SPACE:
Mass is a measure of how much material is in an object, but weight is a measure of the gravitational force exerted on that material in a gravitational field; thus, mass and weight are proportional to each other, with the acceleration due to gravity as the proportionality constant. (know more about icse board papers 2013, here)
w=m*g
w is the weight
m is the mass.
g is the acceleration due to gravity.
g=9.8 m/sec>2
Relation between objects in space
Relation between objects in space follows the newtons gravitational law of gravitational
Newton's Universal Law of Gravitation states that any two objects exert a gravitational force of attraction on each other. The direction of the force is along the line joining the objects
Newton's law of gravitation resembles Coulomb's law of electrical forces, which is used to calculate the magnitude of electrical force between two charged bodies and this signifies the Object And Space Relationship.
.The magnitude of the force is proportional to the product of the gravitational masses of the objects, and inversely proportional to the square of the distance between them .
F(1,2)=(G*m1*m2)/r>2
m1 & m2 are the objects in space
m1 exerts force F12 on m2
m2 exerts force F21 on m1
G is the gravitational contant which is 6.67 x 10>- 11 N m>2/kg>2
it is resposible for keeping all the object in the universe in there orbit , otherwise all objects would have collide
In the next session we will discuss about Graphing solutions of inequalities.
- space is a three dimentional structure
- space is boundless and limitless.
- space contains object exist in space
- many events exist in space
- object is a physical body which is a collection of masses.

- The inertial mass of an object determines the amount of force needed to produce a given acceleration of that object.
- The gravitational mass determines the force of gravitational attraction between two bodies.
