are inertial mass and gravitational mass the same?

Inertial mass measures an object's resistance to being accelerated by a force (represented by the relationship F = ma). Active gravitational mass measures the gravitational force exerted by an object.

One of the greatest sources of confusion in the Imperial (or U.S. Customary) system of measurement is that both mass and force are measured using the same unit, the pound. The differentiate between the two, we call one type of pound the pound-mass (lbm) and the other the pound-force (lbf).

Inertial mass measures an object's resistance to being accelerated by a force (represented by the relationship F = ma). Active gravitational mass measures the gravitational force exerted by an object. Passive gravitational mass measures the gravitational force exerted on an object in a known gravitational field.

As it turns out, these two masses are equal to each other as far as we can measure. Also, the equivalence of these two masses is why all objects fall at the same rate on earth. ... The interesting thing is that, physically, no difference has been found between gravitational and inertial mass.

All objects resist changes in their state of motion. ... Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

The closer one has a greater mass, but the forces from the fans are the same. In the end, the less massive one wins. Since both the acceleration AND the gravitational force depend on the mass, the mass cancels. Objects fall with the same acceleration—if and only if the gravitational force is the only force.

Inertial mass is a measure of how fast an object accelerates--given the same force, increasing the inertial mass implies decreasing acceleration. The simplest way to state the equivalence principle is this: inertial mass and gravitational mass are the same thing.

If we are comparing two different things to each other on Earth, they are pulled the same by gravity and so the one with more mass weighs more. But in space, where the pull of gravity is very small, something can have almost no weight. It still has matter in it, though, so it still has mass.

The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g equal to the conventional value of gravitational acceleration on Earth, g, of about 9.8 m/s2.

Mass is a measurement of the amount of matter in a substance, while weight is a measure of gravity's effect on that mass. ... Mass is measured independently of gravitational force and remains constant no matter where it is measured.

1) Mass is a measurement of the amount of matter something contains, while Weight is the measurement of the pull of gravity on an object. 2) Mass is measured by using a balance comparing a known amount of matter to an unknown amount of matter. ... 3) The Mass of an object doesn't change when an object's location changes.

The main difference between Inertia and Gravity is that the Inertia is a resistance of any physical object to any change in its state of motion and Gravity is a Curvature of spacetime attracting uneven distribution of masses together.

The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.

Mass as we measure it today is a comparative gravity of the earth between the standard unit and the object being measured. Because gravity changes with the size and structure of the object, there is no way to determine the absolute value for the mass of an object.

Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

force = mass * acceleration. So inertia is proportional to mass and the relationship really comes down to the acceleration imparted on a mass by a force based on the above equation.

Inertia is proportional to mass. Big masses resist changing their motion more than smaller masses. Objects at rest remain at rest unless acted on by a net force. A lot of inertia!
