property cannot be changed by the location, shape and the speed of the body. The SI unit for mass is the kilogram (kg). Large masses...
