Hi there,
Yes, it's all at a basic level. Some of the things to look at are...
- manipulating algebra (e.g. a*b = c becomes a = c/b )
- resolving forces
- trigonometry
- electronics - resistance, capacitance, reactance, inductance, power
- moments
- basic understanding of concepts like work, power, torque, inertia
- mass and density
- gas laws
Um, brain gone blank. Hope that helps a bit.
