2. DEFINATION  It is defined as an agent which produces or tends to produce, destroy or tends to destroy motion.  The force may not necessary produce a motion in a body but it may tends to do so.

3. UNIT OF FORCE  In S.I. system-Newton-kg.m/sec2  C.G.S. system-Dyne-g.cm/sec2  F.P.S. system-FP/sec2

4. EFFECT OF FORCE  It may changes the motion of a body, if a body is at rest, the force may set in motion.  It may retarired the motion of the body.  It may retaired the forces, already acting on a body, thus bringing it to rest or in equilibrium.

5. CLASSIFY FORCES It is 7 types of force  Co-planner forces.  co-llinear force.  Con-current forces.  Co-planner concurrent forces.  Co-planner non-concurrent forces.  Non-co-planner con-current forces.  Non-coplaner non-concurrent forces.

6. CO-PLANER FORCES  If the forces whose lines f action lie in the same plane is called as co-planer forces.

7. CO-LLINEAR FORCE  If the forces whose lines of action lie on the same line is called as collinear forces

8. CON-CURRENT FORCES.  The forces, which meet at on point is known as con-current forces. it may be or may not be collinear.

9.  The forces which meet at one point and their lines of outing line on the same plane are known as co-planer concurrent forces. CO-PLANER CON- CUNCURRENT FORCES

10.  The forces which don’t meet at one point but their lines of action lie on the same plane are known as co- planer non-concurrent forces. CO-PLANER NON- CONCURRENT FORCES

11. NON-CO-PLANNER CON-CURRENT FORCES  The forces which meet at one point but their lines of action don’t lie on the same plane are known as Non- coplanar con-current forces.

12. NON-COPLANER NON- COCURRENT FORCE  The forces which don’t meet at one point and their lines of action don’t lie on same plane are called Non- coplanar Non-concurrent forces
