I'll revive this fairly deceased blog by re-initiating scribing. *cough* bonus marks *cough* I mean there is a test tomorrow on the unit, dynamics - a branch of mechanics that deals with forces and their relations to patterns of motion. I posted the sheet consisting of anagrams because it was from the past and no one was blogging for quite a while. Okay, so euphemistically, there is a lovely and highly admired test tomorrow. Good luck to everyone. There is an immaculate review below as posted by our teacher to remedy any difficulties that one may stumble upon while writing the test. Below are sheets I scanned, so feel free to browse.
remember that there is no air resistance when a rock is in free fall. that was my first instinct but then i asked for the opinions of others
for 8b) Ms. K said the answer being force RESISTING the car's motion was 3740N, but I still object. The force of the car caused by acceleration is 3740N as calculated by multiplying the mass and acceleration. To further justify, it states that the force put on the wheels due to the road is 5600N, which is a frictional force and what we are trying to find is the resisting force being the force impeding the car. So I obtain the difference between the two resultant forces which results in 1860 N [East]. Friction resists, so this is the resisting force.
We went through the sheets above and received back our assignment on vectors. Well this is a fairly accurate summation of class today. I dub the next scribe Sir Dion Palumbo. He's a lucky duck to be the scribe for the day of the test. Thou shall scribe effortlessly because of the sympathetic initiator.

Net force is the force causing the acceleration-it can't be the frictional force in this case.
