A Day of Variety

Physics B reviewed their projectile motion lab and their work on resolving vectors before plunging headlong into the topic of non-perpendicular vectors. Make sure to carefully follow the steps we listed in class and pay attention to the sign of each vector. The video posted yesterday will give you a review of this process if you need a little reminding. Tomorrow, we'll go over these problems and then take a deeper look into the properties of horizontally-launched projectiles.

Physics A investigated the motion of a horizontally-launched projectile during today's long block. With a few measurements, folks were able to calculate a target distance and land a ball bearing right in a plastic cup. Then, the task was to calculate and set a launch velocity to hit a given target distance. We'll go over the lab tomorrow before we review our work on non-perpendicular vectors. Then, we'll use the lab to highlight the general discussion about properties of horizontally-launched projectiles. If you didn't get a chance to copy the Summary of Results and Conclusion ideas from the board, check out yesterday's post...

Introductory Physics took their graphing motion and kinematics quiz. Overall, the kinematics portion wasn't bad, but the graphing still needs work. That's fine...we have time...

Honors Physics had their test postponed until tomorrow. With 5 students being dismissed 25 minutes early and another few being absent, giving the exam today wasn't perhaps the best use of time. So, students had more review time and we'll work on the exam tomorrow in class. Time permitting, we'll conduct some investigation associated with forces, but we'll have to see how the period plays out...
