DEFINATIONDEFINATION

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.

EFFECT OF FORCEEFFECT 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.

CLASSIFY FORCESCLASSIFY 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.

CO-PLANER FORCES

If the forces whose lines f action lie in the same plane is called as co-planer forces.

CO-LLINEAR FORCE

If the forces whose lines of action lie on the same line is called as collinear forces

CON-CURRENT FORCES.

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

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

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

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.

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
