SYSTEM OF FORCES

FORCE

                           Force is an agent or cause which when applied on a body , it tends to move along a straight line at a uniform velocity.

                           Force is a vector quantity having both magnitude and direction.

UNITS

1.       M.K.S – Kilogram force (kgf)

2.       S.I – Newton

3.       C.G.S – Dyne

4.       F.P.S – Pownda

F=mf   

·         1 n = 1 kg x 1 m/s²

·         1 kgf = gn ( g = accedcaration due to gravity )

       = 9.81 n

=9.81 kg – m/s²

1.       1KN = 10³ N

2.       1MN = 10⁶ N

3.       1GN = 10⁹ N
