The newton-second (also newton second; symbol: N⋅s or N s) [1] 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. It can be used to identify the resultant ...

In the curriculum, physical science is one of the core subjects offered across all tracks in Grade 11 and Grade 12, which requires 80 h/semester. The course deals with the evolution of one’s understanding of matter, motion, electricity, magnetism, light, and the universe from ancient times to the present.
