On earth, it'll be 9.8 meters (32.2 feet) per second2.
In other places, it'll be different numbers.

What is mass multiplied by gravity?
Force or weight Force= mass X acceleration gravity is an acceleration (9.8m/s2) Weight = mass X acceleration due to gravity
What effect of gravitational acceleration on Gravitational constant G?
The gravitational constant, G (big G), is a physical constant that doesn't change at all. The magnitude of gravitational acceleration, g (little g), has no effect on G.Little g is used as an approximation for near-surface gravity of a planet (or other large mass). The reason it is used is because the formula for universal gravity and Newton's second law:F = G (mplanet*mobject)/(r3) -- r is the distance between the centers of massF = mobject*aobjectyields (when set equal and dividing out the mass of the object): aobject = G (mplanet)/r3As you can see, the acceleration due to gravity won't change much for distances near the planet's surface. We call the above magnitude, g. Each planet has its own g and Earth's is about 9.8 m/s2.
What is the gravitational potential energy of an object is equal to its weight multiplied by its?
The gravitational potential energy is equal to: GPE = mass x gravity x height Or equivalently: GPE = weight x height
What is 19.8 meters per second squared?
It is a specific measure of a rate of change of velocity, also known as acceleration. As a rough approximation it is about equal to twice the gravitational acceleration on Earth.
What is the gravitational potential energy of an object equal to?
It is the product of the mass of the object in Kg, the gravitational acceleration which is 9.81 m/sec2, and the height of the object above earth's surface in meters. Result is in Joules
What is the definition of free fall?
when the acceleration of the freely falling object is equal to the acceleration due to gravity then there occurs free fall.
Is mass x gravity equal to an objects acceleration?
Well, first let's look at what gravity is. If we consider "gravity" as gravitational force, then force=mass x acceleration, and mass x gravity does NOT equal acceleration. Acceleration is the change of velocity, so an object could accelerate without being affected by gravity, maybe just another force, like jet engines or something. Basically, no.
As a freely falling object speeds up what is happening to its acceleration due to gravity?
Its acceleration due to gravity is constant. The acceleration is equal to the object's change in speed every second. I've tried to illustrate the constantly-increasing falling speed in my diagram below.
What is a force that can change when acceleration due to gravity cha nges?
That would be the equal mutual gravitational forces between you and Earth, commonly referred to as your 'weight'.
How is the gravitational force FG related to the distance between objects?
Fg is equal to mass times acceleration. While the mass of the object does not change, acceleration (gravity) increases the more the object falls to the ground.
Is fmg the formula that tells the gravitational attraction between m and the earth?
Yes, the equation is Fg = mg. This means that the force of gravity is equal to the mass times the gravitational acceleration (which is 9.8 m/s2). For example, the force of gravity on a 2 kg object would be 2*9.8, which is 19.6 Newtons. (This comes form the equitation F = ma, substituting g, the gravitational acceleration, for a).
Does an object have more potential energy the more mass it has?
Yes - gravitational potential energy is equal to mass x gravity x height.Yes - gravitational potential energy is equal to mass x gravity x height.Yes - gravitational potential energy is equal to mass x gravity x height.Yes - gravitational potential energy is equal to mass x gravity x height.
Sentence describing gravity and weight?
Weight is a force equal to the product of an object's mass and gravity. Gravity in this context is not a force but an acceleration. Near the Earth's surface, that acceleration is 9.8 m/s², regardless of the mass.
Can you create 0 gravity chamber and how?
yes, by creating an opposing acceleration equal to the gravitational field strength (9.81m/s2) this would balance out the force of gravity and u could float. It can be done with magnetism, or with centripetal forces
What is gravitational acceleration equal to?
between 9.78 and 9.82 m/s2
What is mass multiplied by gravity?
Force or weight Force= mass X acceleration gravity is an acceleration (9.8m/s2) Weight = mass X acceleration due to gravity
Are acceleration due to gravity on small stone and big stone equal?
Acceleration due to gravity is the same for every object on or near Earth.
