How can you say that gravitational force is a field force?
It is true that the force of gravity can be described as a force field. Any object having mass will create a gravitational attraction in all directions, with decreasing intensity as the distance from the object increases. Fields are like that. It is different from a force that results from being hit by a baseball, which is exerted only at a specific location.
What happens to the gravitational energy of an object as it gets higher in a gravitational field?
-- If the velocity is horizontal, then gravitational potential energy doesn't change. -- If velocity is vertical and upward, gravitational potential energy increases at a rate proportional to the speed. -- If velocity is vertical and downward, gravitational potential energy decreases at a rate proportional to speed.
What are the two factors that determine gravitational potential energy?
The two variables that determine gravitational potential energy are height above earths surface mass (also air resistance may come into play but in physics friction and air resistance are usually ignored and)
Unit of sound intensity?
The unit of sound intensity I is watts per meter squared (W/m²). Sound intensity is a sound energy quantity. Sound pressure deviations are moving our eardrums. The unit of sound pressure p is pascals (Pa) or newton per meter squared (N/m²). Sound pressure is a sound field quantity. Another answer: The most common unit of sound intensity is the decibel (dB). Reply: No! We got the sound intensity measured in W/m² and the sound intensity level we measure in decibels (dB). The question was "sound intensity".
What is someone who studies magnets called?
A magnetometer is a device used to measure the intensity and direction of a magnetic field.
What is unit of intensity of gravitational field and gravitational potential?
gravatational force
Intensity of gravitational field of earth is maximum at?
at the center of earth
The intensity of the gravitational field inside a hollow spherical shell is?
It is zero.
What does the gravitational field strength on a planet depend on?
It can be calculated on the basis of the planet's mass and its radius.
What is ratio of inertia of mass to given mass is?
This is called the Equivalence Principle. There are many formulas to go with it. But it is basically this: A little reflection will show that the law of the equality of the inertial and gravitational mass is equivalent to the assertion that the acceleration imparted to a body by a gravitational field is independent of the nature of the body. For Newton's equation of motion in a gravitational field, written out in full, it is: (Inertial mass) (Acceleration) = (Intensity of the gravitational field) (Gravitational mass). It is only when there is numerical equality between the inertial and gravitational mass that the acceleration is independent of the nature of the body. -Albert Einstein
What are the factors affecting on weight?
1) the mass of the object. 2) the strength of the gravitational (or acceleration) field effecting it.
What two variables does gravitational energy depend on?
Gravitational energy depends on the masses involved and their distances. For a small (relative to planet-sized masses) mass in a gravitational field, the gravitational potential energy is equal to mgh, where m is the mass of the small mass, g is the gravitational acceleration in the gravitational field, and h is the height of the small mass above the reference surface. This is exactly analogous to the above situation except that the distance has been changed to height above a reference surface in the large (planetary) mass' gravitational field.
Can gravitational be added to electric field to get the total field?
No. The sum of the gravitational field and the electric field is a useless concept.
What two factors determine the potential energy of an elevated object?
Potential energy can be descirbed in many forms: gravitational potential, electrical potential and so forth. For gravitational potential energy, the formula is E=mgh, where E is the gravitational potential energy, m is the mass of the object , g is the strength of the prevailent gravitational field and h is the height above that field. In this instance, the factors determing the potential energy are threefold; the mass, the gravitational field strength and the height. For electrical potential, the factors vary depending on what electrical field, componant or senario you are dealing with. In essence, an object has electrical potential energy when it has become charged (such as an Ion), or it is feeling the effects of conflicting magnetic feilds and motion (as in electro-magnetic induction).
What 2 factors would affect how thick a planet's atmosphere is?
The strength of the planet's gravitational field and exposure to solar wind.
What does the gravitational force between the moon and earth depend on?
Their masses. The strength of a planetary body's gravitational field is directly related to its mass, and its effect on an object is inversely proportional to the square of the distance between the centers of the bodies.
Is gravitational potential energy is the same gravitational force?
No. Gravitational force is the pull an object experience from gravity. Gravitational energy is the energy an object has from its position in a gravitational field. An object moving up in a gravitational field gains gravitational energy.
