Are gravity and magnetism examples of contact forces?
They're both great examples of NON-contact forces. Two objects do NOT needto be touching in order to be affected by gravitational or magnetic forces.
What would cause the force of gravity acting between two objects to be four times greater?
There are two ways to do that:-- Make the product of their masses four times as great.-- Make the distance between their centers halfas far.
Why are force fields necessary to describe gravity?
Electic Force At A Distance By Jhon
What is the relationship between density and specific gravity?
There is a very great relationship between density and specific gravity. Density contributes to the weight of a substance under specific gravity.
How does distance affect the force of gravity between 2 objects?
The farther apart two objects are, the less the gravitational force between them. Gravity gets weaker with distance. To be specific, it decreases by the square of the distance. If you double the distance (multiply the distance by 2), the force of gravity is 1/22 or 1/4th as great as it was. If you triple the distance, the force is 1/32 or 1/9th as great, and so on.
Is Mars filled with gravity?
Filled with gravity? It does have gravity, just not as great as Earth's since it is smaller. The greater an object, the more gravity it has to pull objects close to it.
The weight of an object is based on what?
Its mass and the gravity of the objects that are close enough to it to have a great effect on it.
Is it true that Gravity exists between two objects but only when they're close enough to affect each other?
Not quite. Gravity can act at any distance. However, in practice, when the distance between the objects is great, the force of gravity may become insignificant.
Why don't you feel the pull of gravity when you hold an open book?
because the mass of the 2 objects is to great
The force of gravity acting on an object is the objects what?
All mass attracts all other mass, thats a fact. The force between two independent masses depends on the total mass and the distance between them. The "cause" of gravity is subject to great debate, even today.
Why do lighter objects fly slower than heavier objects?
they have less mass. heavier objects have a great mass so it gets pulled down faster..... by a little thing called......gravity!
How are planets and sun are alike?
They tend to be round, spherical objects which are visible in space. They have great mass and their own gravity.
What determines how great a force gravity will place upon an object?
-- The gravitational force is always a two-way thing. It acts between two objects, on the line between their centers. The force on each object attracts it toward the other one, and the forces on both objects are always equal. -- The strength of the force depends on ===> the product of the masses of the two objects. Bigger product = more force. ===> the distance between their centers. Bigger distance = less force.
How does the distance between objects affect the gravity them between?
The farther apart two objects are, the less the gravitational force between them. Gravity gets weaker with distance. To be specific, it decreases by the square of the distance. If you double the distance (multiply the distance by 2), the force of gravity is 1/22 or 1/4th as great as it was. If you triple the distance, the force is 1/32 or 1/9th as great, and so on.
Why does earth not have zero gravity?
Because it has great mass, subatomic particles, called gravitons, cause it to attract all objects near it
What attracts a great horned owl?
Its prey.
What attracts great white sharks?
