Applying Newton's third law gave us the conservation of momentum. The experiments showed that momentum is conserved if there are no external forces (like friction or someone giving it a push !)
There is a formal definition you need to learn but more of that next lesson.
For Friday you must take a long hard look at your notes - the test is on Tuesday......use the LOs - can you colour them green / tick them off. Don't forget to bring in any queries and either see me before class on Friday or ask during class.
No formal homework but revision is the order of the day. Use the questions in your notes.....don't just look at them try them again.
Good luck and happy revising
Mrs M :-)
