Standard Grade Fizzics

We finished the Energy Matters topic last week.  Here are some notes with worked examples to show how we calculate the heat energy required to change the state of matter.  Values of Lf and Lv are provided inside the front cover of a question paper. We’ll finish off the course by looking at Space Physics.

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 Here is a video about work, potential energy & kinetic energy from Bozeman Science //www.youtube.com/watch?v=BSWl_Zj-CZs Most of the calculations will be based on the principle of ...

We’ve been learning about forces in class and today we looked at how car seatbelts use forces to keep us safe.  Mr Mallon’s HelpMyPhysics site has a short video that demonstrates how a monkey can stay safe during a trolley collision when it is given a seatbelt. Here is a seatbelt advert from Sussex, the ... Read more

Last week, the BBC broadcast a Horizon programme about new cancer treatments being trialled at the Royal Marsden Hospital in London.  The documentary followed three different types of treatment; robotic surgery, a genetically targeted drug and a radiotherapy robot. As we’ve discovered, standard radiotherapy treatment involves splitting the required dose into 3 beams, so only cells inside ... Read more
