Physics 2a - Remembering your Units!!

A big mistake made by students when they are trying to use formula triangles is that they always number crunch with the wrong units! Physics 2a is FILLED with formula triangles, and I felt that it was just important to make a post which would go through all of the units that you need to know. Read through the list, and try to familiarize or even remember them! ...

And here the list begins..

Acceleration - m/s²

Velocity - m/s (+ a direction)

Time - secs

Distance - m

Speed - m/s

Force - N

Mass - kg

Weight - N

Gravity - N/kg

Work Done - J

Energy Transfer - J

Gravitational Potential Energy - J

Height - m

Kinetic Energy - J

Power - W or J/s

Momentum - kgm/s

Confused?

Read through my other blog posts to see the formula triangles in which these units are used..

Hopefully that will help :)
