What force on an object is caused by the weight of the air above the object?
gravity
How does gravity affect an object in motion?
it pulls the object towards the earth which kind of slows it down i guess. or is that friction? For an object travelling in the Earths atmosphere, or near to the Earth above the atmosphere, gravity provides a force pulling the object towards the centre of the Earth. Unless the object is travelling fast enough, what is called the escape velocity, this gravity force will ultimately cause the object to fall back to the surface. Friction is something else, the friction with the air in the atmosphere also slows the object, but this force acts in opposition to the direction of motion, not towards the Earths centre. To compute the trajectory of the object you need to take both forces into account.
Does gravity pull ONLY down?
No, it pulls in whatever direction the item with the gravitational force is away from the object being pulled. So basically, if there were an object(this object will be marked with a A) just floating and out of no where an object with gravity(Object with gravity being marked with B) appeared ABOVE A, object B would pull object A upward.
Does the force of gravity on an object differ from above and below water?
No. The mutual forces of gravity between the Earth and an object are exactly the same when the object is underwater as they are when it's above water. But when the object is underwater, there's an upward buoyant force on it, which compensates and cancels some or all of the gravitational force.
Why does the area of the base affects stability?
An object is stable if the centre of mass of the object is above the base area. A small perturbation of the object is more likely to push the centre of mass outside the base area if it is small.
What is potential energy called that depends on height?
Gravitational potential energy - it depends on the distance from the centre of gravity, so on Earth it depends on the height above the Earth's surface
Why books did not fall because the the centre of gravity was aligned on what?
horozontal plane above-- sai vineela 8th class, hyderabad
What is an example of unstable equilibrium in sports?
unstable equilibriu is whenthe centre of gravity of a body lies above the point of suspension and supports.
Why not the car engine kept above body?
Because the height of the engine would raise the cars centre of gravity - making it unstable !
When is the pontoon is naturally stable?
When the center of buoyancy is directly above the center of gravity a floating object is stable.
Where should your center of gravity be in relationship to your base of support when lifting an object?
high above the support base
Is the force of gravity the same on an object fifty miles above the earth?
Yes. Gravity is a constant force. It never changes as long as you are within it's pull.
