what is the difference between mass and weight class 9
Answers
Answer:
mass is the the thing which occupies space
weight is the force given by an object on earth
Answer:
Hello!
Mass is defined as the amount of matter contained in a physical body.
Weight is defined as the gravitational force with which a physical body is attracted toward the center of the Earth (or other celestial bodies).
Mass is one fundamental property of matter. It is an extensive property.
Weight is not a fundamental property of matter.
Mass has magnitude but no direction, so it is a scalar quantity.
Weight has both magnitude and direction, so it is a vector quantity.
Mass of a body is independent of the location where it is measured.
In fact, a matter has constant mass in the entire Universe.
Weight of a body varies depending on the location of measurement as the acceleration due to gravity changes with location.
Mass of a physical body can never be zero (unless it is moving at the speed of light, rest mass will be zero in such case).
Weight of a body can be zero if the resultant force acting on the same body is zero.
For example, at Earth’s center or in artificial satellite, weight of any matter is zero even though the mass is not zero.Mass is measured using a Pan Balance, inertial balance or Electronic Balance.
Weight is measured using a Spring Balance.SI unit of mass is Kilogram (kg) and CGS unit is Gram (g).
SI unit of weight is Newton (N) and CGS unit is Dyne (dyne).
Since weight is actually a force, so its unit is same with the unit of force.
Dimensional Formula of mass is [M]
Dimensional Formula of weight is [M L T–2].
