An object travels in a circular path of radius 5.0 meters at a uniform speed of 10. m/s. What is the magnitude of the object's acceleration?
20cm divided by 2N means it creates the pressure of 10Ncm2
Gram-force is the gravity force generated by a gram of material, so a gram of metal on a table would exert one gram-force on the table. A milligram is 1/1000th of a gram, so a milligram of metal it would exert 1/1000 of a gram-force on the same table. For reference, 1 kilogram of material exerts about 9.8N of force (1 kg * 9.8 m/s2), so a milligram-froce would equal 0.0000098N.

There is not technically a formula for the Third Law of Motion. It is simply a concept that explains 'reactionary' forces that exist in our everyday life. Yet, symbolically, the Third Law of Motion can be depicted as: Fa = -Fb Force applied depicted as, Fa, is equal in magnitude but opposite in direction to Fb. An example of this idea would be if a person punched a concrete wall. The reason he is hurt by punching a concrete wall is because the wall applies a force equal in magnitude (as his applied force) but opposite in direction on the person.
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.
It is if a brick rests on a table the force with which the brick pushes on the table is its weight. The pressure it exerts on the contact area depends on the brick's orientation. If the contact area between brick and table is larger, the brick exerts less pressure on the contact area.
A box is sitting on a table. The upward force exerted on the box that stops it from falling through the table is known as the force.
The force exerted on the table by a ball IS the weight of the ball.
because the table exerts the same amount of force
It states that if an object "A" exerts a force on object "B", then there will be a force of equal magnitude, and in the opposite direction, from object "B" against object "A". Thus, the forces always come in pairs.
20cm divided by 2N means it creates the pressure of 10Ncm2
Reactive force. For every action there is an equal but opposite reaction. So if a box is sitting on the table, and the box weighs one kg, it exerts 9.81N of force on the table. Likewise, the table exerts 9.81N of force on the box in order to keep the box on the table. Otherwise, the box would smash through the table. THESE TWO FORCES ARE EQUAL BUT OPPOSITE, SO THE SUM OF THE TWO WILL ALWAYS BE EQUAL TO ZERO.
A textbook on a table is an example of balanced forces. The force of gravity pulling the book downward is balanced by the normal force exerted by the table in the upward direction, resulting in the book remaining stationary on the table.

The kid exerted lots of force to move the table.

Assuming that the seat of the chair is horizontal, and you an penis d the chair are stationary, the key forces here are your weight, which is acting vertically downwards on to the chair, and an equal reaction force, or normal contact force, of the chair acting on you. This force acts vertically upwards. You could also include the forces of the air acting on you and vice versa, but this is probably not what you're after.
