Mass, Weight and Gravity by Ron Kurtus - Physics Lessons: School for Champions
Study the solar system and how gravitational forces work with BBC Bitesize KS3 The weight of an object depends upon its mass and the gravitational field strength. of an object is the gravitational force between the object and the Earth . The weight of an object is the force on it due to gravity. There is a relationship between weight, mass and acceleration of free-fall (weight = mass × acceleration . The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force.
What is the relationship between force and gravity? | How Things Fly
Mass is the amount of matter. The metric or SI unit of mass is the kilogram. The English unit of mass is the slug or pound-mass. The units of weight are units of force.
Astronomy and space science
The English unit of weight is the pound lb. See Confusion about Mass and Weight Units for more information. Measuring weight A spring scale is often used to measure an object's weight. Again, Hooke's Law is applied.
The displacement a spring is stretched for a given force or weight is first calibrated. Then you can use the spring scale to measure the weight of various objects.

Within a range of weights, the weight is proportional to the displacement stretched. Weight on the Moon The mass of an object—or the amount of matter it contains—is the same on the Moon as it is on the Earth.
However, the weight of the object is a function of the acceleration due to gravity. Summary Gravitational mass of an object is determined by using a balance scale to compare its mass with a unit mass. Inertial mass is the measurement of the mass of an object measured by its resistance to acceleration.
Mass and Weight - Definition, Relation, Difference & Effects of Gravity | [email protected]
Gravitational mass and inertial mass have been shown to be equivalent. Weight is defined as the force of gravity on a mass. It is the amount of force required by a body of mass one kilogram to produce an acceleration of one meter per Second Square Dyne is the CGS unit of force.
It is the amount of force required by a body of mass one gram to product an acceleration of one centimeter per square second Relation between Newton and Dyne: There is no effect of gravity on mass. It remains the same be it on Earth or any other planet like Moon even though the acceleration due to gravity value keeps on changing at different planets Effect of gravity on weight — Weight is how heavy an object is in a gravitational field.
The weight of a body keeps on decreasing at higher altitude where it is furthest away from the center of gravity of Earth. They are directly proportional to each other.
Mass is defined as the amount of matter with which it is made up of, regardless of its configuration or any force acting on the body.
Mass and force
Weight is the computation of the force of gravity acting on a body and it depends on the value of acceleration due to the gravity of the place in which the body resides. Mass of a body being constant at any place is unaffected by the gravity whereas weight of an object is directly proportional to the value of gravity of that place. S unit of mass is kilogram and gram respectively whereas that of weight is Newton and dyne respectively. Device used for measurement:
