national 5 exam questions – electricity and energy

Here are the exam-style questions to cover the electricity and energy unit.  I have included a copy of the relationships (equation) sheet and some data tables that you may need to attempt all the questions.  Apologies for the larger file size, it’s due to all the circuit diagrams.

S4: work done, potential and kinetic energy

We finished the transport section with a look at Work, Potential & Kinetic energy.  Those of you aiming for Credit need to carry out calculations involving kinetic energy using

E_k = \displaystyle {1 \over 2}mv^2

Here is a video about work, potential energy & kinetic energy from Bozeman Science

Most of the calculations will be based on the principle of conservation of energy.  Dr. Altman has an excellent series of videos examining conservation of energy  examples from Roadrunner cartoons.

I have attached a pdf handout with worked examples on potential energy, work and kinetic energy.  If you want some more revision materials, try here.
