Force on a particle having mass m is given by,

$$\vec{F} = m\vec{a}$$

Where, \(\vec{a}\) is the acceleration of the particle.

- SI unit of force is Newton ( N ), which is equal to kilogram metre per second ( kg m s
^{-1}).

CGS unit of force is dyne.

## Learn some extra:

### What is the value of 1N in terms of fundamental units?

As we know that,

F = ma

So, 1N = 1 kg × 1m s^{-2}

Or, 1N = 1 kg m s^{-2}

So, the value of 1N in terms of fundamental units is 1 kg m s^{-2}.

### What is the value of 1dyne in terms of cgs units?

As we know that,

F = ma

So, 1dyne = 1 g × 1cm s^{-2}

Or, 1dyne = 1 g cm s^{-2}

So, the value of 1dyne in terms of cgs units is 1 g cm s^{-2}.

### What is the relation between newton and dyne?

As we know that,

F = ma

So, 1N = 1 kg × 1m s^{-2}

Or, 1N = 10^{3}g × 10^{2}cm s^{-2}

Or, 1N = 10^{5} g cm s^{-2}

Or, 1N = 10^{5} dyne

So, the 1N is equal to 10^{5} dyne.
