OUTCOME
By the end of the lesson you will be able to recognise and use Newtons second law in problems and apply trigonometry to solve incline plane problems.
Newton's second law is applied to many situations. The key to remember is that the second law applies to the net forces acting. The motion observed is aways a consequence of a variety of forces and their net force is what we use to determine the acceleration (if it exists)
