What is the definition of force of gravity?
Gravity is one of the fundamental forces in the universe. A force is the product of the mass and the acceleration of that mass. On earth the acceleration due to gravity is around 9.81 metres per second per second. Mass is how much kilograms are involved. Therefore the force of gravity on earth is 9.81 x mass. If the units are metres/second squared AND kilograms the force of gravity will be in Newtons.
Is force of gravity increasing or decreasing?
Gravity is mediated (i.e. comes from) a particle known as a graviton. Now, the force of gravity on earth neither increases or decreases, it does however vary depending upon your geographic position. Despite this, the values of gravity all center around the average of 9.81 meters per second per second (remember that gravity is a downward force causing an acceleration).
Does the force gravity speed up the period of a pendulum?
At greater gravitational force, the frequency (the number of cycles per second) will be higher.
What is the measurement of the force of gravity called?
Gravitational pull is measured in m/s (meters per second). For example, Earth's gravitational pull is 9.8 m/s/s, or 32 feet per second per second. Weight is similar to gravity, as weight is the measure of the gravitational pull upon an object. This force is measured in Newtons.
What is earth's acceleration of gravity?
Acceleration of gravity states that all objects, no matter what the size, will fall at the same rate. This is the rate at which objects free-fall.
What is the force of gravity on an object know as?
The force of gravity on any object near the surface of the earth and close to sea level is 9.80 meters per second per second.

What is the force of gravity of venus at the surface?
The force of gravity at the surface of Venus is 8.87 meters per second per second, or 8.87 meters per second squared. If you weighed 100 pounds on Earth, you would weigh approximately 91 pounds on Venus.
What is the gravity force of mercury?
The surface gravity of Mercury is 3.7 meters per second squared. The Earth gravity is 9.8 meters per second squared. Comparing these quantities, you find that Mercury' gravity is approximately 38 percent that of the Earth's.
SI unit for force of gravity?
Gravity is a form of acceleration and so is measured in metres per second^2.
What is the measure of the force of gravity that is expressed in newtons?
Standard gravity is measured as 9.8 meters per second squared. This is then multiplied by the mass of something to get the force of gravity on it, which is expressed in Newtons.
What is gravity greater then?
The acceleration due to gravity is 9.81 meters per second. Since Force = Mass x Acceleration, the force of gravity would be the mass times 9.81.

Who invented a unit of gravity?
Nobody invented gravity, or 'a unit of gravity'. Gravity has been around since time began. Arguably, Sir Isaac Newton was the first person to realise the existence of gravity, and its implications.The most commonly used unit of gravity is the 'gal' or galileo, equivalent to 1cm per second per second. Under the SI system, the standard unit of acceleration is 1 m per second per second.Gravity can also be expressed in units of force, usually the newton (the force needed to accelerate 1 kilogramof mass at the rate of 1 metre per second per second).
Surface gravity on Venus?
The force of gravity at the surface of Venus is 8.87 meters per second per second, or 8.87 meters per second squared. If you weighed 100 pounds on Earth, you would weigh approximately 91 pounds on Venus.
What will be the acceleration due to gravity or its surface when earth contracts half of its present size without change its mass?
The current acceleration due to gravity is 32 feet per second per second, or 9.8 meters per second per second. The "inverse square" equations for gravity and distance indicate that if the mass remains constant while the radius is cut in half, the force of gravity would increase by a factor of four. So the new acceleration due to gravity would be 128 feet per second per second, or 39.2 meters per second per second.
What is the force that accelerates objects at 9.80665 meters per second squared towards Earth?
