Question

If impulse = force * time and the SI unit of force
is newton (N), then the SI unit of impulse is

Answer 1

Answer:

SI unit of impulse = N s

                             = kg m/s

Explanation:

Impulse = Force * Time

[Impulse] = [Force] * [Time]

[Impulse] = N * s = N s

We also know that,

Force = Mass * Acceleration

[Force] = [Mass] * [Acceleration]

[Force] = kg m/s²

Hence,

[Impulse] = N s

[Impulse] = kg m/s² × s

[Impulse] = kg m/s

Answer 2

Answer:

SI unit of impulse = N s

                            = kg m/s

Explanation:

Impulse = Force * Time

[Impulse] = [Force] * [Time]

[Impulse] = N * s = N s

We also know that,

Force = Mass * Acceleration

[Force] = [Mass] * [Acceleration]

[Force] = kg m/s²

Hence,

[Impulse] = N s

[Impulse] = kg m/s² × s

[Impulse] = kg m/s
