Here is a short video covering the points we discussed when we drew scale diagrams to find displacement vectors.
We’ve been dealing with vectors since the very start of the Higher Physics course. Before the holidays, we looked at displacement, velocity and acceleration as vectors. Over the last 2 weeks, we have discussed velocity in the context of projectile motion and looked at the vector nature of forces.
Some of the problem solving tasks we attempted towards the end of last week suggested people were a little rusty on vectors so I have looked out some youtube revision materials to jog the memory.
Sometimes clips go into too much detail for our course or start introducing alternative methods that we have not used in class. To prevent confusion, I’ve suggested how much of each video is relevant for the Higher course.
The first 6 minutes of this video clip introducing vectors may be helpful.
Watch this one up to 2:50 for a good review of our June work on displacement.
