Going over homework in this way I hope helps you to 'see' where you can avoid making erorrs.

I know that writing down data and equations may seem tiresome, but it is important and could save you marks!!!

This way you can avoid needless errors.

So don't take short cuts follow the rules :-)

Thanks to Ollie we 'saw' the balanced equal and opposite forces that led us to Newton's 3rd Law....It is important that you learn this definition (just as you have learned Newton 1 and Newton 2....you have...haven't you ?)

Identifying paired forces can be tricky but you were getting the hang of it by the last few examples. Just remember you only look at one point....not every where at once.

So what does Newton's Third law also mean.....momentum and trolleys colliding. This is what we will do next time.

Don't forget your homework and start revising for the test....

Great lesson ..well done
