Forces: This week we are going to learn about forces and how to apply them to our lives. With this we are going to need to have a full grasp of the kinematics equations also because using F=ma to solve for acceleration allows us to use the acceleration to then figure out how things will move.

Components of force on a ramp: http://www.youtube.com/watch?v=uC5CG3Ji02E

Watch from 7:00 to the end

Friction Practice Problem: http://www.youtube.com/watch?v=YoxbplnG2FQ

Falling boxes friction/tension systems: http://www.youtube.com/watch?v=uvm8LsGB9DQ

Start at: 3:40

Equations:

F=ma

Force and Acceleration parallel to a ramp incline.

F=m(9.81)sin(angle) a=9.81sin(angle)

Normal Force Perpendicular to a ramp incline.

Fn=m(9.81)cos(angle)

Friction

F=Fn(constant) the constant is either mu sub s for static (not moving) friction or mu sub k for kinetic
