You might have noticed my flurry of posts in ~Science because I want to consolidate my knowledge (and uncover my misconceptions) before my children undertake their educational journey. Recently, I thought i should explore how Big Ideas are connected from one stage of the system to the next instead of focusing myopically on primary school Science.
Here’s something about forces and energy:
Primary School | Secondary School |
---|---|
A force is a push or a pull | A force is a push or a pull |
Energy is needed to perform life processes | Energy is needed to do work |
Gravitational potential energy, kinetic energy | GPE + KE = Mechanical Energy |
No formulae learnt | W = F x d, GPE = mgh, KE = 1/2mv^2^ |
Incidentally, work done is the product of a force and the distance moved by the object in the direction of the force. This reminds me that I should align my life energy with the things that matter most to me and expend in on ways that will lead me to get those things. Otherwise, zero work done!
