If you are to teach acceleration, as a topic, to a low-performing Grade 7 class, how would you do it?
You are tasked to train fellow educators on the 2nd Law of Motion. These trainees admit that they find the topic difficult. Outline a procedure on how you will teach the trainees. Include in the outline some common misconceptions that you need to address as Trainor.
