PHYSICS: So why don’t things that are moving just keep moving? Here’s the intro lecture on friction. Remember a few key things. Net forces produce acceleration. You can find Ff a couple of different ways – it’ll be part of a net force equation and can be found from the coefficient of friction equation. If and ONLY if your object is moving at a constant velocity, Ff will equal Fa. Fn is only sometimes equal to Fw. If your object is pulled at any angle (or pushed), Fn will be a part of Fnet in the vertical direction. Whew!
Have a great time at the polls tomorrow! Be safe!!
Ms. Skinner, do you have any tips for keeping track of all of the forces? I’m drawing pictures, but I feel like I’m forgetting forces.
Ahh! I forgot to write my name correctly!
Can we have a help session? Possibly before next week before the play hits?
I second this! All te different forces are kicking my tail.
Will we be putting all of these forces on our equations card?
