Question

what does mass and weight of an object mean? class 9​

Answer 1

Answer:

Explanation:

Mass is a scalar quantity. It has magnitude. Weight is a vector quantity. It has magnitude and is directed toward the center of the Earth or other gravity well.

Answer 2

Answer:

Explanation:

Mass does not change on any other place on earth it remains constant always. for example if you have a mass of 67kg on earth your mass on Jupiter will also be 67kg and even on sun it will be 67kg(if you manage to survive..).the SI UNIT OF mass=kg or kilogram

weight depends on the gravitational acceleration of the place. your weight changes on different celestial objects. if your weight on earth is 66Newton your weight on moon will be 66/6=11Newton.

formula for weight=mxg=mass x gravitational acceleration. gravitational acceleration of earth is 9.8ms⁻² or sometimes taken as 10ms⁻².

if mass is 10kg so weight is 10 x 9.8=98Newton or approximately 100Newton.

SI unit of weight is N or Newton
