What kind of quantity is force

Force is a vector quantity, as both direction and magnitude are important

what can be used to measure force

spring balance can be used

SI unit

newton [N]

other units

kg m/s^2 and kgf

1 kg m/s^2 =

1 N

1 kgf

9.8 N

1 gram force is

the force required to move a body of mass 1 g towards itself or the force required to lift a body of mass 1 g vertically upward

1 kgf is

The amount of force required to move a body of mass 1 kg towards itself or in the vertically upward direction.

1 dyne [CGS unit of force]

10^-5 N

what happens if a body is fixed on a pivot at force is applied to it

the body will turn on its pivot

moment of force

it is the product of the magnitude of force and perpendicular distance between the pivotal point and the point of application of force

moment of force =

force*perpendicular distance

SI unit

newton meter [Nm]

1 kgfm =

9.8 Nm

CGS unit

dyne cm

1 dyne cm =

10^-5 N * 10^-2 cm = 10^-7 Nm
