Newton showed that, for spherical objects, you can make the simplifying assumption that all of the object's mass is concentrated at the center of the sphere.
What is the weight of the Earth?
100
Gravitational force (N) = mass (kg) x acceleration of gravity 2 (m/s)
What is the Gravitational Force Equation?
100
In Newton’s, which are Kilogram meters per second, or Km/s2. It is measured as a force.
What is gravity measured in?
200
Gravity is an attractive force between any two objects that depends on the masses of the objects and the distance between them.
What is weight in science?
200
2 weight (N) = mass (kg)x gravitational acceleration (m/s )
What is the Weight Equation?
200
We know gravity is caused by mass, but exactly why mass is correlated with gravity is not yet certain.
What causes gravity?
300
A measure of the force of gravity would be the product of mass and the acceleration. The unit of which gravity is measured is called a Newton; one Newton is about the same measure of force as 3.6 ounces.
What is the measure of the force of gravity on an object?
300
Weight is a force and mass is a measure of the amount of matter an object contains.

Pluto was the smallest planet in our solar system before it was reclassified (though Ceres is even smaller, and was considered a planet longer than Pluto). Because the gravity of an object is directly proportional to its mass and density, that would give Pluto the smallest surface gravity.
Which planet has the least gravity?
400
The gravitational force exert on an object.
What is weight in science?
400
Amount of matter in an object.
What is Mass?

Surface gravity is the gravitational acceleration at the surface of an object. For example, the surface gravity of the earth is about 9.8 m/s^2.
What is surface gravity?
500
It is the ratio of the density of a material to that of water at 4 degrees Celsius.
How is Specific Gravity defined?
500
Gravity does not generally affect sound. Gravity can cause materials (like certain gases in air) to be compressed because of a difference in density. And as we know, more dense materials usually conduct sound better than less dense materials. But we generally don't see gravity as a factor in anything to do with sound.
Does gravity affect sound?

It affects the earth’s surface by making all objects stay on the earth’s surface.
