Grade 11 Forces and Motion

If a net force diagram is drawn, such as shown, wherein the [math]F_"norm"" at A "=-(F_g)" at C"[/math], what do you know about the object?
Free Body Diagrams 4
  1. The object is accelerating in the direction of the [math]F_"app"" at B"[/math] because there is no opposing force to B, and [math]F_"app"" at "B>0N[/math].
  2. The object is accelerating in the opposite direction of [math]F_"app"" at B"[/math] because forces act in equal but opposite pairs.
  3. The object is not moving because the [math]F_"net"=F_"norm"+F_g=0N[/math].
  4. The object is accelerating in the direction of the [math]F_"app"" at B"[/math] because the opposing [math]F_"fric"[/math] must be negligible, and [math]F_"app"" at "B>0N[/math].
