The potential energy of an object depends on its?
... the masses of the bodies involved and the distance between them.
A satellite is projected vertically from an Earth station at what height above the Earth's surface will the force of Earth's gravity on the satellite be only half its value at the earth station?
To answer this question we need to know either the height of the Earth station above the Earth or the gravitational acceleration of gravity present at the Earth station initially.Solving without these values:(1/2)Gm/R2 = Gm/r2whereG is the Gravitational Constantm is the mass of the EarthR is the radius of the Earth Station from the center of the Earth.r is the radius of the satellite where gr=1/2ge2R2 = r2SQRT(2)R=r
How Johannes Kepler found the value of gravitational acceleration?
He didn't. It was first measured by Henry Cavendish in 1798. He used a torsion balance invented by John Mitchel. Google "Cavendish Experiment" for precise details.
Which is more useful to scientists the Richter scale or Mercalli scale?
The scales have differing uses and so which scale is more useful depends on exactly what the scientist is interested in. The Richter scale is a magnitude scale. This is an estimate of the amount of energy released by an earthquake. The Mercalli scale is an intensity scale. This is an estimate of the perceived severity of ground shaking in differing areas caused by an earthquake. The Richter value is derived based on the amplitude of seismic waves measured on a seismometer and a single value is calculated for a given earthquake. This allows an earthquake to be compared to other earthquakes. The Mercalli intensity value is derived based on the damage caused to buildings and other structures and also based on the measured ground acceleration at a given location. This value can vary depending for a given earthquake on the local ground conditions, the distance from the earthquakes epicentre and the earthquake resistance of buildings. As such, the Richter value is most useful for comparing one earthquake with another, the Mercalli value is most useful for comparing the severity of ground shaking and damage caused by a single earthquake in different locations.
What is oil graded based on?
Oil is graded based on its viscosity and density, which are often measured using the American Petroleum Institute (API) gravity scale. The viscosity indicates how easily the oil flows at specific temperatures, while the API gravity provides a measure of the oil's density compared to water. Additionally, oil can be classified by its sulfur content, distinguishing between sweet (low sulfur) and sour (high sulfur) crude oils. These factors help determine the oil's quality, market value, and suitability for various refining processes.
How do you calculate the acceleration of gravity?
The acceleration of gravity can be calculated using the formula a = 9.81 m/s^2, where "a" represents the acceleration due to gravity. This value is a constant for objects falling in Earth's gravitational field.
How acceleration due to gravity value is calculated?
The acceleration of gravity due to a single object is(Universal gravitational constant) x (Mass of the object)/(distance from the object's center of mass)2
What is the value for acceleration from gravity?
The value for acceleration due to gravity on the surface of the Earth is approximately 9.81 m/s^2.
The acceleration due to gravity at the equator?
about 9.795m/s2 but9.8m/s2 is almost always used.Note: centripetal acceleration (from the earth's spin) cause apparent gravity to be about 0.3% less than actual gravity (about 9.767m/s2) at the equatoryou can find the acceleration of gravity on any planet by the equation:a=G(M/R2) where 'a' is the acceleration due to gravity, G is the gravitational constant (about .0000000000667), M is the mass of the earth ( or other planet), and R is the radius of the earth (or other planet)References:A.P. Physics class
Is Mercurys gravity stronger or weaker than earth?
The acceleration of gravity ... and therefor the weight of any object ... on thesurface of Mercury is 37.698% of its value on the surface of Earth. (rounded)
What is the percentage error in the determination in acceleration due to gravity percent error in physics?
The percentage error in determining the acceleration due to gravity is calculated by taking the absolute difference between the measured value and the accepted value, dividing this difference by the accepted value, and then multiplying by 100 to get a percentage. This error percentage helps to assess the accuracy of the measurement compared to the theoretical value of acceleration due to gravity (9.81 m/s^2 on Earth).
What is the value in meter per second of the acceleration of gravity?
9.8
What do you expect the value of the acceleration of gravity to be?
9.81
What is the value for the acceleration due to gravity?
9.98
Who discovered the value for acceleration of gravity?
The value for acceleration of gravity was discovered by Sir Isaac Newton in the late 17th century. He determined that the acceleration due to gravity near the surface of the Earth is approximately 9.81 m/s^2.
Does changing the mass of a free falling body affect the value of the acceleration of gravity?
No, changing the mass of a free-falling body does not affect the value of the acceleration due to gravity. The acceleration due to gravity is a constant value that is independent of the mass of the object. All objects fall at the same rate in a vacuum due to gravity.
Upon what factors value of g depends?
The value of the acceleration due to gravity (g) depends on the mass of the planet and the distance from the center of the planet. It is inversely proportional to the distance squared and directly proportional to the mass of the planet.
