what is the definition of mass of an object
Mass Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied.[1] It also determines the strength of its mutual gravitational attraction to other bodies. The basic SI unit of mass is the kilogram (kg).
The Pale The word pale derives ultimately from the Latin word
Metre per second squared As acceleration, the unit is interpreted physically as change in velocity or speed per time interval, i.e. metre per second per second and is treated as a vector quantity.
Hundreds and thousands Hundreds and thousands used incorrectly instead of hundreds of thousands to mean "an indefinite but emphatically large number".
Momentum In SI units, it is measured in kilogram meters per second (kg · m/s). Newton's second law of motion states that a body's rate of change in momentum is equal to the net force acting on it.
