Learn by heart all the derivations. or understand it and use ur brain to derive it onur own

Think about what the units are in the equations

for example:

velocity/time = acceleration.

The units for velocity is metres per second

The units for time is second

Therefore, the units for acceleration is metres per second per second, or metres per (second)^2
