The newton-second is the unit of impulse in the International System of Units (SI). It is dimensionally equivalent to the momentum unit kilogram-metre per second (kg⋅m/s). One newton-second corresponds to a one-newton force applied for one second.
Definition
Momentum is given by the formula: :\mathbf{p} = m \mathbf{v}, • \mathbf{p} is the momentum in newton-seconds (N⋅s) or "kilogram-metres per second" (kg⋅m/s) • m is the mass in kilograms (kg) • \mathbf{v} is the velocity in metres per second (m/s) ==Examples==
