Nigeria was colonized by Britain in the late 19th century. In 1960 Nigeria regained independence, but unfortunate fell into a civil war. Nigeria has had a series of alternately military Dictatorship or democratic government. Nigeriaâ??s 2011 presidential election more or less solidified its democratic government.
there are many forces that can act in an upward direction, but most of them (conceptually) are related to "normal force", the force that prevents gravity from breaking a desk every time a book is set on it.
normal force is the force of resistance to change: it comes down to the attractive force in the molecular bonds of the (ie) desk. because the molecules in the desk require force to break and the force of gravity from the book is not great enough to overcome that, the desk stays intact.
other examples of molecularly-based upward forces are air resistance of falling objects and buoyancy.
There are many of those: you can pull something up with a string, push it up with your hands or some equipment, lift things with magnetic or electric forces, blow it upwards (blowing air), or make it go up with an explosion, among others.
It's typically referred to as the "Normal" force.
Lift is the upward force that opposes gravity.
No, gravity is a downward force.
Buoyancy
Lift is the upward force that opposes the force of gravity.
'Lift' is an upward force on a plane. Upward force on a bird's wings is also called 'Lift'.
The upward force is drag.
The upward force exerted on an object in a fluid is buoyancy.
buoyancy is the upward force that water exerts on an object. :)
Lift is the upward force that opposes the force of gravity.
'Lift' is an upward force on a plane. Upward force on a bird's wings is also called 'Lift'.
The upward force is the same in both directions.
The upward force is drag.
It is a force which acts in the upward direction.
The upward force exerted on an object in a fluid is buoyancy.
buoyancy is the upward force that water exerts on an object. :)
The upward force exerted on an object in a fluid is buoyancy.
the upward force of displaced fluid causing flotation is a buoyant force.
No, gravity is a downward force.
The Buoyant Force
Float. Essentially, an upward force is larger than the downward force, therefore the upward force wins.
