1) What is force? How do two bodies exert force on each other?
2) Two forces are acting on a body such that F, - SN and F, -ION. Can you say that
resultant force on the body is 15 N? Why I why not?
3) What is a vector quantity? Give examples.
4) How does a force of 10 N differ from a force of -10 N?
5) What do you mean by state of motion? What are the parameters to measuri Can body
rest be described by these parameters?

Explanation:
hey brother gm
let's discuss 1 by 1....
1)force is described as intuitively as a pull or push,and it has both direction and magnitude.
As objects with mass exert forces on each other via the force of gravity.This force is directly proportional to product of their masses and inversely proportional to square of their distance between them.
2)F¹=-5N
F²=-10N.
resultant force=?
look buddy,
Expalination:if the two forces are acting on the same direction then the forces will be added ,simillarly if the two forces are acting on apposite directions then they are substracted .
solution: if the forces are acting on the same direction
then,F=F¹+F²
=-5N+(-10N)
=-15N
simillarly, if forces are acting opposite
then, F=F¹-F²
=-5N-(-10N)
=10N
3)A quantity which as both magnitude and direction is known as vector quantity.
ex:accleration,speed and displacement etc.,
