The acceleration due to gravity in the neighborhood of some mass is:
A = G m/R2
A = the acceleration of gravity
m = the mass of the mass
R = your distance from its center
==> G is the "gravitational constant".
Without it, you would know that the acceleration is 'proportional' to the mass of the mass, and 'inversely proportional' to the square of your distance from it. But you couldn't calculate an actual number without a 'proportionality constant'. That's what 'G' is.
The gravitational constant is a universal number that applies equally in all places, at all times, and upon all objects. It is expressed as:
6.67300 × 10-11 m3 kg-1 s-2
Acceleration due to gravity is the phenomenom in which all masses are attracted to all other masses. The force due to gravity is expressed as:
- Fg = Gm1m2/R2
where:
- Fg is the force due to gravity;
- G is the universal gravitational constant, above;
- m1 is the mass of the first object;
- m2 is the mass of the second object; and
- R is the distance from the centers of the two objects.
Acceleration is expressed as
- Ag = Fg/m1
where:
- Ag is the acceleration due to gravity;
- Fg is the Force due to gravity, from the equation above; and
- m1 is the mass of the object being accelerated.
Subsituting the equation for the force due to gravity (Fg) in the above equation for acceleration due to gravity (Ag), we get:
- Ag = Gm2/R2
Remember that m2 is the mass of the other object (say, planet Earth). Notice, too, that m1 (your mass) cancels out completely. So the acceleration of your body due to gravity depends on the mass of planet Earth, but does not at all depend upon you own mass, or weight. That means that all things, regardless of how heavy or light, experience the same acceleration due to gravity at sea level on planet Earth.

What is the difference between gravitational acceleration and acceleration?
Gravitational acceleration is simply acceleration due to gravity.
How are constant speed and constant acceleration different?
There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.
Difference between rate constant and specific rate constant?
There is no difference between them they are same rate constant is another name of specific rate constant
What is the difference between a constant in a graph and a constant in a experiment?
the difference between a constant in a graph and a constant in a experiment is that when on a graph, the constant is the thing that changes, and in a experiment it is the part that stays the same.
What apparatus was used by Cavendish to discover the universal gravitation constant?
The gravitational constant denoted by letter G, is an empirical physical constant involved in the calculation(s) of gravitational force between two bodies
What is the difference between gravitational acceleration and acceleration?
Gravitational acceleration is simply acceleration due to gravity.
What is the difference between uniform acceleration and constant acceleration?
Uniform acceleration refers to a situation where an object's velocity changes by the same amount in each unit of time. Constant acceleration, on the other hand, means that the object's acceleration remains the same throughout its motion. Uniform acceleration leads to a constant increase in velocity, while constant acceleration implies that the rate of change of velocity remains consistent.
Differentiate between universal gravitation constant abbreviated as G and acceleration due to gravity abbreviated as g.?
The universal gravitation constant (G) is a fundamental constant that appears in the law of universal gravitation, which describes the gravitational attraction between two objects. On the other hand, acceleration due to gravity (g) represents the acceleration experienced by an object in a gravitational field, typically near the surface of a massive body like Earth. The value of G is constant and the same throughout the universe, while the value of g can vary depending on the mass and radius of the celestial body.
How do you find acceleration due to gravity when gravitational constant is given. tell the formula?
The formula to find acceleration due to gravity (g) is g = G * M / R^2, where G is the gravitational constant, M is the mass of the attracting body, and R is the distance between the center of mass of the attracting body and the falling object.
How are constant speed and constant acceleration different?
There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.
What is the difference between constant speed and constant acceleration?
Constant speed means moving at a steady rate without any change in velocity, while constant acceleration means changing the velocity by the same amount in each unit of time. In other words, constant speed is uniform motion, while constant acceleration is when the velocity is changing at a constant rate.
What is the relationship between acceleration and mass when mass is constant?
i think... acceleration is constant but im not sure
What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
What is the difference between constant and non-constant motion?
Constant motion is when an object maintains a steady speed and direction over time, like a car driving at a constant speed on a straight road. Non-constant motion is when the speed or direction of an object changes over time, such as a car accelerating or turning.
What is interacting in a gravitational interaction?
Two particles are interacting in a gravitational interaction. It could be an two atoms, to electrons, or even to celestial bodies. The force of interaction between these two particles is directly proportional to its mass, and the constant of proportionality is the acceleration.
What is the difference between an object with constant acceleration and an object with constant speed?
Constant speed means that the speed doesn't change.Constant acceleration means that the acceleration doesn't change. The velocity WILL change in this case - unless the acceleration happens to be zero. So will the speed - note that in circular motion, both the acceleration and the velocity change all the time, even if the speed doesn't change.
How does the weight of an object affect the rate of it's fall?
It doesn't. Acceleration in gravitational field depends only on the attractor's mass and distance to its center. a = GM / r, where: G - gravitational constant, M - mass of attractor, r - distance between bodies.
