More Vectors!

Today, various discussions were launched for vector resolution and working with non-perpendicular vectors. Both vector combination and vector resolution are going to be used this year as we work with things like force and momentum, so make sure that you are very confident in your vector operation skills. Non-perpendicular vectors are the test - if you can successfully work problems with non-perpendicular vectors, then you can wear the vector crown with pride...

Tomorrow, we'll review these ideas and apply them to the concept of horizontally-launched projectiles. When motion occurs in two dimensions, as it does with projectiles, we have to be able to break a launch velocity into it's horizontal and vertical components to analyze the motion. The lab we'll do for this section will let folks work with horizontally-launched projectiles and give groups a chance to mathematically predict where a ball will fall. Yes... there will be prizes involved...
