∙ 13y agoFg=mg
g=9.8 m/s2
m=1 kg
Fg=9.8 N
And we know that the net force is 0, since the object is at rest.

Normal force from the table - keeping the book off the floor - if book is not moving - also = mg

2) The book pushes down against the table; the table pushes up against the book.

∙ 13y agoIf the velocity is constant (not changing) then the net force is 0. Likely there is a pushing force that is equal and opposite of the force of friction.

What is net external force?
The Net external forces is the result force of two objects acting upon it. So if like two forces act on a book. One force exerts downward on the book and the other force pushes the table back on the book with the same amount of push and pull. Since both forces are pushing on each other with the same amount of energy the resultant force or net external force will be in equilibrium or zero.
What do electric forces act between?
Electrical forces act between separated charges.
What is congruent forces?
Foreces that are applied to or act at the same point.
What two forces act on the paper cup as the repeling magnets contend to keep it in this position?
Gravitational force (gravity) acting downwards and the normal force of the table acting on the cup upwards. These two forces when added together equal zero. Therefore, there is no movement. They keep that cup and its contents in position.
How do contact forces such as friction differ from gravitational and magnetic forces?
Contact forces must be touching whatever they are acting on the others have a field of influence around them; ie they don't have to touch to act on something
What forces act upon a book sitting on a table?
Action and reaction
Forces that act upon cars are?
Gravity, Air resistence, friction and the push from the floor/table
What forces act on a frictionless air puck as it moves across a table at constant speed in a straight line?
Gravith pulls it down; table pushes it up.

What is the grammatical difference between setting and sitting?
setting is the act of putting something somewhere else ie- setting the the table sitting is being a position where you knees and waist are bent at approximately a 90 degree angle
Is the publication in which Sir Isaac Newton described forces and how they act?
This book is Philosophiae Naturalis Principia Mathematica.
What force is acted on by another?
Forces don't act on other forces - forces act on objects.
What forces act on a frictionless air puck as it moves across a table in a straight line?
The force of air from the airholes on the puck, and the resultant force. A shear force (v). Velocity and acceleration forces, as well as gravity.
What are the forces that Osiris and Isis represent and how does Horus act as the horizon between them?
The answer to this is in your text book. Stop short-cutting and read it.
What forces act on a plane sitting still on the tarmac?
It has weight-- but not lift. It also has no thrust nor drag. It needs forward movement/trust, velocity, and lift to get off the ground.
What do electric forces act between?
Electrical forces act between separated charges.
What is some examples of long range force?
Long range forces are forces that act over a long distance, like electric forces, magnetic forces, or gravity.Long range forces are forces that act over a long distance, like electric forces, magnetic forces, or gravity.Long range forces are forces that act over a long distance, like electric forces, magnetic forces, or gravity.Long range forces are forces that act over a long distance, like electric forces, magnetic forces, or gravity.
